Human Impacts
Humans are consuming more and more of the natural resources provided by the biosphere. As both population growth and per capita consumption increase, this stress can only be expected to continue its unchecked growth into the future. Different populations around the world are dealing with these environmental pressures in varying ways from implementing so-called green policies to doing nothing at all. The future of the biosphere will be determined by the decisions of today's policy makers.
