We live in a world with very limited solutions to our sustainability problems.

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 gathersBelow the fold, I will offer some ideas about truly sustainable solutions.
