Collapse: How Societies Choose to Fail or Survive

Jared Diamond

Book Review

This book was very different from what I expected. I anticipated an account of the environmental mismanagement that caused the collapse of prehistoric civilizations such as Easter Island. Collapse is actually a detailed historical analysis of a wide spectrum of both failed and successful societies. In addition to Easter Island, Diamond also covers the vanished Anazazi civilization in New Mexico, the Mayan civilization, the Viking settlements of Iceland (which persists to the present day), Greenland and Vineland (present day Newfoundland and New Brunswick), pre-1853 Japan, the New Guinea highlands and modern day Rwanda and Australia (the modern society he describes at highest risk for collapse).

Diamond’s thesis is that the ability of any society to meet the survival needs of its members depends on certain basic preconditions. He maintains historical forest management is the most critical – deforestation features in every historical collapse he mentions. Forests are not only essential to provide fuel for cooking, heating and refining metal, but loss of forest cover leads to soil erosion and destruction of topsoil, as well as decreased rainfall and fresh water shortages.

In some societies Diamond analyzes, collapse was the direct result of environmental mismanagement. In others, the odds of survival were extremely low to begin with, due to low rainfall, a cold or windy latitude or poor soils. In many cases, a political factor such as war, lack of external supports (eg trade), overpopulation and/or a greedy ruling elite diverting resources to luxuries were important contributing factors.

The section I found most interesting concerns the New Guinea highlanders, who (prior to the arrival of Europeans) maintained an environmentally sustainable civilization via bottom up direct democracy for over 46,000 years.
