"Why I Am Not An Environmentalist"

But in the 25 years since the first Earth Day, a new and ugly element has emerged in the form of one side's conviction that its preferences are Right and the other side's are Wrong. The science of economics shuns such moral posturing; the religion of environmentalism embraces it.

Economics forces us to confront a fundamental symmetry. The conflict arises because each side wants to allocate the same resource in a different way. Jack wants his woodland at the expense of Jill's parking space and Jill wants her parking space at the expense of Jack's woodland. That formulation is morally neutral and should serve as a warning against assigning exalted moral status to either Jack or Jill.

The symmetries run deeper. Environmentalists claim that wilderness should take precedence over parking because a decision to pave is "irrevocable." Of course they are right, but they overlook the fact that a decision not to pave is equally irrevocable. Unless we pave today, my opportunity to park tomorrow is lost as irretrievably as tomorrow itself will be lost. The ability to park in a more distant future might be a quite inadequate substitute for that lost opportunity.

A variation on the environmentalist theme is that we owe the wilderness option not to ourselves but to future generations. But do we have any reason to think that future generations will prefer inheriting the wilderness to inheriting the profits from the parking lot? That is one of the first questions that would be raised in any honest scientific inquiry.

Another variation is that the parking lot's developer is motivated by profits, not preferences. To this there are two replies. First, the developer's profits are generated by his customers' preferences; the ultimate conflict is not with the developer but with those who prefer to park. Second, the implication of the argument is that a preference for a profit is somehow morally inferior to a preference for a wilderness, which is just the sort of posturing that the argument was designed to avoid.

It seems to me that the "irrevocability" argument, the "future generations" argument, and the "preferences not profits" argument all rely on false distinctions that wither before honest scrutiny. Why, then, do some environmentalists repeat these arguments? Perhaps honest scrutiny is simply not a part of their agenda. In many cases, they begin with the postulate that they hold the moral high ground, and conclude that they are thereby licensed to disseminate intellectually dishonest propaganda as long as it serves the higher purpose of winning converts to the cause.
. . .
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
