What are three seasons diamond discusses as to why we cannot trust technology to prevent the collapse?

One of the disturbing facts of history is that so many civilizations collapse. Few people, however, least of all our politicians, realize that a primary cause of the collapse of those societies has been the destruction of the environmental resources on which they depended. Fewer still appreciate that many of those civilizations share a sharp curve of decline. Indeed, a society's demise may begin only a decade or two after it reaches its peak population, wealth, and power.

Another popular misconception is that we can trust in technology to solve our problems. Whatever environmental problem you name, you can also name some hoped-for technological solution under discussion. Some of us have faith that we shall solve our dependence on fossil fuels by developing new technologies for hydrogen engines, wind energy, or solar energy. Some of us have faith that we shall solve our food problems with new or soon-to-be-developed genetically modified crops. Some of us have faith that new technologies will succeed in cleaning up the toxic materials in our air, water, soil, and foods without the horrendous cleanup expenses that we now incur.

The final misconception holds that environmentalists are fear-mongering, overreacting extremists whose predictions of impending disaster have been proved wrong before and will be proved wrong again. Behold, say the optimists: water still flows from our faucets, the grass is still green, and the supermarkets are full of food. We are more prosperous than ever before, and that's the final proof that our system works.
