The important thing is to make further progress. Besides environmental costs, the economic and political costs of using fossil fuels is huge.

I had a discussion with a friend the other day, we could do a lot of damage to the middle east if we can get off oil as quickly as possible. We can also beat out China, who has a huge dependance on oil.

I'm not some drippy hippy saying we need to ban gasoline or something, but in the name of progress and our future it would be a very good idea to be wary of how much we dump into the atmosphere, and work on alternative energy.
