The importance of being earnest
A certain blogger recently recommended buying ladybugs to release in your yard for pest control. I don't want to single out this endearing and admirable person, but this is a perfect example of making things worse by trying to make them better. A little bit of research, not to say common sense, would reveal that kidnapping bugs en masse and selling them to gardeners is not a good idea.
This is what is so dangerous about the current "green" climate in America: it can easily do more harm than good, as with ethanol, which, if you weren't paying attention, is currently responsible for starving the developing world, consuming more energy than it produces, and the rising prices you're paying for gas and food.
So if you're going to do something -- especially if you're going to publicly advocate doing something -- to make the world better, make sure it will actually make the world better.
[Brendan I. Koerner's Green Lantern column at Slate is an interesting attempt to do this.]
