Environmentalism, even at its most radical, is a human-centered project. It is about the kind of world we want for ourselves.
Living in harmony with abundant nature is not a sacrifice, but an expedience. Consider that we relatively privileged people already enjoy this relationship. We own houses with big backyards, ranches with hundreds of acres of land, weekend homes on lakes and mountains; we command beautiful views; we attend universities with manicured campuses; we take days off work to ski, golf, cycle; we partake in eco-tourism vacations or yoga retreats in secluded wilds; we breathe clean air and drink purified water; we buy organic produce.
But we ascribe to an economic system that deprives the rest of the world of the same.
