On this page What is loathsome to me? Why do I write these pages? My background My greatest concerns Two long walks A fortunate life Elysium Environment and me CO2 production calculation CO2 abatement calculation Buying green electricity Influences Information sources My affiliations Books Revegetation A purpose Best thing I've done? Minimalism Achievement The inevitable - ageing The end Index   As I write these pages I am not beholden to any political party, any lobby group or any corporation. I do not seek financial support from any advertiser or anyone else. I write as a 'free spirit' on whatever subject takes my interest. Of course I try to write only facts or opinions that can be supported by sound evidence. What is precious to me? My family; Truth; The natural world, our planet Earth; The advance of science and the fight against ignorance and delusion (including religion and other superstitions); Philosophy – including especially moral philosophy (ethics); The arts; Friends; Freedom. Truth is of huge importance and it is under siege in this age perhaps more than any other, particularly from people like US President Donald Trump, and Australian Prime Ministers Abbott and Morrison. Religion and other superstitions are delusions that stop many of us from seeing the truth. We must all (certainly including myself) continually examine ourselves and our beliefs, searching for possible delusions. The natural world, our living environment and the non-living part of the biosphere that supports life, must be protected if the lives of all of us, and our decedents, are not to be greatly degraded. This of course includes the atmosphere and oceans (climate change, ocean warming, ocean acidification and sea level rise). A related problem is the air pollution from the burning of fossil fuels that kills millions of people world-wide each year. The natural world is more under threat today than ever before; at a time when altruism toward nature is required, people seem to be just as selfish and short-sited as ever; will they ever realise that without our environment we have nothing? I have decided to do all I can in the remainder of my life to try to get serious action on climate change; I believe that having compassion for all life demands this.   Flinders Ranges Native cypress trees Science has much in common with truth; it is a method of discovering the truth. The scientific method is probably the greatest discovery of Mankind. Science has shown us how the Universe works and has brought us most of what is good about our present civilisation; it has brought us knowledge. But science is under attack from those who do not like what it is showing us; in particular those religious people who deny evolution and from climate science deniers. And a great many people are either unable or unwilling to think critically about their beliefs and are simply delusional. Philosophy teaches us to evaluate arguments and to critically look at all beliefs and opinions. Moral philosophy, ethics, informs us of how we should live. Philosophy places everything, including science and truth, into context.   Home Top Index The arts: Some of the greatest creations of the human spirit; Music: I could list hundreds of pieces here – in no particular order – Tchaikovsky Piano Concerto No. 1; Borodin Nocturne from String Quartet No. 2 in D Major; Dvorak Part six of his Stabat Mater; Tenore solo, Coro. Andante con moto (Fac me vere tecum flere); Geroges Bizet Au fond du temple saint (In the Depths of the Temple); Sibelius Finlandia; Pachelbel Canon; Rachmaninoff piano concerto No. 2; J. S. Bach air on a string of G; Handel Messiah; Ombra mai fu; Grieg The Four Seasons; The Morning from Peer Gynt; Jeffes Music for a found Harmonium; Vaughan Williams The Lark Ascending; Ennio Morricone & Chiara Ferrau Nella Fantasia; And how could I miss Beethoven, particularly for his ninth symphony. Painting: A very rough selection of a few of my favourite painters, again in no particular order – Hans Heysen (Australian; particularly known for his paintings of gum trees and the Flinders Ranges); Rembrandt; J. M. W. Turner; John Constable; H. J. Johnstone (I am in love with a single work of his: "Evening Shadows – Backwaters of the Murray" in the Art Gallery of South Australia) The Heidelberg School; particularly: Tom Roberts; Frederick McCubbin; Arthur Streeton; Art is for all of us, we should not let so-called art experts tell us what is good and bad art. Islam's antipathy to the arts is one reason I loathe and fear that religion. Friends; I don't have a lot. I haven't met many people who think like me. Those I have are precious. A Walk for Solar Power in 2012 and the Climate Walk, two years later, significantly increased the number of people I know who think like me, and, I would like to think, the number of my friends. Freedom; The freedom to do whatever one wants to do, within ethical limits: freedom of speech, freedom of thought, freedom of belief, freedom of the media (under threat as I write in Australia and elsewhere), the freedom of whistle-blowers to report wrong-doing, freedom to pursue knowledge; freedom from institutionalised misinformation as exists in places like China, North Korea and increasingly in the USA and Australia; freedom from discrimination; the freedom to die if, when and how we want to. Freedom cannot exist under a theocratic government as in Iran and some other countries and states under the yoke of the Islamic delusion. Freedom did not exist in Europe while Christianity dominated thought there. What is loathsome to me? Anti-science Lies Delusion, self-deception and superstition Ignorance Greed Corrupt government   Rottnest Island wind turbine This is the wind turbine that PM Abbott claimed he found so objectionable. Anti-science; the activity of the climate science deniers, those who make up lies about wind power, and those who try to discredit science for whatever purpose. Lies from people who cannot support their arguments with valid and rational evidence, or who simply don't bother trying to discover the truth. I hold that those in a position of power who lie (rather than make false statements through ignorance) in order to support the fossil fuel industry or to hold back climate change action are among the greatest criminals in history. (It is interesting that opposition to wind power is often based on fallacies and selfishness while opposition to coal is based on concern for our shared environment.) Delusion and superstition; the beliefs held without supporting evidence; including minor delusions such as divination and that great delusion, religion. (Of course there are many very good people who are deluded; but they are good in spite of their delusions rather than because of them.) There is little difference between self deception and delusion. Ignorance allows the anti-science forces and the liars to get away with their activities. "Not to know is bad; not to wish to know is worse." African proverb Greed; the greed of those who can never have enough money (and the power that comes with wealth) is doing great harm to the world. Society should condemn such people, instead there seems to be a twisted form of hero-worship. Governments should be working toward redistributing the wealth that is in so few hands; instead they seem content to allow the rich to become richer and the poor to become poorer. (I've written pages on corporate greed and contribution to society.)   Home Top Index Corrupt government; such as the Australian Liberal governments of Abbott, Turnbull and Morrison, who have served the short-term interests of the fossil fuel industries and the greedy rather than the long-term good of the nation, the planet and all people. The Australian Labor Party is also corrupted by its protection of the interests of the fossil fuel industries above the long term good. Australia has far too many politicians who do not fulfil their responsibilities, such as, the 'awful example', Andrew Hastie. Why do I write these pages? Since about 1985 I've been writing letters to the editors of local, state, and Australian national newspapers because I felt an obligation to at least try to dispel lies, delusions and self-deception, and to make the world a better place.   Faults I am no saint. My wife and I have two properties 75km apart; travelling between the two over the years has burned a lot of fossil fuel and released a lot of carbon dioxide; We enjoy holidays interstate (some driving with a camper trailer, some flying) and overseas (flying), again, lots of carbon dioxide; I eat meat, vegetarianism is easier on the environment and more ethical; I'm sure that, if I gave the matter more thought, I'd be able to list other faults; There are many things that I have done that I regret. "The only thing necessary for the triumph of evil is for good men to do nothing." Edmund Burke "I aimed to make the Earth a better place – and failed miserably" Professor Harry Messell (However, the world was a better place for his having lived.) When the Internet became a popular way of spreading ideas I started these pages. I'm not sure when I started; two of the earliest pages were on divining and religion, both written about September 2001. In 2002 I wrote a page on 'The Real USA' because the pandering to the US by Australian governments, both Labor and Liberal, sickened me. I wanted to show that much of what various US administrations had been up to was far from honourable. This was for a few years one of the most visited of my pages. With the election of Donald Trump the USA has certainly deteriorated further than its position in 2002. In 2020 Australian governments continue their shameful pandering to the USA. Early in 2004 I started writing my pages on wind power. (I had followed the development of wind and solar power with interest since before the construction of Australia's first wind farm at Esperance in 1987.) The aim of those particular pages was to give the facts, and make an effort to dispel the myths, about wind power. I am convinced that the greatest single threat facing the world in the early twenty-first century is climate change and one thing we can do to greatly slow climate change is to replace fossil fuel electricity generation with renewable energy as quickly as possible. In terms of achievement, I suspect that spreading the facts about wind power is the best thing I've ever done.   