Thinking it would be a good idea for me to review some of the books that I read, of which the non-fiction usually come under the category of science, anthropology or history, which I figure people here might be interested in.
Please feel free to contribute your own reviews or comments - reviews of non-fiction books of any genre are entirely welcome in this thread!
Collapse - Jared Diamond - (Anthropology, 2005)
His previous book that I read - Guns, Germs and Steel (1997) - is a classic in the world of anthropology. The central question driving his investigation was 'given that agriculture arose independently in both the middle east and the Americas, why was it Europe that invaded the Americas, and consequently dominated world politics, economic and culture for most of the time since, rather than the other way round?' - the (somewhat oversimplified, of course) conclusions being that the east-west axis of the Eurasian land mass allowed crops to spread in relatively similar conditions, rather than the north-south axis of the American land mass, leading to higher population density and more resistance to nastier bugs; horses being native to Eurasia rather than the Americas helped drive agriculture and industry, as well as adding military power; and the discovery of gunpowder, all factors that contributed to the decimation of thousands of Incan soldiers by only 168 Spanish men in 1532, and the eventual collapse of the Incan empire.
Collapse employs a similar range of scientific methods and similarly incredible rigour to analyse in-depth all of the factors present in those societies that have died out - for example, the natives of Easter Island, leaving their famous Moai statues, the Greenland Norse, and a few others - as well as in those societies that could have done, but didn't (e.g. Icelanders) and attempts to tease out the relative importance of each. Where we have written records, for example, with the Greenland Norse, we can see that they had contact with the local Inuit tribes, but had the misfortune of arriving at a time of near-optimal conditions for growing the crops they were used to growing at home and maintaining some of their prestige livestock (that were utterly unsuitable in the long-term to the local ecosystem) and assuming that these conditions would continue - but climates change naturally. Instead of making friends with the Inuit and copying their highly-advanced boat-building techniques and learning to fish and hunt whales, they stuck to their European and Christian values, and would even kill the Inuit on sight a lot of the time rather than trade with them. When temperatures dropped, and the soil, continually eroding due to deforestation, became less and less suitable for growing crops, they continued to choose to be wedded to their parent culture rather than adapt, and they all died out.
A similar story is told with the Easter Islanders, from whom there are no written records, but a variety of ingenious scientific and historical techniques can with remarkable accuracy lead to conclusions about the nature of their statues, and the original conditions when the island was first colonized. The recurring question that he asks, and is asked by students, is this: 'What must that man have been thinking, when he chopped down the very last tree on Easter Island?' There would have been such a man, and deforestation was the key factor in their demise. Wouldn't they have known the effects of their actions? Why did they do it, when they could maintain a perfectly-reasonable quality of life while maintaining or even regenerating the level of wood growing on the island?
He gives examples of cultures that have managed to live in somewhat balance with their surroundings, and how and why - the feudal Japanese, medieval Germans, and the particularly interesting case study of Haiti and the Dominican Republic, together making the island of Hispaniola, both appallingly-poor and with similar and highly intermingled histories and ecologies, but with very different results in today's reckoning, allowing the strength of various factors to be measured with reasonable degrees of certainty.
He also, heartbreakingly, looks at the eventual results of population pressure, a result of Malthus theory - the conflict between linearly-increasing production of food and exponential expansion of population. The example that sticks out is the Rwandan genocides, which while on the surface were a product of politicians setting family members against each other in an utterly inhumane attempt to consolidate power (another theme common to societies that kill themselves), was more driven by incredible levels of overpopulation and disastrous levels of agricultural efficiency. Tutsis and Hutus killed each other plenty, but both the genetic and cultural lines that divided them weren't actually that strong, and Tutsis killed Tutsis and Hutus killed Hutus aplenty, more than anything else because they didn't have enough food.
