The concept of sustainability consists of living in a way that one could essentially live in that way forever, without fear of running out of any resource. The rate that humanity is currently living at would take six or more Earths’ to support. We only have one. We, as Americans, need to curb our resource use and develop Earth smart technologies that would further raise the standard of living around the globe. America in particular need to focus on this, and make it a requirement for the health of our nation, because as the largest consumer society that is setting an example for both growing India and China, we, as a nation of consumers, would lead other nations down the same path, as producers of all the stuff we buy, and help guide the global economy to make sustainable choices.