A wind farm in Mid North South Australia A very small part of North Brown Hill Wind Farm, near Jamestown, in wheat and canola fields Photographed by my drone, 2017/09/15   If we had to answer to a higher authority If there was a higher authority to whom we had to answer after our deaths (of course there is not) and he/she/it asked me “What have you done in your life that has justified your existence?” One thing I would say in reply is that I have publicly exposed and refuted the lies of those who have dishonestly opposed the wind power that the world must have if we are to combat climate change. I have shown people the truth. While the lies of the opponents of wind power is only one of a great many injustices in this world, I suspect that this is where I have had the greatest impact and the most good I have managed to do in my life. The fight against the purveyors of misinformation on wind power is a never ending job; there are many people with many reasons for trying to discredit this major renewable energy technology; and many of them are not above lying in the effort to achieve their ends. (The lies and misinformation continued in 2024 with federal Liberal politician Andrew Hastie's scare campaign against offshore wind power in WA.) Many of those who are opposed to wind power also deny climate science because they see that climate change demands moving away from fossil fuels to renewable energy. To oppose wind power is to support the coal industry by default; air pollution from the mining, transport and particularly the burning of coal kills millions of people world wide each year. People like Andrew Bolt, Alan Jones and Ian Plimer who make a very lucrative (although hardly a respectable) living out of opposing action on climate change, probably don't believe much of what they write and say; they are simply cynically working for the fossil fuel industry and pandering to the ignorant. I believe that it is necessary to show that much of what they claim is false by giving the evidence behind the truth. On 'the same side' as Jones, Bolt and Plimer (perhaps the employers of Jones, Bolt and Plimer, in a sense) are Gina Rinehart, Clive Palmer and Gautam Adani, who are probably only interested in the money that they can make out of anything at all, it just happens that they have chosen coal; they are motivated by greed, they simply don't care about the future of the planet. Similarly, Rupert Murdoch has done enormous damage to the world by his purveying of lies about climate change, fossil fuels and renewable energy. A paraphrasing of Mark 8:36 is appropriate here: "For what does it profit a man to gain the whole world if it means forfeiting his self respect and earning the contempt of decent people." Then there are the well meaning, but deluded people, like (ex Dr) Sarah Laurie, who believe most of what they say, but do a great deal of harm. Their claims need to be debunked. Finally there are the many who are best characterised as ignorant, ill-informed and/or selfish and those who are simply undecided but open-minded. I have no expectation of changing the ways of the Bolts and Joneses of this world, I write in the hope of getting through to at least a few of those whose minds are not closed. "A mind is like a parachute. It doesn't work if it is not open." Frank Zappa   Home Top Index Like so many idealists I hold that it is important to consider the needs of others, including those yet to be born, that one has a responsibility to be well informed and examine one's beliefs, and that there are more important things than one's own short-term selfish interests. I believe that compassion is one of the greatest virtues. My family and me I am the one with the grey beard One of my hobbies is photography There are a huge number of subjects about which I know very little. I write about those few subjects of which I have some knowledge. My Internet pages serve me as a reference, I often look back at things I've written to fill in some detail I had forgotten, or check on where the information came from. They have helped me, by allowing me to put thoughts into writing, decide what I believe to be right and wrong, reasonable and unreasonable; and decide on 'my view of the world'. Whether my pages are useful to others is something I know little about, but writing them is very important to me for several reasons: It allows me to record and organise my thoughts and opinions and discover deficiencies and possible delusions; I can refer to my earlier writing to remind me of past studies; It forces me to study and think about each subject as I write about it; It helps me to integrate my ideas, to make sure that there are no contradictions; I can update, correct, or improve past writings as I come across more information. My Internet pages have helped me to educate myself. The Internet is an ideal tool for doing this, it is ideal for spreading different subjects on different pages, it is easily searchable and one can use hyperlinks to provide connectivity.   Home Top Index The fact that the Internet makes my thoughts public concerns me little. The fact that it might be useful to others provides added incentive for writing. It is interesting that something I wrote years earlier generally fits with my current knowledge and beliefs. This could mean that I make few mistakes, or is it more likely that it means I am old and fixed in my ideas? "The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man." George Bernard Shaw "If you think you are too small to make a difference, you've never been in a room with a mosquito." Annita Roddick "Not to know is bad; not to wish to know is worse" African proverb You'd have to say that at least the first of the above quotes is simplistic, but it is also basically true; that being the case, I, as an unreasonable man, attempt to do my little bit to produce progress toward a saner, more ethical world (or perhaps at least to slow the decline toward insanity and self-destruction). It seems that the world is run by madmen (in January 2010, when the stresses that Mankind is placing on this planet should be obvious to all, the leaders of the two dominant political parties in Australia have both said that they believe Australia needs substantially more people, and quickly. Perhaps it is more than coincidence that these two men, Rudd and Abbott, are deeply religious.) The election of Donald Trump as President of the USA in 2016 greatly strengthened the impression that the world is run by madmen; and that many voters were remarkably stupid. My writing talents are ordinary, my intelligence likewise, my public speaking abilities nil; but if, by these pages, I can influence half a dozen people to give up superstition or try a bit harder to move the world away from its present race to environmental disaster, or even just to examine the world from a more rational or less selfish point of view, all the writing might have been worth-while. I feel I must try anyway; I dream of a better world. A disability: Why write and not speak publicly? I have never been a good speaker. I have always hated public speaking and always have trouble thinking of the words that I need at the time I need them. When I am debating something I often think of what I should have said about ten minutes after I needed to say it. Consequently, I avoid radio interviews and making public statements at inquiries, etc. I suspect that this limitation is sufficient to be called a mild disability. (Maybe it's more than a mild disability; maybe many people have the same disability?)   Home Top Index My background I was born in the mid 1940s near Adelaide in South Australia. I attended Charleston Primary School that at that time had husband and wife teachers. Mrs Arthur taught grades 1-3, Mr Arthur taught grades 4-7. Kids leaving Charleston Primary School had a reputation for having poor English language skills; I certainly did poorly in first year high school English. I went to the high school section of Oakbank Area School. There were only two of my teachers that I liked in high school and no doubt this was a major factor in me hating high school. Another factor was that I was no good at sport and hated having to participate. As subjects I loved mathematics and science. Had I enjoyed high school I probably would have completed it, doing five years rather than three, and gone on to do some sort of science course in university. For eight years after leaving school at age 15 I worked on the family dairy farm; where I educated myself (a very patchy education) from a set of Encyclopaedia Britannica (one of my best ever investments), subscribed to a science/maths educational magazine, taught myself some general science, some mineralogy and the qualitative chemical analysis of minerals, lapidary and astronomy and a little mathematics.   Aurland Fjord, Norway The life of a dairy farmer is hard and the hours are long – I gave it up and got a job with the Adelaide Metropolitan Fire Brigade. After realising that working as a fireman suited me no better than did dairy farming I lived and worked in the bush in WA and the Northern Territory (see below) in the mineral exploration industry for, I think, 17 months in total, finding that a year in the Australian bush living under canvas can be a great learning experience as well as very enjoyable. In this period I also did a seven week stint studying geology at a summer school in the University of Tasmania (late 1970), and greatly enjoyed it; my experience with university could hardly have been more different to my experience with high school. I sometimes wonder how my subsequent life would have differed had I gone on to finish a university degree. The stint in UniTas was followed by a year at a place called Bonya (in the Plenty River area) of the Northern Territory, also working in mineral exploration. In the NT we were mostly assessing several occurrences of scheelite, a calcium tungstate mineral and one of the main ores of tungsten.   