In the 60's and 70's, Julian Simon went head-to-head against the doomsday preachers of environmentalism. In this book he examines why there are so many biologists who are environmental alarmists, and why the alarmist point of view is so dominant in the media and public discourse--especially when so much evidence exists that this point of view is wrong!! Simon then presents a better way of approaching these important issues--including a scientific (as opposed to a political-psychological) approach to understanding the true state of our world. A key contribution Simon is able to make as an economist is to point out and explain important fallacious assumptions of the environmental doomsters: 1) zero-sum mentality, 2)finiteness as a starting point of reasoning, 3) and the lack of an understanding of the processes of wealth creation and efficient resource utilization.
