Eventually I finished this book, with more than a sigh of relief. I had the same trouble with his other book, Guns, Germs and Steel: the fate of human societies. I don't why his books are hard to read. They are not full of "isms", footnotes and long words that you need to look up on the internet.
It's rather that the book is like a sandwich, in that the filling is full of interesting stuff that you don't know, which keeps you reading, but the bread is rather stodgy and takes a lot of digesting. Which is odd, because the problem is that Diamond structures the book like those American school text books that my kids had in their international school. Each chapter started: now you are going to learn this, this and this, and it will help you understand that. In the middle there is a box making sure you know the main points of what you are learning. At the end there is a list of what you have learnt and what you will move on to. Although I didn't study from predigested pap like that, my kids did fine on it, so I don't knock it for school books. But it makes for rather repetitive reading as an adult, and if you disagree or want to ask questions, or discuss something, you can't. Come to think of it, aren't powerpoint slides, with all those bullet points stating the obvious, a continuation of this style? Let's all move over to the Edmund Tufte website, or wikipaedia.
Back to the book. Collapse: How societies choose to fail or survive, started as a course of lectures for undergraduates. However, they seem to be the sort of pure science undergrads who have never read any politics, economics, geography, ecology or anthropology. Maybe at that stage and given the normal state of knowledge in America about the non-American world, it is a valid assumption. Some American examples are given lest the message is missed at home.
Here is what you learn at the beginning of the book. Societies collapse because of five threats (memorise them for your multiple choice exam question): damage to the environment, climate change, hostile neighbours, loss of friendly trade partners and societal response to the problems the other factors cause. This even happens in Montana. Then follow some interesting examples: Easter Island, Pitcairn and Henderson Islands (in the Pacific), the Anasazi (in the US near the border with Mexico), the Mayas, the Vikings and Iceland, and Norse Greenland. The later examples have writing and can document their collapses. The reasons for the earlier collapses are developed by archeologists using a variety of methods and materials (carbon-dating, tree rings, ice cores, muck-middens etc).
At this stage, Diamond suggests that there are two possible societal responses which prove successful: top down, in large communities where rules are created by the appropriate power structure which is capable of enforcing them, or bottom up, in smaller communities, where the consequences of certain actions are obvious to the whole community, so can be communally agreed on and self-policed. Of course, these responses apply mainly to preventing environmental damage. But they are also applicable to the other threats.
He then goes on to discuss more modern societies and their problems: Rwanda (genocide caused by overpopulation), Dominican Republic and Haiti (different responses to similar problems on the same island), China (a mess of everything), and Australia (trapped by a "British" mentality, mining the wealth out of everything). The problem with a short chapter on such big problems, is that explanations become simplistic, but nevertheless they are new takes on old problems. I personally had never understood that overpopulation was a source of the genocide in Rwanda. And to suggest that war is an inevitable outcome of conflicts over food resources is heading down a slippery slope to justifying it.
Finally comes a section called Practical Lessons. This starts with a chapter on decision-making, taken from management literature, rather than political science, where you might expect it to come from, given the context and the title of the book. Here he lists five reasons why societal decisions may lead to collapse: failure to anticipate there being a problem (we didn't realise it mattered), failure to try to solve the problem (he calls it rational "bad" behaviour, on the assumption that people are rational, even in their bad behaviour), irrational behaviour (admitting that people are not rational, now), and lastly, that the solution to the problem may be beyond current capabilities (he suggests this where technology does not yet exist, or the solution is too costly). By far the most interesting (to me at least) is the part on "irrational behaviour", because it covers most of the real world cases: the clashes of values inherent in most political struggles; the influence of religion or conservatism, and the ability of society to change; the different access to resources that different political groups have, making the struggles unequal; the different perspectives of long and short term benefits; the motivation of capitalism; as well as psychological reasons: denial and group think.
But by now the book has forgotten about the other threats and concentrates on environmental damage. He then analyses the response of different industrial sectors (oil and gas companies, hard rock mining, logging, and fishing) to consumer pressure, showing how the big international oil companies are not the villains we thought they were. This title is awarded to third world oil companies (based on a sample of one). Mining companies become the new villains, as do rape and run logging companies in the third world. He identifies that consumer pressure (and employee pressure in the first world) is an effective change mechanism in demanding products produced in a sustainable way.
In the final chapter, he discusses life in Los Angeles, where he admits that transport is a major form of pollution as well as overpopulation. After debunking some excuses for doing nothing he exhorts consumers to get involved. But he doesn't really say how, except to buy properly labelled products, and not to blame big business which is just motivated by capitalism (which has made America great).
So in the end, the book isn't really credible as a wake up call to Americans (or others) to change their ways before imminent societal collapse, due to environmental damage. And it hardly confronts any of the other threats the author identifies as possible reasons for collapse.
Using the earlier parts of the book as examples, we could suggest
- pick the biggest, most urgent problem to solve (climate change perhaps, or keeping those trading partners with oil and gas friendly)
- confront psychological denial with regime change (or is this only recommended abroad?) using legitimate political means, not war
- learn to live with less (non-essential products, space, convenience) like the rest of the world already does
- (and even) too much food can be a killer as well as too little.
But somehow that's not what you expect in a textbook on the environment.
