n They took all the trees, and put em in a tree museum
And they charged the people a dollar and a half to see them
***
Don't it always seem to go
That you don't know what you got 'til it's gone
They paved paradise, and put up a parking lot
Big Yellow Taxi by Joni Mitchelln
This book is the second in a series by this author that began with Guns, Germs and Steel: The Fates of Human Societies, which I read and reviewed. In that book the author deals with the question of why some societies/people are more successful than others. This book serves as a supplement to that book in that it examines the same question, but here his primary focus is on the environmental factors and the ways that societies respond to them. He gives short histories of various civilizations, both ancient and modern, and the environmental problems that they created or faced. These histories describe civilizations that collapsed or are collapsing and contrasts them with civilizations that succeeded in managing their environment.
There are several environmental factors that affected these civilizations. The list contains things like climate change, soil erosion, water management, overpopulation, introduced foreign pests, toxic wastes, and many others. His main focus is on deforestation, which in many cases contributed to some of the other problems.
Some of the environmental problems can be linked to something the author refers to as the “tragedy of commons.” This is when a community all harvests a resource from a common source, for instance, a forest, a communal pasture for grazing, or the fish in the ocean or a river. Because it is a shared resource, but lacks effective regulation there is no compulsion for an individual to limit their harvest. This has led to many resources being over-harvested and destroyed.
The author does point out some positive trends. He uses a Top-Down and Bottom-Up framework to discuss some success stories. An example of a successful country’s management of their environment is Japan. They realized early that due to their isolation from other countries the people depended on their own natural resources and took steps to prevent things like over-harvesting. In China the government has instituted the one child rule, and also implemented some positive programs to save their environment. These were examples of Top-Down approach in that it was the leaders of the country that implemented the conservation measures. In describing the situation on the South Pacific island of Tikopia he describes a Bottom-Up approach. This civilization had no strong central government so the people themselves implemented measures to save their environment and control population. They made a decision to kill every pig on the island because they were destroying gardens even though they were a source of protein.
He describes the per-capita impact of humans. This is the average resource consumption and waste production of one person. This impact is much higher in First World countries than in Third World countries. However, with the globalization of communication people in Third World countries want the same standard of living as those they see living in First World countries. This impact is also increasing due to increased immigration to First World countries and the subsequent assumption of their living standard. One observer is quoted as saying “The apocalypse here will not take the form of an earthquake or hurricane, but of a world buried in garbage.” (Page 351)
Just like maintaining the health of our bodies, preventing environmental messes is cheaper in the long run. The financial costs resulting from people getting sick from air pollution, the increase in prices due to the destruction of fish habitat, the time spent in traffic, the cleanup of toxic chemicals, and the lack of clean water can run into the billions. The horrific view is that if ancient civilizations collapsed due to environmental problems with their primitive tools and relatively small populations, what impact might we have with our heavy machinery and nuclear power.
This was a very educational read for me. In addition to learning a context in which to think about our environmental problems, I learned valuable lessons in the histories of some civilizations which I doubt I would have ever read. However, the book did become a slog at times. Many of the histories seemed to repeat things and it got a little wordy. The Norse settlement in Greenland lasted about 500 years and it seemed to take that long to read.
This is an important book. Unlike the Norse of Greenland, or the Polynesian natives on Easter Island, we cannot plea ignorance of our environmental problems. Unfortunately many people who make some of those decisions choose to ignore this problem. As the author points out a few times (and I paraphrase):
n The rich and powerful only earn the privilege of being the last ones to starve.n
