A good idea if only because the natural world contains technology far beyond what humans are capable of engineering today. I use the word technology loosely here. Plants and animals are self-sustaining, self-replicating, intelligent, et cetera. We depend on this natural technology to survive.
However, it's a tough political sell for many people (and many powerful people). The more of us who put up money, the closer to the goal we are.
Charities such as the Nature Conservancy finance nature preserves... I'm curious about other organizations and philanthropists who do too.