Home Top Index Travelling overseas for eight months, starting in May 1972 in Portuguese Timor (as it was then) followed by a couple of months in Indonesia, on to Singapore and thence a month in Britain and three months in continental Western Europe, returning by the overland rout via Yugoslavia (as it was then), Greece, Turkey, Iran, Afghanistan, Pakistan, India, Thailand, Malaysia, and Singapore was another once-in-a-lifetime experience. The last thirty years of my 'working' life was in the hydrogeology (groundwater) field for the South Australian public service. It was in this period that I subscribed to Scientific American for about 30 years. Earlier I had subscribed to New Scientist, but found the weekly journal hard to keep up with, the monthly Scientific American suited me better. I married at the age of 32; my wife and I soon after had two children. We have been a close family ever since. (As of 2020 I have three grandchildren, aged 9, 7 and 4.) Hobbies in this time included cutting and polishing gemstones (including faceting), making silver (and a little gold) jewellery, building telescopes (first a 200mm diameter reflector, followed by a 300mm and finally a 400mm), and establishing and running the Bowman Park Astronomical Association (we had an observatory with a roll-off roof containing the 200mm and 400mm telescopes at Bowman Park for several years) and the Mid North Bushwalking and Cycling Club (we did quite a lot of one day walks and a few bush walks of several days - I only recall on cycle ride with the group). In this period I taught myself computer programming, first in BASIC and then Pascal; applied this to hydrogeology and wrote two books in Elsevier's Developments in Groundwater Science series: "Microcomputer Programs for Groundwater Studies" and "Groundwater Discharge Tests: Simulation and Analysis". The Public Service in South Australia at that time discouraged technical officers in hydrogeology from computer programming; computer specialists were employed to do that. Of course computer specialists know nothing about hydrogeology and would have been quite incapable of doing the more important of the work that I did. However, I was lucky enough to have encouragement from several superiors (who I have listed under Influences and I admired and appreciated greatly).   Home Top Index In the years from about 1989 to 2019 Denece and I went on a number of interstate and overseas holidays with our Son and Daughter; in the later part of that period our Son's and Daughter's spouses and children came too. We have been fortunate in having always been close to our 'kids'. In earlier times there had been at least an annual holiday while our kids were growing up. Since 'retiring' most of my time is taken up with gardening and looking after the family property, Elysium, and working on this Internet site, especially the wind energy pages.   Gleeson Wetlands at Clare One of my favourite places Since late 2012 I have become involved with Lions and since June 2014 I have been particularly involved – through the Lions Club – with Gleeson Wetlands. Since September 2013 I've also been removing rubbish from roadsides. (The dumping of rubbish on roadsides is similar to the dumping of waste – greenhouse gasses – into the atmosphere.) In June 2017, after being blocked from posting on a Facebook page opposing a local wind farm, I started a page explaining why I supported the project. For a short time starting in March 2018 campaigned to make cafes more responsible in handing out 'disposable' cups, that often finish up littering roadsides. In mid 2019 I started revegetating Crystal Brook's Central Park. I've written a little more on this elsewhere on this page. Move to Western Australia In 2022 Denece and I moved to Western Australia where we shared a big house with our daughter, Julia and her family. The move was decided upon because we both were becoming old and needed to reduce our driving, particularly long distance driving. In Erskine, a Mandurah suburb, we had far better public transport available to us. In Crystal Brook effectively the only public transport was a several times a day bus to Adelaide. In Clare it was only a weekly bus to Adelaide. There was no public transport between Crystal Brook and Clare. In Erskine I became involved in local environmental tasks and various other things.   Home Top Index My greatest concerns I believe that our civilisation is quite unsustainable and is heading toward a catastrophic collapse due to: climate change, (together with the closely related problems of ocean acidification, sea level rise and ocean warming); the air pollution from the burning of fossil fuels, coal in particular, that kills millions of people each year; or by one or a combination of those unsustainability problems listed by Jared Diamond in his book Collapse and repeated on my Compare Disasters page (I have added more to Diamonds list here). Such a collapse would probably include terrible wars, mass migrations, famines, and losses to our culture; at worst I can imagine a fall back to barbarism or a world dominated by religious hierarchies. Of course it is not only humanity that will suffer due to the errors of humanity; climate change will cause the extinction of many species; not, I suspect, including humanity. If our civilisation does collapse, and we sink into barbarism, then climbing back to a civilised state could be very arduous, because all the easily mined fuels and mineral resources will have gone – they have been mined out by our society. On the other hand, if our civilisation does not collapse, climate change will result in one of the greatest mass extinctions in paleontological history. Two long walks The first long walk One great experience I had was to walk from Port Augusta to Adelaide in support of a solar thermal power station for Port Augusta – to replace the coal-fired power stations that are there now. This took place during the second half of September 2012, from 2012/09/16 to 2012/09/30. One of the best things about it was the people I met. Most of them were young; late teens to early twenties, but there were six others who like me, were in their sixties. All the over-50s who did the walk From left to right: Margaret Hender (of CORENA), Pete Gorton, John Bowman, Marty O'Hare, Gaby Jung, Me (Dave Clarke), Bill Gresham, Les Webb. More than two years later I am still in touch with all of them. Note the smoke plume from the Port Augusta coal-fired power station on the left.   At the other end of the morality spectrum   Home Top Index The people who did the walk wanted to slow the damage that climate change was causing to the beautiful world that we all share with every living thing. They knew that if we keep on burning more and more fossil fuels there will be more and more damage. The Australian federal Liberal Party and Liberal politicians like Andrew Hastie may as well be employed by the fossil fuel industries. They care not at all for everyone's future. I don't have many close friends; I have come across very few people who think like me. The oldies on the walk did think like me! To meet six people who (are roughly my age and) think like me in a group of 60 or so was a revelation! They wanted to see the planet run on ethical principles! They wanted to see serious action on climate change! The walkers came from all over Australia. There seemed about as many from NSW or Victoria as there were from SA. Others came from WA, Queensland and Tasmania. How did I handle the walk? (By the way, I was the oldest by about six months.) The first day was only 16km, while the average day was around 23km. I walked the first day with no problems. On the next three days I drove a support car (I was one of the few to have my own car and trailer on the walk) about half the day and walked half the day. From then on I walked all day every day. Raised a couple of blisters on about the ninth day, but apart from that had no problems. Many of the younger people had big problems with blisters and had to take days off. We met (State) Minister (Energy and Infrastructure?) Tom Coutsantonus on the road. He was very positive about agreeing with our aims, but said that a solar power station at Port Augusta was too big a project for the State Government; money would have to come from the Federal government. (At least up to 2024 no solar thermal power station has been built in South Australia.) There was a lot of media coverage before, during and after the walk. Everyone in SA who had any interest in renewable energy, or in the Port Augusta area, would have heard about it. After two weeks we arrived in Adelaide and there was a rally that started in Rundle Park (Dr Karl Krusetnitski as the main speaker), from there to the steps of Parliament House, then on to Victoria Square. Again, a big media presence. All in all, it was a wonderful experience, and it showed me that I am not alone in caring about the world! The second long walk In 2014 a few companions and I walked from Melbourne to Canberra, taking a petition pressing for more action on climate change. That walk is described on another page on this site.   Home Top Index A fortunate life   Herat, western Afghanistan, near the Iranian border There are many ways in which I have been lucky: I was born into a loving family and my parents were intelligent and reasonably well off financially; I was born at a time when science and free thought had largely displaced superstition and religious dogmatism; I was born in one of the more economically progressive, and least religious countries in the world (Australia); I was born in a progressive and wealthy age; I was born before the great concentration of wealth into the hands of a few had corrupted the government of many nations, including my own; I was born before Mankind's impact on the world had caused the enormous harm that we are facing now; I had the good fortune to learn to question everything – to take nothing at face value. I don't think I can really take credit for this – it just happened; I have a wonderful family; While I have never been wealthy, neither have I ever been poor; I've always had enough income to cover my – and my family's – needs, with enough left over for a few luxuries such as an occasional dinner out and an annual holiday; I have never been a sheep – never cared much about following fashion, always sought to develop my own 'philosophy'; I have been lucky enough to not become an alcoholic, not take up smoking and to have quite good general health. I might just as likely have been born into an Islamic country where I would not have had access to a good education, good books, and in which I would have had religion 'pushed down my throat' from a very early age. I might have been born into a poor family in a poor country, in which case I would not have had the opportunity to get an education because I would have to spend all my time trying to feed my family and myself. I might have been born into an earlier age in a Christian country, when religion again would have stopped me from learning a scientific outlook.   Home Top Index Elysium Early morning mist, winter, Elysium Some of the trees we have planted at Elysium The family property, 'Elysium', in the Clare Valley of 'Mid North' South Australia has a total area of 46ha. We bought it in 1993, when, apart from a small pine forest, it had on it about 50 gum trees and nothing else of note. It now includes 2ha of shiraz wine-grape vines, about 5ha of olive trees, several plantations of closely spaced eucalypt hardwood trees, and a number of fruit and nut trees. Most of the remainder is now covered with open woodland that I have planted; there would have to be over a thousand gums in total. When these trees mature they will begin to be sustainably harvested for firewood. In 2012 I have noticed for the first time that there is quite a lot of natural propagation of 'my trees' happening. The area beneath and between the trees will be available for grazing animals. There are several photos of Elysium elsewhere on this site. Clare trees is a page I have written detailing my efforts at tree growing on Elysium. Tyres floating on my dam to reduce evaporation Reducing evaporation from farm dams in hot dry areas such as the Clare Valley is an important issue. This photo was taken on a frosty morning in July 2012 before the dam filled.   