Why bother? Nothing's wrong

Why bother? There’s nothing wrong with the environment, right? The late Julian Simon has suggested that we have "the technology to feed, clothe, and supply energy to an ever-growing population for the next 7 billion years." No. Wrong. At the 2000 growth rate of 1.4 percent, that would be 6 billion x 1.0147,000,000,000 . I have yet to come across a calculator capable of calculating this, but it would mean that the mass of the population of the human race would far exceed the mass of the universe, which is estimated at 3 x 1055 g. At the 2000 growth rate, the number of people would exceed the number of atoms in the universe after 11,500 years. This is an example of R.A.S. (Rigorously Applied Stupidity). We shouldn’t be too hard on Dr. Simon. He worked for the Cato Institute, so it was his job to say silly things.

In fact, there are a number of serious threats to the environment, several of which have a very real potential to be a significant threat to the human race. The following list, while not totally exhaustive, does contain what I believe to the greatest threats to the human race.

Something totally off the radar of the media, mainstream or otherwise, is the threat of erosion and salinisation. While erosion is more of a concern in tropical and arid regions, and salinisation on prairies and in arid regions, people in temperate areas are not immune to its effects. Erosion in some regions it is so great that a tonne of produce comes at a cost of 20 tonnes of topsoil.2 In Canada, 38% of farmland in the prairies has areas significantly affected by salinisation.3 This is a relationship that cannot continue. The food we eat needs healthy topsoil to grow. Animals and animal products we rely on graze on land. The plants the animals graze on need topsoil. We cannot rely forever on artificial fertilisers, which compound the problem as well as introduce many more.

Deforestation is a problem that is often missed and its implications are almost always missed. The easiest way to create a desert is to cut down trees. Condensation drip from trees can account for as much as 80 to 86% of precipitation on upland slopes of coastlines. That’s precipitation that never registers on any rain gauges. Moving a few hundred kilometres in from the coast, 100% of the precipitation may be coming from trees. How do we know this? Most of the evaporation off of the ocean is H2O16. At the coast, 40% of the water in rain is H2O16. Trees, however, transpire H2O18. A few hundred km in from the coast, the rain is 100% H2O18. Cut the trees and you risk making a desert.

Additionally, there is the very general problem of pollution. According to the Environmental Law Centre at the University of Victoria “Public health experts estimate that air pollution is responsible for 16,000 premature deaths in this country each year; at this rate, forty Canadians die from air pollution-related causes each and every day.” And according to the World Health Organization, there are no safe levels for human exposure to ground-level ozone.4 Small particulate matter has been liked to many illnesses including ischemic stroke and other cardiovascular diseases5 and lung cancer.6 Auto exhaust has been linked to childhood cancers.7 This is to say nothing of dioxins and furans.

Acid rain is still with us and there are no places on the Earth left that are immune to rain acidic enough to kill trees. There are an estimated 142,000 lakes in Canada that have been damaged by acid rain.8

The vital Antarctic krill population has plummeted by 80% since the 1970s.9 Krill are not only a source of food for much of the Arctic and Antarctic life, they are also an important carbon sink.10 One result of carbon emissions is that the ocean is acidifying and much of the ocean life cannot tolerate this rapid change in pH, particularly life that incorporates calcium carbonate to make shells. We are well on our way towards making the oceans more acidic than they have been in 65 million years.11

Levels of carbon dioxide have spiked since 2002 above the alarming rates of increase in the late 1990s.12 Also disturbing have been predictions of an ice-free arctic ocean within the next 100 years13; melting of Greenland at rates 2 to 3 times the rate in 1996 that could see sea level rise by 7m14, the melting of Antarctica which could see ocean levels rise much more than that; and the news that peat bogs in Siberia are thawing and have the potential to release billions of tonnes of methane.15 (Methane is 20 times more powerful a greenhouse gas than carbon dioxide.)

Modern industrial agriculture depends on petroleum. Without cheap energy, farmers aren’t able to grow – a problem currently seen in the United States.16 The future of fossil fuels looks rather grim. It seems as though we are very close to a peak in the global production of oil. Discovery of oil reserves has already peaked with the last huge discoveries made in the 1960s.

We won’t be switching to natural gas. It has already peaked in North America and overseas transport is a risky proposition not only for the chance of accident but from the standard 2% or so that regularly leaks out. The global climate has enough methane in it as it is. Coal won’t do it. The U.S. coal reserves are estimated to last about 40 years if consumption rates are increased to just 8%.17 Nuclear won’t do it. At current rates of usage, there are 50 years left of cheap uranium reserves left in the world.18 Increase the rates of nuclear power generation and the depletion rate increases. Furthermore, uranium is mined using oil-powered machinery.

This is most important because, as Dr. Albert Bartlett says, “Modern agriculture is the use of land to convert petroleum into food.” The United States uses 10.25 quadrillion Btu of total energy in the food industry, 2.20 quadrillion Btu of which go into agricultural production.19 This is a practice that cannot and will not continue. It is the textbook meaning of unsustainable.

Also of concern is the rush to distribute as many genetically modified organisms into the environment as possible. Perhaps the most alarming of these has been pseudomonas syringae. It’s thought that pseudomonas syringae could play a role in up to 80% of the world’s rain formation. The genetically modified version is incapable of serving as a condensation point for rain droplets and is currently used to spray fruit crops to protect them from frost. So, we get to protect monoculture farmers and threaten life on the planet at the same time.

Ultimately, the bad news is that homo sapiens have reached a point where they are the single most influential species on the planet and that influence exerted is mostly negative. Don’t panic. This need not be the case. We have the practical knowledge to exert our influence an environment-enhancing way. Instead of wiping out species, we could be contributing to speciation. Instead of creating deserts, we could be reversing them and creating forests in their place. If you kick nature, nature kicks back harder. If you benefit nature with good design, you almost always get back more benefit than you designed for.

My only comment is that I am more interested in the practical solutions you guys a doing, and inspiring the rest of us, than I am in reading about the problems. They worry us all, but we have to tackle it at the grassroots level. I'd like to see your blog stay dedicated to putting out ideas and implementations along with the pics! So I would love to see you save the bandwith on this blog for that. Just my preference when visiting. There are just so many blogs exploring the problems :-/

When people start losing hope, it is amazing to see what teaching them skills like gardening and how to heat and cook with a woodstove does to their confidence, not in solving world problems, but in their ability to cope. That, to me, is the spirit of this blog.

Thanks for the comments, Rob. I was a bit worried about the timing of this piece - should I have waited for the other proactive parts, or posted it after I finished it?

Rest assured that there is more to come - both attempts to present permaculture theory in a solid way and give detailed practical information and case studies. Don't worry. This site is not going to become a catalogue of bad news (as the latest post shows, I hope). This is nearly the text behind part one of seminars I will be giving this summer.  

Editorial Notes: Douglas Barnes is a teacher, permaculture designer and consultant in Toronto. I kept a couple of comments from the original, because Rob expresses a valid concern. Douglas is part of the permaculture movement which is seeing Peak Oil as an opportunity to address these other ecological catastrophes. Check out Douglas and Scott A. Meister's permaculturetokyo.blogspot.org blog for lots of excellent sustainability oriented posts, including: -AF
