With the melting of the polar ice caps a lot more focus has been placed on the environment lately. Going green has been a popular topic, one that I have written about before as I compiled a list of green Web 2.0 sites. Well, I just found another site worth taking a look at called emPivot. emPivot, a Washinton, DC based startup, is like YouTube for "Green" videos as it offers a video sharing site specifically for "Green" media.
