It is a good question, right now it is a problem, because we still need a lot of Nature that is around us to survive.
One problem is that if we head down a path, where we destroy all else, we have no option of changing our minds later if we do the wrong thing, or we find out that we do actually need other animals/plants.
The bigger issue might be that we don't need to keel everything in order to survive and grow. Right now we are doing things the completely wrong way. We clearly do not put a high enough value on our natural environment, and we have little studies of the long term effects of living in our modern world. A lot of problems like asthma may be exascerbated by the world we live in. We just don't know.
