The science on this is very overwhelming, and I think anyone would be hard pressed not to agree that climate change is due at least in part to man. I do not agree with the doomsday scenarios that some are painting. I tend to think that these pictures are painted for political and economic gain, not for actual planetary improvement. That said, I applaud anything that gets us away from foreign oil and reduces smog, carcinogens, and pollutants. Thus, I favor alternative energy. The problem is implementing these programs without having the government foot the bill on stupid ideas like ethanol.
