After screwing in my first obnoxiously corkscrew-shaped, eco-friendly, fluorescent light bulb, I can't help but feel a little wronged by the well-intentioned, if blindly idealistic, green movement.

Let me clarify. I don't hate the planet, I don't drive a Hummer, and I love the whales. I am, however, a born skeptic and a wannabe history buff, so it's in my nature to approach saving the earth with caution as a watchword.

It seems to me that the only constant that's ever existed in the scientific world is that every couple of years everything we thought we knew gets turned on its head.

After all, wasn't it not too long ago that the now infamous DDT pesticide was touted as the savior of a malaria-ridden world? A few years and a lot few birds later we've come to believe we know better.

So global warming is happening; as an "enhanced greenhouse effect" it's tough to deny. It's natural to want to do something about it too; the problem is that it is easy to jump on board the bandwagon without really being informed.
