With environmentalism being so hip and fashionable these days -- particularly on the corporate level -- every day kind of feels like Earth Day. Every other ad I see on TV is from some polluter-cum-born-again-environmentalist company touting its commitment to our planet. Every other news story concerns a company or municipality taking new measures to reduce its impact on Ma Nature. Everywhere I turn, I'm being force-fed tips on how to "green" this and how to "green" that. The message, and more specifically the word "green" itself, have become so saturated that they're practically meaningless.