Home Top Index We sold Elysium, in two parts, over a few years up to 2022 due to increasing age and an inability to look after it adequately. The environment and me   Is there anything more beautiful than a tree? Of all the thousands of trees I've planted perhaps this is the one I love the most. George Monbiot once wrote "Show me an environmentalist and I'll show you a hypocrite". He had a point. Some of those who preach about the environment are personally responsible for releasing a lot of carbon dioxide into the atmosphere. For example, pop singers write songs about saving the world and then tour the world in private jet planes singing their songs. Famous environmentalists continually fly around the world giving talks on environmental responsibility. Of course we must consider the point carefully – how much good do they do compared to how much bad? Perhaps if they did not fly around the world so much they would achieve much less? My approach to the environment First I should say that I owe more than I can ever repay to my wife, Denece, for her never ending support and help. Climate change and related problems are the greatest disasters humanity has ever faced. Most Australians seem not to care enough to change their greenhouse gas producing habits. I must admit that in the past I have been content to do more about reducing CO2 emissions than most other people; partly due to Monbiot's statement mentioned above I have come to believe that being a little more responsible than most is not enough, one should do as much as one can. I would like the Earth of the future to be not greatly inferior to the one that I know and love. The list below I compiled partly because I wanted to make a list for my own interest, and partly in the hope that it might give others some ideas that they may not have already thought of. Our solar photovoltaic panels and solar water heater at Crystal Brook A small car with occasional use of a trailer will produce less CO2 than a big car. This Mazda 121 has only a 1300mL engine, can comfortably tow a trailer with a 500kg load, and as of April 2011 has done 194 000km and is still going strong. Quality is more important than quantity! Revegetation we have done on one of many Crystal Brook roadsides Some of the native eucalypt trees that we have planted on our property, 'Elysium'. At Elysium our hot water comes from this solar panel in the warmer half of the year and from the wood-fuelled heater in the background when the sun is not shining; no fossil fuels needed. More of the eucalypts that we have planted at Elysium. Self-sown leucoxylon in the foreground, behind those are camaldulensis, cladocalyx, and globulus; in the background are Pinus radiata that were on the property before we bought it. Wattle Point wind farm on Yorke Peninsula. Wind power is not 'the answer' to greenhouse/climate change, it is 'a small part of the answer'. I do what I can to support wind power. The closest wind turbine to my home is at Clements Gap Wind farm 14km away. My efforts to become more environmentally responsible I have listed many actions that governments, industry, and individuals can take to limit their greenhouse impact in my page on What should be done? Of course I try to follow my own suggestions. Trees Trees take carbon dioxide from the atmosphere. Trees on roadsides With help from family and friends, I have planted trees on all available roadsides within several kilometres of my home. (Photo at right) Open woodland I am planting trees on the family property, ' Elysium' Controlling feral plants I have killed most of the feral pepper trees along the creek at Bowman Park and some other areas around Crystal Brook to allow native trees to recover. I have cleared feral pine trees on part of Blyth Road and the Riesling Trail in Clare.   Home Top Index Cellar I had a cellar built at Elysium in July 2006. This used a large amount of concrete which is not environmentally friendly, but the energy savings in the long term, due to there being no need to heat or cool the cellar, will outweigh the initial environmental cost. Transport There are a number of things that can be done to minimise ones greenhouse impact. Minimise car use I try to only use a car when there is no reasonable alternative and walk or ride a bicycle when I can. Use a small car rather than a big car Use a trailer when the car is not big enough. (Photo at right) Use public transport When walking or cycling is impractical and when available. (There is very little public transport in my area.) Avoid flying Not one of my strong points! Electricity We used to buy our electricity from AGL, but since they, like the other two big electricity retailers (Energy Australia and Origin), lobby the government against renewables, we changed to Diamond Energy; I try to be conscious of minimising our use of electricity all the time. Solar water heater We have had a solar water heater on our house for about 30 years, and have more recently installed one at Elysium. They have not only saved lots of carbon dioxide, but have saved us a bucket of money. (Photos at right) Solar photovoltaics We installed 1 kW of panels at our home on 2006/02/08 (either the second or third PV in Crystal Brook, photo at right), another 1.5 kW at Elysium on 2011/01/18, paid for 5 kW more to be installed on our daughter's house on 2011/01/25, paid for about 3.4 kW on our son's flat in April 2011, and put another 5.2 kW on Elysium on 2014/02/18 (a total of 16 kW). In March 2021 I had another 5.94kW installed at Crystal Brook making the grand total 22kW. Green electricity We buy 100% green electricity.   Home Top Index Heating/cooling Wood fire heating We rarely use any other form of space heating. Evaporative air conditioning We only use the more energy consuming heat-pump (reverse cycle) air conditioning at the rare times when it is hot and the humidity is too high for the evaporative air conditioning to work. Use natural heating/cooling We try to minimise the need for home heating and cooling by using passive methods of temperature control, such as insulation and opening and closing windows at appropriate times. In winter we open the house at the warmest time of day; in summer we open the house in the coolest time of day. Rain water We catch most of the rain that falls on our roof. This saves a little water from the over-taxed Murray river. An effort to change the World A citizen's participation in democracy should not be limited to voting. I have heard advice that there is no use worrying yourself over things that you cannot change; this is good advice, but it should not stop you from trying to change those things that are very difficult to change. If you want something done, do it yourself. If you try you may fail, if you do not try you will certainly achieve nothing. If you are unwilling to try, why should others do so? Letters to newspapers Letters to politicians I have stood for parliament twice Maintaining this Internet site, which is largely devoted to environmental matters, particularly wind power Participating in a 320km walk from Port Augusta to Adelaide in support of a solar-thermal power station at Port Augusta Participating in a 740km walk from Melbourne to Canberra to press for action on climate change from our federal government Ethical investments We are careful to place our savings where they will be used ethically. For example, we took most of our cash savings from the ANZ bank, because it was loaning money to coal miners, and placed them with the People's Choice Credit Union. Cleanup I am trying to get the message out about climate change at the same time as cleaning up local roadsides. Refrigerator/freezer A minor thing, but everything counts – we replaced an old refrigerator and freezer with modern and more energy-efficient ones. Not only has this reduced our greenhouse footprint, but it will save us money in the long term. Total energy consumption Peter Seligman, in his book "Australian Sustainable Energy – by the numbers" gives total energy use in Australia as 200 kWh per person per day. Of this 42% is electricity (84 kWh/p/d). My wife and I use a total of about 12 kWh/day electricity (three meters, figures for 2010); this is 100% green power so would equate to about 13 kWh/day at the generators (wind or hydro) allowing for transmission losses. (If we used fossil fuel generated power then the total energy in the fossil fuels burned to supply our 12 kWh/day would be about 53 kWh/day (12 × 1.1 / 0.25, allowing for transmission losses of 10% and conversion efficiency of 25%).   Home Top Index CO2 production calculation I have used my Greenhouse impact calculator to calculate how much CO2 I expect my wife and I to be responsible for releasing into the atmosphere in 2006. This section was written in February 2006 and updated in August 2006. I recommend this exercise to everyone. I learned a lot from doing it. (Most of the figures are at least to some extent estimates; of course now [December 2012] they are dated.) 