When it comes to nature, the preservationists are far from the on-the-ground reality; and yet they are not.
1. The on-the-ground reality is, Human Beings are stupid animals (I don't mean that in a bad way; all animals are smart in their own way, but I'm talking generally) and they simply do not have the intelligence, morals or ethics to self-regulate. Nor do they see what's going on around them (they lack situational awareness) in the big picture. They breed like rabbits and will continue to dominate their environment until such time as nature corrects them. Greed is good (Darwinian) and they pursue it. They think they are exempt from natural correction and so they keep fighting over that last morsel. Indeed, anyone who fails to compromise over that last morsel is considered unreasonable. Human Beings think the are flying instead of falling, and they think they can save themselves somehow if only they can have at that last morsel. Fact.
2. Preservationists mistakenly think Human Beings are smart, and capable of situational awareness, and morals, and ethics, and self-regulation, and looking around and seeing that the vast, overwhelming majority of the Earth is already their "multiple use" oyster; so they can't figure out why non-preservationists think the preservationist are out of touch with the on-the-ground reality. It is clear the on-the-ground reality is that non-preservationists have access to over 90% of the land mass, air and water, so the preservationists think the non-preservationists are the ones who are out of touch with the on-the-ground reality.
The preservationist is right and wrong. They are right about what is going on and the big picture, but they are wrong in thinking they can do anything about it. You can't fix stupid, no matter how many smart people there are. But as many great sport quotations provide, it's the trying that matters. Thus, the stupid people keep trying to get at that last morsel, and the smart people keeping trying to preserve it. And both sides, and the morsel, lose in then end. There is an even bigger picture though, and that is Christopher Stone's ontological problem: in the end we are but playthings made of straw.
