I do, however, believe we should be working harder than we currently are to live in harmony with nature. We do have the power to do that, but instead we just sit around and say, "Something should be done," instead of actually doing something. Doing nothing at all can be just as bad as doing something wrong.And just because nature can take a punch doesn't give us the right to punch it. It's like saying we have the power to go out and punch some random person on the street, and they can take it, so we should do it. But we shouldn't really, just like we shouldn't be careless with nature. We should be going out of our way to live in harmony with nature, because nature is what allows us to live.
I agree with Bill on this one. The earth will substain itself and organisms will evolve and go extinct. It is how the earth goes. Humans will probably eventually die due to natural causes or unnatural ones by trying to manipulate universal processes or we will evolve. Hopefully our evolution would evolve for the better and not for the worse (greed would die out is what I mean). But I guess that is what makes us human is that we desire to make things better and end suffering but it is part of living.
