Still holding out on this one? I don't think it has "everything to do" with humans, but "nothing to do with us" is as archaic a belief as the earth is flat. Basically that argument is that cars or factories don't produce things like smog, which anyone that lives in any major city knows is real.
If your argument is that a divine being or higher power has built in adequate compensation for humans or simply that its manifest destiny for humans to use the earth as it pleases, thats fine too, though it is a bit egocentric, similar to the belief that the earth is the center of the universe.
The truth is that humans in general have created a landscape that is making galactic changes less bareable. A person that stands outside in 1 spot for 365 days will experience changes resultant to natural changes of seasons. Sun, shade, night, rain, snow, etc. Same thing with the earth over the course of millenias. But if the person rips holes into their protective clothing knowing the various changes the spot he is standing on experiences, he cannot blame the spot for changing on him and claim that his ripping holes in his garmets had nothing to due with his sunburn or frostbite.
Now, its fine to say, "the rewards outweighed the risks" or "God destined human progress and that is what we did", but its laughable to say that there were absolutely zero result to any action humans have taken.
