"Finding coal here, and little bit of oil there, and between that and the agricultural revolution, slowly our population crept up until we hit our fist one billion people," says Thom Hartmann, a best-selling author and progressive radio talk show host. "It didn't take us a hundred thousand years to go from one billion to two billion. Our second billion only took us a hundred and thirty years. We hit two billion people in 1930. Our third billion took only 30 years, 1960. It's amazing when you think about it. When John Kennedy was inaugurated, there were half as many people on the planet as there are today."

After 200 years of industrial revolution, the atmosphere has undergone a pronounced shift. "The earth has a natural greenhouse effect," explains Stephen H. Schneider, Professor and Senior Fellow at the Center for Environment Science and Policy of the Institute for International Studies. "In fact, we're about 60 degrees Fahrenheit warmer, thanks to those good guys, water vapor and carbon dioxide and methane – what we call 'greenhouse gases' – trapping heat. That’s the good part of the story. The problem is that humans are competing with nature in that when we use our tail pipes and our smoke stacks to put our waste into the atmosphere as if it's some kind of unpriced sewer, we're adding – to that amount of greenhouse gases that is natural – unnatural stuff, mostly more carbon dioxide, methane, chemicals that nobody's ever seen before, chlorofluorocarbons which also effect ozone. And when they build up, they trap extra heat."
