You're right in a sense. I am trying to be controversial here: I remember high school courses teaches us that nature, through natural selection, influenced mankind. Until man empowered enough intelligence and influence back its environment, through Agriculture first, shaping the lands, steering water streams and so on. Then through industrial revolution. Generating green house gas emissions. I am not sure which one of a bushman or a agriculture lead to the best ecologic behavior then. :-/