2006 Activity kg CO2 kg totals Holiday in Vietnam Air travel 4600 Internal travel 1000 Vietnam total 5600 Holiday in Western Australia Air travel 840 Car travel 720 WA total 1560 Use of cars Toyota Corona 500 Mazda 121 1800 Vehicles total 2300 Electricity consumption 100% green electricity At home 0 At Elysium 0 Elec. total 0 Building concrete cellar Cement 4500 Steel 1000 Cellar total 5500 Miscellaneous (Guess) 500 500 Gross total 15,460 Electricity abatement Photovoltaic panels 240 Abatement credit total 240 Net total 15,220 = 15.22 tonnes   Home Top Index Note on the cellar in the table for 2006, above. We built a large cellar based on a buried concrete tank in 2006. Producing the cement and steel for the cellar released something like five and a half tonnes of CO2 into the atmosphere. My page on Wind power problems discusses the CO2 implications of cement manufacture a bit more and contains some references. This is a big, one-off, impost on our greenhouse gas production, but should cut our future annual greenhouse production by reducing the need for air conditioning. It will also provide a large cool storage space that will not require energy and therefore will not be responsible for producing CO2 for many years. There is more on this cellar in the Australian section of this site. 2007 Activity kg CO2 kg totals Use of cars Honda Jazz 1800 Mazda 121 600 Vehicles total 2400 Electricity consumption 100% green electricity At home 0 At Elysium 0 Elec. consumption total 0 Miscellaneous (Guess) 500 500 Gross total 2,900 Renewable electricity credits Photovoltaic panels 240 240 Net total 2,660 = 2.66 tonnes Notes on the 2020 table Obviously the table on right was created more than a decade after the 2006 and 2007 tables. In that time enormously more information had been published on the Internet and, hopefully, it is more complete, more accurate and, again hopefully, my understanding has improved. At the same time passenger flights have increased their fuel efficiency. One very interesting page I came across is that on BBC Science titled Climate change: Should you fly, drive or take a train? It was published on 2019/08/23. Importantly it not only gives the CO2 emissions from flight, but also the non-CO2 emissions such as oxides of nitrogen. The BBC Science article gives the following emissions figures: Flight type CO2 emissions non-CO2 Total Domestic 133g 121g 254g Long haul 102g 93g 195g   2020 Activity kg CO2 kg totals Holiday in Western Australia Air travel 1,950 Other travel 100 WA total 2,050 Use of cars Honda Jazz 2060 Mazda 121 700 Vehicles total 2760 Electricity consumption 100% green At home, 1440kWh 0   At Elysium, 1807kWh 0 Elec. total 0 Miscellaneous (Guess) 500 500 Gross total 5,310 Electricity abatement Elysium, 9,052kWh 4,526 Crystal Brook, 479kWh 240 Abatement credit total 4,766 Net total 544 = 0.544 tonnes These tables show how much impact holidays involving air travel have on one's greenhouse gas production. The holiday in Vietnam for two people, at 5600kg of CO2, was 36% of our gross greenhouse gas production for 2006, the holiday in WA was 39% of our gross for 2020.   Average annual CO2 production Who How much CO2 released (tonnes) Average global citizen 1 Average citizen if climate change is to be stopped 0.3 Average Australian household is directly responsible for 14 Per capita Australian CO2 including all sources, eg. mining, manufacturing, office buildings, commercial transport, etc. 27 My wife and I (each) 2006 7 My wife and I (each) 2007 0.8 I have read that the average global citizen is responsible for releasing one tonne of CO2 into the atmosphere each year (and that this must be reduced to 0.3 tonnes if climate change is to be limited to a acceptable level). At an average of three tonnes for each my wife and I for the three years calculated above, like most Westerners, we are well above the average, and we consider ourselves to be careful! The average Australian household is directly responsible for about 14 tonnes per year, but I believe that if each person's share of the CO2 from things, like manufacturing and mining, etc. was included, the total would be around 27 tonnes per Australian per year. I have only considered the CO2 that my wife and I are directly responsible for here. The abatement for the trees that we have grown is calculated elsewhere on this page.   Home Top Index CO2 abatement calculation I have used my Greenhouse impact calculator to calculate the abatement from the tree plantings on our family property, Elysium. This calculation was done in February 2006. Plantation No. trees Ave. mass Annual % increase kg CO2 Bore 150 100 40 5500 One Hectare 600 40 40 8800 Bog 100 60 40 2200 Dam paddock 150 5 200 1375 25 300 40 2750 New paddock 300 1 250 690 Open Woodland 400 1 250 920 80 300 40 8800 Totals 1805 31 035 Notes on the table I have calculated that the native eucalypts that I have planted increase in mass by about 200% per year from the end of the first year to about year 5, then increase by about 100% per year to year 10. Where I have used the relatively low 40% annual increase rate the trees are close enough together to compete fairly heavily. These figures are obviously approximations. These calculation do not include trees and shrubs that I have planted on roadsides; nor the feral pepper trees that I have killed (they will release CO2 to the atmosphere as they rot, but then they will eventually be replaced by native trees). The CO2 absorbed by the 'Open Woodland' planting will increase quickly as more trees are planted and their average mass increases. These trees are spread over about 35ha. What I have learned out of this exercise It has surprised me that the 1800 trees I have planted at Elysium are probably only taking twice as much CO2 from the atmosphere as my wife and I will be putting into the atmosphere in 2006. A lot of land, time and expense has been devoted to these trees. This shows how hard it can be to balance one's greenhouse gas impact and convinces me more than ever that our society should be taking greenhouse/climate change much more seriously. Buying 'green electricity' I have also been surprised at how much my personal greenhouse impact was reduced by subscribing to green electricity. Buying 630 kWh of electricity (at Elysium, from AGL) at 5.5c/hWh, a total of $34.65, reduces my annual CO2 production by 700kg. This would have to be by far the cheapest reduction that I have managed.   Home Top Index Influences Positive influences   Books on ethics I believe I've read most of the books on ethics in the local Clare library; I periodically look through the section to see if there is anything new there. Of course I cannot list all those people who have influenced me (apologies to any I have missed), but some, in no particular order, are: My parents My father and mother instilled in me a basic feel for justice, good, decency, honesty, etc. My mother tried to make me religious (Methodist), it didn't work; but my parents tempered their religion with ethics. I was fortunate in having parents who always, at least so it seems to me now, considered my interests and needs at least on a par with their own. My wife Denece, my son Ken, and daughter Julia I owe Denece more than I can say. Ken is one of the few people I feel I can argue a moral, scientific or philosophical issue with. Julia helps to keep me in touch with some big sections of society and ways of thinking that I might otherwise neglect. Socrates, Plato, the ancient Greek philosophers in general The first recorded reasoned thoughts about ethics. Every thinking person in the West is influenced by these people, I was especially impressed by an early reading of Plato's Republic.   Down the last big hill on the Tumbarumba road to Tumut Melbourne to Canberra walk Walking companions I walked from Port Augusta to Adelaide in support of solar thermal power in 2012 and from Melbourne to Canberra for climate change action in 2014. The wonderfull people with whom I walked have all influenced me; several have remained good friends. (I don't want to list any here because I don't know where I should stop on the list.) Ian Roberts and Des Menz Two Clare locals who are inspirational in their environmental and social efforts. Sandy Dodds A friend with whom I have had many interesting discussions on ethics, general philosophy, science, government, and other subjects. Zac Sibenaler, Don Armstrong, Bob Read and Mike Cobb I was privileged to work with these honest, intelligent, ethical and kind men. At one time or another they were all my bosses. They didn't go very high in the public service because they held honesty and loyalty to the people below them more important than sycophancy and ambition. Bertrand Russell Mainly through his book, A history of Western philosophy, but also though humanitarianism and his example in pacifism. Gandhi, Mohandas Karamchand (Mahatma 'Great-Souled') Through his example, his 'civil disobedience' and peaceful protest, his way of achieving great things without hurting anyone. If only politicians tried to follow Gandhi's example in getting things changed without blood-shed.   Home Top Index Peter Singer Through his books: Animal rights, How ethical is Australia, How are we to live?, One World: the ethics of globalisation, Practical Ethics, The Most Good You Can Do. The Dalia Lama, Bstan-'dzin-rgya-mtsho Through his book, The Art of Happiness. He seems to have thoroughly developed the Buddhist art of dispassionate analysis of life. Paul Robeson Through his long and courageous stand for civil rights for his people and for what he believed to be right and his use of patient, peaceful protest. Jesus He had some great ideas. Anyone raised as a Christian in a predominantly Christian country cannot help being influenced by Jesus. Christianity and its successor, Islam, were largely disasters; they stopped people from thinking clearly and freely and they lead to many wars and enormous cruelty and injustice, but Jesus should not be held responsible for this. Saint Francis of Assisi For his early (for the West) realisation that other animals are our brothers The great early scientists, and science in general Too many to name; where would we be without them, and it? Some are named in Milestones. They had a lot to do with saving us from the dictatorship of monolithic Christianity. Charles Darwin By explaining organic evolution so well that no reasonable person could doubt its truth he helped to free the world from the God delusion. (God was no longer needed to explain the complexities of life on earth.) Alfred Russel Wallace also explained organic evolution; his work and Darwin's were presented together to the Linnaean Society of London on 1858/07/01. I've read Darwin's On the Origin of Species and a book on Wallace titled The Malay Archipelago. Siddhartha Gautama (Buddha, Buddhism) Like all the great religions, Buddhism includes a lot that is nonsensical, however there is a lot that is admirable in Buddhism. Terry Lane An exceptionally insightful, well informed, and intelligent ABC radio interviewer; now retired George Monbiot A journalist dedicated to honesty, truth and a future for the Earth. Writes for the UK Bulletin and keeps an excellent Internet site. Jonathan Neale Through his expose in A People's History of the Vietnam War; one of the great crimes against humanity of recent years.   