Loss of diversity is bad. Everything else is all right, as long as in the long term there is no loss of diversity.

The trouble is, that at the current state of science and technology we can not engineer and control ecosystems. We can not even model ecosystems. As a result we are breaking things and we even have no idea how badly we are breaking things when we are extracting resources. Like when we are turning diverse ecologies into monocultures, when forests are being turned into these 'beautiful' fields of golden wheat.

It does NOT have to be that way. There is no natural law that says that it is necessary to destroy diversity if one wants to grow food or extract resources. It is just that our technology is very primitive and that's the only way we've been able to do it so far. With right technology one can have it both ways. But we don't have it. Not yet.

And meanwhile, well. Conservation, common sense and minimizing our damage to the ecology is probably a best that we can do...
