A few years ago, I had an ah-ha moment when it comes to what we as humans would need to do to live in a sustainable manner. It is very easy. All we have to do is leave our homes, take off all of our clothes, and learn to live on the raw food we are able to gather with our own hands. We have a built-in transportation system, so that is not a problem.
Some animals are eusocial, that is, organized in away that allows for cooperative brood care and other joint tasks. If we follow that approach, we would get our extended families to join us living in nature, au naturel. We could then co-operate on tasks such as child rearing and gathering food.
Nature’s Provision for Order
Nature is organized in a number of ways that make certain that there will be modest change over time to adapt to new conditions, but that no one species will dominate. These are a few of the basic parts of the system: Continue reading

Jared Diamond calls it “the worst mistake in the history of the human race.”(1) Bill Mollison says that it can “destroy whole landscapes.”(2) Are they describing nuclear energy? Suburbia? Coal mining? No. They are talking about agriculture. The problem is not simply that farming in its current industrial manifestation is destroying topsoil and biodiversity. Agriculture in any form is inherently unsustainable. At its doorstep can also be laid the basis of our culture’s split between humans and nature, much disease and poor health, and the origins of dominator hierarchies and the police state. Those are big claims, so let’s explore them. Continue reading
We live in a world with very limited solutions to our sustainability problems. I often hear the view, “If we would just get off fossil fuels, then our society would be sustainable.” Or, “If the price of oil would just go high enough, then renewables would become economic, and our economy would be sustainable.”
Unfortunately, our problems with sustainability began a long time before fossil fuels came around, and the views above represent an incomplete understanding of our predicament. When fossil fuels became available, they were a solution to other sustainability problems–rapid deforestation and difficulty feeding the population at that time. Getting rid of fossil fuels would likely lead to very rapid deforestation and many people dying of lack of water or food. If getting rid of fossil fuels is a solution to our predicament, it is one with very bad side effects.
A couple of different events this week reminded me about how deeply embedded our sustainability problems are. For one, I had the opportunity to read a draft of a soon-to-be published paper by James H. Brown and a group of others from the University of New Mexico and the Sante Fe Institute called, “The Macroecology of Sustainability.” This paper points out that sustainability science has developed largely independently from and with little reference to key ecological principles that govern life on earth. Instead, sustainability science is often more of a social science, looking at slightly greener approaches which are almost as unsustainable as the approaches they replace.
A second thing that reminded me of our long-term problems with sustainability was a pair of articles in this week’s issue of Science. There is a research article called, The Aftermath of Megafaunal Extinction: Ecosystem Transformation in Pleistocene Australia by S. Rule et al, and an accompanying perspective article called The Hunters Did It by M. McGlone. The perspective article explains that there had been a controversy as to why marked changes in habitat took place shortly after humans settled Australia. Some thought that the loss of forest and animal extinctions were the result of climate change. New research shows that the changes almost certainly came from hunting and the use of fire by humans. This is further evidence that humans did not live sustainably, even when they were still hunters and gatherers. (See my earlier posts, European Debt Crisis and Sustainability and Human population overshoot–what went wrong?)
Below the fold, I will offer some ideas about truly sustainable solutions. Continue reading
What would humans have to do to really live sustainability with the world’s ecosystems?
I got a shock when I read about the pattern of species extinctions which is taking place that form a part of what is called the “Sixth Mass Extinction.” It turns out that man’s adverse influence on ecosystems didn’t start a few hundred years ago, when we started using fossil fuels. Instead it started way back, when man was still a hunter-gatherer, and there were fewer than 100,000 people on earth.
According to Niles Eldridge, in describing the Sixth Extinction:
- Phase One began when the first modern humans began to disperse to different parts of the world about 100,000 years ago.
- Phase Two began about 10,000 years ago when humans turned to agriculture.
In this post, I’ll explain a little more about the Sixth Mass Extinction, and how fossil fuel use has contributed to it in recent years.
I’ll also talk about a new bottleneck that humans seem to be reaching related to oil limits and financial crises that grow out of these oil limits, with the current example being the European Debt Crisis. Depending how this and other debt crises work out, it seems possible that human population will decline. If this should happen, it could lead to a reduced problem with species extinction.
But the whole situation illustrates just how difficult attaining sustainability with world ecosystems is likely to be. Humans by their nature seem not to mesh well with world ecosystems. Unless humans become completely extinct, it seems likely that humans will always have difficulty living in a truly sustainable way.