Home Top Index Negative influences Religion I was brought up a Methodist Protestant Christian. I gradually became aware that there was absolutely no evidence for the existence of a God (or gods). From there I went on to realise that religion had resulted in huge injustices, cruelties and delays in the progress of society. Religion is delusional and delusions are a fault that we cannot afford in the twenty-first century when there are so many threats to our shared planet. Hitler, Stalin, George Walker Bush, John Winston Howard, Anthony John "Tony" Abbott, Scott Morrison, Vladimir Putin and Xi Jinping. Twisted men who believed that power and wealth are sufficient for greatness, that war can be good, that governments can limit the freedom of speech and the press when they choose, that people can be locked up indefinitely without trial if that is convenient, that immoral means can be justified by the end (which may never be achieved), and that the only value the environment has is the wealth that can be got from it. They were (or are) willing to damage the world and trample people's rights for what they saw as the short term 'good' of their class or supporters, or for their own glory. (Doctor) Sarah Laurie Sarah Laurie was for a time the general practitioner I consulted in the small town that we both lived in, Crystal Brook. After she left general practice she became convinced that wind turbines made people sick. She searched for 'evidence' connecting wind turbines with illness and apparently believed whatever she could find. It seems that she chose not to question what she found. At the same time I was supporting wind power (and other renewable energy technologies) because of the undeniable connection between the burning of fossil fuels and anthropogenic climate change. Ms Laurie very successfully spread her delusional belief to anyone who would listen in the period from about 2010 to 2014. Since then, of course, the nonsense has gone into the dustbin of history. Ms Laurie's delusion-based campaign was a personal lesson to me on how someone can go badly wrong by looking only at the 'evidence' that supports one's beliefs and do great harm by conscientiously following a false belief.   Home Top Index   This section added 2022/02/09 Information sources While much of my information comes from the books I've read, the people I've listed as positive influences and the Internet generally, there are a few specific sources that I've found to be particularly reliable and important: The ABC (Australian Broadcasting Commission); Google News Alerts (although since at least mid 2021 I've been disappointed with Google search; it misses a lot; Yandex seems better); The Guardian; Open NEM to keep track of Renew Economy; progress toward 100% renewable energy; the Sydney Morning Herald; The Conversation; Wikipedia. On the other hand I've found the Murdoch media, in particular, to be highly biased and unreliable. My affiliations I write these pages with a completely free hand. I am not beholden to any company, lobby group, political party or government; however as of August 2011 I did have the following affiliations: Life member Trees For Life, South Australia; I have financially supported the Australian Greens and was for many years a member of the Australian Democrats; I have given donations to, and continue to support, various environmental conservation groups as well as general charities; I am a supporter of 'Death with dignity'; I have sold limited rights to some photos, including to wind farm operators;   Home Top Index Books Some other of the books that have influenced my way of thinking are noted above under Influences; others are below - in no particular order... A Field Guide to Rocks and Minerals (1960) Frederick H. Pough; I believe that this was the first book I bought on mineralogy/geology. To some extent it would have helped ignite my interest in the subject that was to become a big part of my life. Fortunes in Minerals Ion L. Idriess (1889-1979); this was another early book I read on mineralogy. (I read many of Idriess's books. In my opinion he was an outstanding author on Australia in the period of his lifetime.) Mineralogy: An Introduction to the Study of Minerals and Crystals Kraus, Hunt and Ramsdell; from which I learned much about mineralogy and, in particular, qualitative chemical analysis (at my home). Larousse Encyclopaedia of Astronomy Probably about 1960 edition. I learned a lot from this book. Astronomy has moved on to the point of almost being unrecognisable since then. The Challenge of Things: Thinking Through Troubled Times A. C. Grayling. I was struck by how much Anthony Grayling and I had in common in the things we thought about and wrote about, and how much our opinions and concerns aligned - also by how far greater and deeper his knowledge of his subjects was than mine. Ethics in Practice: An Anthology Edited by Hugh LaFollette, Blackwell Philosophy Anthologies Hiroshima Nagasaki: The Real Story of the Atomic Bombings and Their Aftermath Paul Ham. Giving a detailed background of the events that led up to the atomic bombing of Japan. It holds that it was not the nuclear bombing of the two cities that ended WW2. His Dark Materials A trilogy novel written by Philip Pullman: apart from being a very good read, it gives a fascinating and novel interpretation of the Judaeo-Christian mythology. It is the only story I've ever come across that explored the possibilities in the concept of the overthrowing of God. Published by Scholastic Children's Books. (Had it been written about Islam rather than Judaeo-Christianity it would probably have resulted in the burning of embassies.) The Prince Niccolo Machiavelli explored the possibility of divorcing politics from ethics; John Howard and Kevin Rudd could have taught Machiavelli a thing or two. Principles of Physical Geology Arthur Holmes; I bought this book out of interest and later found that it was required reading in a summer school in geology I attended at the University of Tasmania in about 1971.   Home Top Index The Coming Famine: The global food crisis and what we can do to avoid it Julian Cribb; One of the aspects of the end of the current civilisation is the unsustainability of present farming methods and the increasing demand for higher quality food. Philosophy (Beginners Guides) Peter Cave; Forces questioning of most of the things that one thinks one knows   Danang kids How many kids like these were killed in the Vietnam War? Memoirs of War: The Central Highlands Le Cao Dai; A North Vietnamese Journal of Life on the Ho Chi Minh Trail 1965 – 1973; which I would highly recommend to anyone wanting a glimpse into the Vietnam War from 'the other side'. Guns, Germs and Steel, and Collapse Jared Diamond; every thinking person should read Collapse because of its applicability to the present times. A People's History of the United States Howard Zinn An alternative, and I suspect, a much more honest and human history of the USA; highly recommended The God Delusion, The Blind Watchmaker and The Greatest Show on Earth Richard Dawkins God is not Great: How Religion Poisons Everything Christoper Hitchens In the Footsteps of Gandhi Catherine Ingram; discusses a number of people who have adopted Gandhi's methods of non-violence to bring about change Meditations Marcus Aurelius; His Meditations make him sound like a man who I could easily have liked and respected.   Home Top Index Revegetation About 1988 I started planting native trees along roadsides around my home town, Crystal Brook. Crystal Brook area Trees along Binney Road, Crystal Brook Bowman Park. Most of the lower trees on the left are feral pepper trees The roadside planting I did was the south-western side of Greig Road north-west of Frith Road, photo at right. I think it was probably the next year that I planted the other side of Greig Road. Other roads planted were Nurom Road between the creek and highway, Frith Road, Darbon Terrace, (and the apparently unnamed road on the western side of town that run between Greig Road and Darbon Darbon Terrace), parts of Huddleston Road east of the cemetery, Bowman Park Road, Gadd Avenue south-west of town, and Brook Park Lane. In the first year I planted Australian native trees that were mainly endemic to Western Australia (along the south-western side of Greig Road); after that I only planted species that were endemic to the local area. In mid 2019 I started revegetating Crystal Brook's Central Park. I've written a little more on this elsewhere on this page. Feral pepper trees Starting about 2002 I began trying to remove feral pepper trees along the Crystal Brook. At first I cut and swabbed trees upstream of Lions Park, not very successfully. Someone else later did more work on these trees. In August 2003 I started killing pepper trees along the Crystal Brook at Bowman Park. I kept the local council (Port Pirie Regional Council) fully informed of what I was doing. To say the least, Council has not been supportive, although they have agreed that the pepper trees should be removed. I have discussed this in my jottings page. I intend to continue this project until all the pepper trees along the creek in Bowman Park are dead. When the pepper trees are gone the native red gums (Eucalyptus camaldulensis) will be able to take their place. Many red gums along the Crystal Brook have suffered greatly from a lack of water in recent years. Killing the pepper trees will make many thousands of litres of groundwater available to the gum trees each year. The method I have used to kill the pepper trees is drilling and injecting with Garlon. This is done by drilling 6mm diameter holes at least to the cambium layer at about 5cm spacing around the trunk of the tree and then immediately filling the holes with neat Garlon. The holes should slope downward and should be as close to the base of the tree as possible. I have been informed that glyphosate is just as effective as Garlon, but have not yet tested this. Clare area Getting ready to ringbark one of the larger of the aleppo pines in Spring Gully Conservation Park About 2000 my son Ken and I killed all the feral aleppo pines (Pinus halepensis) in the section of Spring Gully Conservation Park near the spring. In early 2005 I got permission from the Clare and Gilbert Valleys Council to begin removing feral trees and revegetating with natives along a length of the Clare to Blyth road. The section I am working on runs from the top of the hill overlooking Blyth (Lat. S33.84039, Long. E138.55978) about a kilometre down the hill (to Lat. S33.83981, Long. E138.54965). Blyth Road east of this point is crowded with ferrel trees, mainly aleppo pines, but also olive trees and others; there is very little native roadside vegetation remaining between Scobie Road and the top of the hill. There is a lot of native vegetation remaining along the section that I'm working on, but there is also many ferrels: mainly aleppo pines, olives and briars. As of April 2006 I have killed most of the aleppo pines. They are easy to kill. The smallest are easiest handled by pulling them out, larger ones can be cut off at ground level, and the biggest can be ring-barked.   