All things taken as equal, I consider myself a pretty good environmental citizen: I recycle, I take public transportation and my carbon score is pretty minimal. Now the fact that I don't own a car, heat and cool a palatial mansion or go on globe-trotting vacations probably helps and has more to do with my finances than my ethics, but that's a conversation for another time. Long before the Na'vi were making us feel guilty about the destruction of our 'hometree', there were oodles of movies out there carrying messages about respecting the earth. But I've never been big on reverence, so in honor of Earth Day I decided to be a little naughty and put together a list of five of the most unlovable environmentalists on the big screen.

Now before you think this is going to be all about environmental villains, let me clarify: I'm not just talking about the bad guys (although a couple of them made the short-list). Instead, I decided to go with a little bit of everything, and that's why your self-righteous do-gooders, your holier than thou types and even the downright silly made the cut (and remember what your mother told you about variety being the spice of life).

After the jump: my picks for five big-screen tree-huggers you love to hate...
