Why not? That’s like asking why buy gas at Texaco instead of BP; Because, Texaco hasn’t wrecked an ecosystem. Even if you chalk it up to innocent negligence, why wouldn’t you support the team that hasn’t screwed up? Fat Cow is ran on 100% wind energy and considering they don’t charge any more than anyone else, seems irresponsible to not use them. But, that’s just me. It’s the same reason I push the organic and value T’s in my shop. (by adding less markup) I believe that it’s necessary to infuse every action you take with as much social responsibility as possible. Where do you draw the line? Hybrid car? Giving to homeless people? That’s up to you . . .
