Dating back to 1950, it was believed that economic growth was inextricably linked to the nation's carbon dioxide emissions. The more the U.S. produced, manufactured, provided and even polluted the more wealth there was to go around. Then courses were altered. In the last few years, carbon emissions stayed flat and are now predicted to decline over the next decade as new environmental regulations take hold and more conscientious minds begin to consider the effects on the planet. At the same time, however, the nation's gross domestic product has continued to rise. Breaking up this union gives hope for simultaneous prosperity and environmental stewardship in the face of climate change.
