Have you ever met an ex-environmentalist? I haven't. Once you are one, you stay one.
Since you found econesting, I'd venture to say that you probably are an environmentalist that knows a few treehuggers. Right?

Green technology and ecological news are constantly changing. For the uber-environmentalist on your list, give the latest and greatest environmental podcasts and videos.
