A strongly-argued critique of environmentalism from the right - the conservative's answer to Al Gore's Earth in the Balance.
Peter Huber demonstrates that the green movement is mostly brown. The greatest threat to the environment would be your standard issue environmentalist, what Huber calls soft greens. People who care about the environment, but who want to depend on markets instead of coercion he calls hard greens. This is a great book. There are some evolutionary asides that are a distraction, so ignore those.