Home Top Index Olive trees are much harder to kill. Again, the smallest ones can be pulled out, slightly larger ones can be dug out with a pick. Cutting larger trees and immediately swabbing the stump with glyphosate might kill them. I am intending to experiment with drilling an injecting (as used against pepper trees, above) in future. Gleeson Wetlands A small part of the Gleeson Wetlands 2017/05/31 Starting in June 2014 the Clare Lions Club took part responsibility for looking after the Gleeson Wetlands. I have spent many hours, and obtained great satisfaction, working at killing weeds, planting, mulching and generally looking after the gardens at the Wetlands.   Home Top Index   This section added 2017/07/07 A purpose   Boco Rock Wind Farm, New South Wales Debunking the lies about wind farms has given me a purpose – see the main text. As I have written elsewhere in these pages I do not believe that there is any ultimate purpose to life apart from that forced upon us by our genes. No open-minded thinking person can place any credence on religion. Yet it seems to be human nature to crave a purpose, so what purpose can one give to one's life? Apart from the day-to-day necessities of living, can we feel that we have some value? How can we have any self-respect if we see our existence as useless and pointless? In the first few decades of our lives we are occupied with our education, finding our place in life, and probably finding a partner. Once we have children (supposing we are among those who do have children) we have a purpose in giving them the best possible start in life that we can. (Abraham Maslow produced a hierarchy of needs, which is very relevant to this subject, but too complicated for me to go into on this page.) But when our children have left home and become independent, and supposing that we are sufficiently financially secure that our immediate needs are taken care of, what purpose remains to life? My musings on ethics and compassion have convinced me that I can and should make an effort to do what little I can to make the world a better place in my remaining years. This led to my page on contribution. (I have written at some length about my general background elsewhere on this page.) I am convinced that climate change and the related problems of ocean acidification, sea level rise, ocean warming and the air pollution from the burning of fossil fuels that kills millions of people world wide each year are the greatest threats facing our shared world. I also believe that humanity could greatly reduce the harm that we are doing to the planet with relatively little effort. Yet we are not making that required effort, and the Earth continues to suffer from our misuse. So I feel that my primary purpose at this point of my life (2017) is to do what I can to try to get action on greenhouse emissions. At the same time I will do what I can to try to improve my local environment. It happens that the region in which I live is well suited for wind farms, which reduce greenhouse emissions by displacing fossil fuel generated electricity. Some of the local wind farms that are present have been built with little or no opposition, others have had determined and vocal opposition. Many of the arguments put forward by the opponents are ill-informed, dishonest and misleading while some of the fears are so out of touch with reality as to justifiably be called delusional. No one else in my region, apart for those who are building the wind farms, have made much effort to try to counter the misinformation from the wind farm opponents, so I have found a purpose in doing so myself as an independent voice. On other pages on this site I have written about wind power in Australia, have discussed why I support a proposed local wind farm which is suffering from selfish, short-sighted opposition and mused on the contrast between the opposition movements to wind and to coal. I have largely concentrated on the problems relating to climate change; one can't do everything, one must choose one's battles, but I try not to loose sight of the great many other problems and injustices that we see all around us. Apart from action on climate change, up to when Denece and I moved to Western Australia in February 2022, much of my spare time has been put into improving Gleeson Wetlands in Clare, Crystal Brook's Bowman Park and Central Park and cleaning up rubbish on roadsides. After our move to WA in February 2022 what I would think of as my productive time was spent on removing weeds from public areas, picking up rubbish, and writing these pages. I have continued to write letters to newspapers and politicians, financially support good causes, and encourage local councils to do the things it seems to me that most need to be done. I've written a short summary of my other activities in WA on the same page as the weed controlling.   Home Top Index Then there's blood donation; as of early 2024 I'm on record of donating whole blood or plasma 149 times. It would actually be more because the blood service's records only go back a couple of decades or so. The best thing I've done? It is obvious to all but the intentionally blind and the grossly ignorant that climate change and related issues are the greatest threat facing the future of our shared environment. The development of wind power in SA was important in reducing the greenhouse emissions that drive climate change. I believe that I had a significant part in informing the public of the truth in pages such as Wind health, Wind turbines save lives and many others. I've also exposed those who have blatantly lied about wind power, such as individuals including a number of politicians, Connie Bonaros for one, and groups like Stop These Things. The lies about wind power continue in 2024 with people like Andrew Hastie, federal member of parliament for Canning, where I was living at the time.

A week's electricity generation in SA, December 2022
The graph above records that 104.5% of South Australia's power demand was filled by renewable energy in the week 11th to 18th December 2022 (excess energy was exported to Victoria). For the last day in that period the figure was 114%. I've been actively supporting renewable energy, wind power in particular, since at least 2003. SA, where I have lived most of my life, has lead the nation in the adoption of wind power from 2005 up until at least 2018. While Victoria has taken the lead in total wind power since then, in 2022 SA was still well ahead in percentage of wind power and percentage of total renewable energy too - see above graph. From around 2010 to 2014 there was a serious attempt by wind power opponents to claim that wind turbines caused ill health. One of the leaders in this delusional campaign was for a time my GP and lived about 12km from me. Image from Open NEM, 2022/12/16

Trolls My advocation of wind power, and my public contradicting of those who lie about wind turbines, have unsurprisingly attracted the attention of some trolls. While these are malicious people who insult and abuse, they are in fact of some use.   Home Top Index If I was substantially wrong in my writings I'm sure that there would be intelligent people telling me so (I do correspond to many well informed people who provide very valuable information). The fact that my critics are almost entirely ignorant low-life, who typically hide behind false names, suggests to me that I must be largely on the right track. As mentioned above, my greatest concerns are climate change and related problems. While the two long walks I have done were aimed at getting action on reducing Australia's greenhouse emissions, I suspect that my participation there had very little impact. Where I have had a significant impact is in providing factual information about wind power and exposing the lies of those who have dishonestly opposed its development. Being independent of the wind industry gave my writing more credibility than the information provided by the industry, because that could be perceived as being biased. An Internet search on many subjects relating to wind power will find one or another of my pages (I'd suggest using search engines other than Google). Not only have my pages given the public access to facts, but they have given opponents an incentive to take more care in their claims, or be exposed as delusional or liars. By showing wind power to be generally environmentally friendly, harmless to health and welfare (unlike coal and other fossil fuels), and effective in reducing greenhouse emissions, I feel I have achieved something in the fight to limit anthropogenic climate change. As I have written in more detail elsewhere, putting 5kW of solar panels on a roof could save 8 tonnes of carbon dioxide each year but helping to get a wind farm built will save several hundred thousand tonnes of CO2 per year. Having good intentions and trying to do good is great, but to feel that you have achieved some significant good is very satisfying. Crystal Brook Central Park In mid 2019 I started revegetating an area of neglected land in the middle of Crystal Brook. This had to fit in with my continuing efforts to look after Bowman Park, near Crystal Brook and Gleeson Wetlands in Clare. The land in the middle of Crystal Brook had for many years been under the control of the body that controlled the railway line that runs through it. More recently it has come under the state Department of Planning, Transport and Infrastructure. Both organisations have provided some resistance to the improvement of the land, but I have made progress in spite of this. Until very recently I have called the land the 'railway reserve'. I intend calling it in future Crystal Brook's Central Park. Western Australia In February 2022 Denece and I moved to WA where I have adopted a project to remove the invasive weeds fleabane, false onion weed and several other species in and adjacent to the parks within about a kilometre of my home. In mid December 2022 I believe that removing the onion weed is achievable, full success with fleabane is more in doubt (it is very widespread on streets and gardens and seeds are moved around by the wind); I continue trying. In WA, in addition to the weed projects mentioned above, I have worked at other activities with the aim of improving the local environment. Trishaw rides Then there's trishaw rides. The photo on the right, taken 2024/10/23, shows me piloting a Malaysian family on a electric assisted trishaw in Mandurah. At the time the Mandurah section of an organisation called Cycling Without Age ran free trishaw rides for anyone interested, although they were aimed mostly for people who had trouble walking.

