Jean-Jacques Rousseau in his early writing contended that man is essentially good, a "noble savage" when in the "state of nature" (the state of all the other animals, and the condition man was in before the creation of civilization and society), and that good people are made unhappy and corrupted by their experiences in society. He viewed society as "artificial" and "corrupt" and that the furthering of society results in the continuing unhappiness of man.
Put another way, in the beginning civilized humans were hunters and gatherers, when we started wearing clothes made out of cotton, using deodorant, living in houses and using toilet paper we became savages.
The only difference between civilized "savages" and 20th century man is we used our opposing dumb to conquer Mother Earth.
The indigenous populations knew Nature was not "wild' and hostile but was a benevolent friend. Then, by a twist of organized religious dogma, many began to think humans are the greatest and most important part of creation and they saw Nature as "fallen' and sinful. Since the end of the "dark age" man has attempted to divorce himself from Nature to the detriment of all creation.

The characterization of the indigenous populations as being just as wasteful as a modern corporation is a popular notion among progressives and evolutionary psychologists.
The American Indians, according to this theory, are responsible for driving the bison off cliffs, killing the woolly mammoth and a number of other Pleistocene megafauna.
Paul S. Martin, geosciences professor emeritus, began writing about Pleistocene extinctions and Clovis people's sole responsibility for the "blitzkrieg" in 1967. (The Clovis were "paleo-Indians" named after the archaeological site in New Mexico where a characteristic spear point was discovered.)
