not modern man at least...but historically, humans have been in a much smaller part of an ecosystem and thus the effects of humans had a much smaller effect on the ecosystem as a whole...humans had small plots of land to cultivate food, a few livestock...people were self sufficient

look at what extensive agriculture and the manipulation of species has done to the earth (for the sake of human survival?) we are the top of the food chain, just because we are humans, this does not mean we are exempt from the laws of nature...what happens when the predator becomes too many? there arent enough resources to sustain that "predator"... what happens when a group doesnt have enough resources?

soil continually loses its nutrients...the air, earth, and water are contaminated with countless pesticides and chemicals...species are dying left and right....we as humans have overstepped our bounds and our role as caretakers of the planet...we shouldnt be raping the land by continually growing agriculture (but what choice do we have? we have to take care of the human overpopulation?)
