the interdependence of everything

Here's another example of why species preservation is so important. It's easy to mock the doomsaying cry of environmentalists calling for the salvation of some insect you've never even heard of before you discovered it was in danger of extinction. But, despite all the work of science, the interelationships among the millions of species on our planet is still an utter mystery. Who's to say that some endangered mite isn't the key link in the chain that supports our own survival--without our even knowing it? Who's to say what the precise fingers are that God uses to uphold the spinning circles of the world?
