Some required reading in observance of the “green holy day,” aka Earth Day (April 22), from Steven Landsburg’s book “Armchair Economist,” in the chapter titled “Why I Am Not an Environmentalist: The Science of Economics versus the Religion of Ecology“:
The hallmark of science is a commitment to follow arguments to their logical conclusions; the hallmark of certain kinds of religion is a slick appeal to logic followed by a hasty retreat if it points in an unexpected direction. Environmentalists can quote reams of statistics on the importance of trees and then jump to the conclusion that recycling paper is a good idea. But the opposite conclusion makes equal sense. I am sure that if we found a way to recycle beef, the population of cattle would go down, not up. If you want ranchers to keep a lot of cattle, you should eat a lot of beef. Recycling paper eliminates the incentive for paper companies to plant more trees and can cause forests to shrink. If you want large forests, your best strategy might be to use paper as wastefully as possible [MP: e.g. print as many emails as possible]— or lobby for subsidies to the logging industry. Mention this to an environmentalist. My own experience is that you will be met with some equivalent of the beatific smile of a door-to-door evangelist stumped by an unexpected challenge, but secure in his grasp of Divine Revelation.
This suggests that environmentalists — at least the ones I have met — have no real interest in maintaining the tree population. If they did, they would seriously inquire into the long-term effects of recycling. I suspect that they don’t want to do that because their real concern is with the ritual of recycling itself, not with its consequences. The underlying need to sacrifice, and to compel others to sacrifice, is a fundamentally religious impulse.
Suggesting an actual solution to an environmental problem is a poor way to impress an environmentalist, unless your solution happens to feed his sense of moral superiority. Subsidies to logging, the use of pesticides, planned extinctions, and exporting pollution to Mexico are outside the catechism; subsidies to mass transportation, the use of catalytic converters, planned fuel economy standards, and exporting industry from the Pacific Northwest are part of the infallible doctrine. Solutions seem to fall into one category or the other not according to their actual utility but according to their consistency with environmentalist dogma.