This section added 2021/03/07 Minimalism   Our tiny mobile house While many people our age bought huge camper vans or caravans worth tens of thousands of dollars and weighing tonnes, we bought this tent trailer for $3,000. The whole thing, trailer and all, weighs about 400kg. We have since decided that we don't need the annex; by leaving it behind we can save about 13kg and by not erecting it we can save a quarter of an hour of setting up time. If the weather becomes too inclement for camping we stay in some other accommodation for a day or two.   The mobile camper trailer - very tiny house - folded up for the road. A Honda Jazz has towed it many thousands of kilometres and several times over the Great Dividing Range with no problems, and uses about 7 litres of petrol per 100km while towing. I think my wife and I have to some extent practiced minimalism for many years. For example, when we moved from Adelaide to Crystal Brook we bought a run-down and partly renovated hundred year old house for about a quarter of the typical house price of the time. So we didn't need to saddle ourselves with a mortgage that would take many years to pay off. We fixed up the old house over a decade or more and extended it when our kids were growing up. As much as we needed; no more. But it was a program on Netflix by Joshua Fields Millburn and Ryan Nicodemus that alerted me to the concept and word 'Minimalism' that moved me to write this section. Joshua and Ryan argued that everyone can be happier if they downsize their houses, minimise consumption and the collection of unnecessary 'stuff'. The more you consume the more you have to work to pay off the costs of your consumption and the more stressful is your life.   Home Top Index Very relevant to minimalism in this sense is the tiny-house movement. This has been a reaction to the huge and continually growing cost of buying a home - often involving the taking on of a mortgage that will take 30 years or more to pay off. People in the past had, and people in third world countries have, much smaller and simpler houses. People in the West have been saddling themselves with bigger and bigger houses that come with bigger and bigger debts. My wife and I have also been unknowingly involved in the tiny house movement; we have a shack where we spend quite a bit of our time. The living area is 36 square metres (although there is also a cellar). Our cars have also been minimalist. Since our kids have grown up and left home we've had, consecutively, a Mazda 121 and two Honda Jazzes. When the kids were at home we had a Toyota Corona. All of these cars were the smallest that were practicable for our needs. We use a trailer when we need more carrying capacity. As I've noted elsewhere on these pages, increasing income beyond a level sufficient for covering one's needs does not increase happiness. Joshua and Ryan argued that having more than enough actually reduces our satisfaction with our lives. (Relevant here is my page on the greed of the corporate bosses.) Of course, apart from the mental benefits that come from living minimally, we must have saved a lot of money over the years, several hundreds of thousands of dollars I would think.   This section added 2020/10/02 Achievement I think that for most of my life I have aimed at achieving something or other rather than just passing the time. That has not been a continuous thing, I don't think anyone could say that I am obsessed with achievement (although there probably were times when I did become obsessed - for example when I was writing my books), but there was usually something that I was trying to get done, whether it was building a boat, building a shed, building one or another astronomical telescope, learning to facet gemstones, getting native trees established on roadsides, exposing the lies of people who don't want wind farms, combatting those who oppose action on climate change, or whatever.   I don’t understand why anyone would prefer to do some pointless pursuit such as golf or lawn bowls, in which nothing is achieved, instead of an activity, any activity, that actually results in something being achieved? But very few other people seem to feel the same way! And very few people seem to feel any desire to improve our shared environment, while many make great efforts to improve their private spaces. (See my page on contribution.) These things are mysteries to me. This continues in my old age. When I work at the Gleeson Wetlands or Crystal Brook's Central Park the work that I decide to do is based on what seems to be the work that will achieve the most for the amount of time and effort available. Perhaps the drive to achieve has even increased in my old age; I feel the need to use the time and energy left to me productively rather than wastefully. If I didn't contribute something to society in my declining years I would feel that I was useless. I have often been disappointed in he lack of community spirit that I see demonstrated in many of the public gardens in towns around my home state, South Australia. So much could be done by even one or two volunteers if they were willing to put in a few hours a week rather than wasting their time in unproductive pursuits such as golf or bowls (An example at Maitland, Yorke Peninsula). Certainly the drive for achievement does not occupy my mind all the time, when I am tired in the evening I usually relax in front of the television. Like most people I enjoy a relaxing touring holiday.   Home Top Index   This section added 2021/11/21 The inevitable - ageing Toward the end of 2021 my wife and I decided we needed to minimise our driving as well as reducing our responsibilities and work load. We decided to move to Mandurah in Western Australia where we can share a house with our daughter and her family and use public transport far more than we are able to at present. The move involved selling two properties in South Australia and disposing of hundreds of books and other odds and ends. The end My wishes regarding the tail end of my life might as well be recorded here as elsewhere. If I ever mentally deteriorate, or suffer an injury which causes loss of mental function, to the point that I am no longer recognisably the same person, I want to be euthanised. If that is not legal, I do not want to be kept alive by any means whatever; if I am not capable of feeding and looking after myself, I want to be allowed to die. I do not want or intend to go into a nursing home. If I become incapable of looking after myself I intend to kill myself. My current thinking is that I will do this by placing a plastic bag over my head and injecting into this bag a flow of a biologically inert gas (such as nitrogen, argon or helium). I believe that the inert gas works to displace the carbon dioxide which would otherwise build up and cause the feeling of suffocation. Anyone killing themselves by this means, I believe, will slip into unconsciousness in a very few minutes and die shortly after. I have enquired about donating my body to the University of WA body donation program in the hope that it can be of some use in research or teaching. Also relevant are my thoughts on death, especially the sections on Why might one want to die and What personal reasons do I have to seriously consider ending my life?. Disposal of my body On death I would like my body, which will have ceased to be me in any meaningful sense, to be treated and disposed of in the most environmentally responsible manner possible. I do not want to be injected with any preservatives (no embalming). I would like to be buried in a shroud only; I consider a coffin to be an ntirely pointless waste of resources. I do not want any show about my funeral and I'd prefer it to be attended only by close family; if it can be made into an enjoyable occasion, so much the better. I certainly do not want any religious drivel spoken at any ceremony that there might be. My web site: comagecontra.net I'd like my Web site to be kept going; I have hopes that it might do some good after my death. Funeral Instructions, apologies to Martin Jabez Leese – "No fuss or bother. Above all, minimal cost. If you can get away with digging a shallow hole in the garden at Elysium then do so, I might do the plants some good. Alternatively, have me stuffed and placed in your living room as a conversation piece. (If I am holding a tray, people can put things on me.)" From Pithy sayings; there is great wisdom on that page.
