Tobacco producers claimed for decades that there was no data to back up the claim that smoking cigarettes was bad for one’s health, and they had so-called experts support their position. I think it’s now generally agreed that they were wrong.

The debate about whether or not pollution and other consequences of human activity are contributing to global warming has been going on for years and will probably continue long into the future. There is data out there to support both sides of the debate. In the end, at some point probably far down the road, it will become obvious which side was actually right, but for now it would appear that the real “craziness” would be to jump to the conclusion that we don’t need to worry about being green precisely because it is “a subject as critical as this”. The cost of taking the anti-green approach and then finding out at that point down the road they were wrong could be catastrophic.

And congrats to Tide for finding a way to encourage people to save money and possibly help the environment at the same time. How can that be a bad thing?
