One can fully own a manufactured thing—a toaster, say, or a pair of shoes. But in what reasonable sense can one fully "own" and have "rights" to do whatever we want to land, water, air, and forests, which are among the most valuable assets in humanity's basic endowments? To say, in the march of eons, that we own these things into which we suddenly, fleetingly appear and from which we will soon vanish is like a newborn laying claim to the maternity ward, or a candle asserting ownership of the cake; we might as well declare that, having been handed a ticket to ride, we've bought the train. Let's be serious.
