We have in the last forty/fifty/sixty years done many things to improve greenhouse gas emissions. I clearly remember teachers telling us as students in different school classes in the sixties that our planet was getting warmer. However, that and the improvements I have seen probably are not related; such as better economy in cars. Most cars in the sixties were gas guzzlerling 400 horse power sleds. Now only small percentages are (toyotas as opposed to Dodge Hemis). The consumer changed that, and gas prices, not the government. That is unless of course we consider our governments lack of inovation and intervention which contributed to the current state of gas supplies and its cost at the pumps policy change. In regard to all the rest of eternity it will probably be "us" that makes or forces change that rectifies the serious prblems related to carbon emissions. That and taking away some of John Travolta's jet planes.
