There are more humans right now than there ever was ever before. The biosphere that supports us is already being strained by all our activities. The simple fact is that humans by default do impact our environment very strongly and negatively, especially for all the other species that we share it with. And that is why we need to be careful about minimizing our impact, not eliminating it altogether.

>So no, I do not believe that "we do damage to nature", because besides it being a nonsense statement, even the kernel of truth in it is wrong-headed in my opinion.

It is the general consensus of the scientific community that we do. How is it a nonsense statement?
