“Actor Mark Ruffalo, who lives in a rural New York town on the Delaware River with his family, is not one of those celebrities who parachutes into a random political cause and starts ignorantly pontificating about solutions. He has been actively involved with efforts to keep potentially disastrous hydrofracking practices out of New York State for three years, and he knows his stuff. He’s even co-founded his own initiative on water quality, Water Defense.

Now Ruffalo has banded together with some other famous friends, including Ethan Hawke and Zoe Saldana, to make a new video, “I Love My New York Water,” that he hopes will encourage people to get involved in the battle to keep New York’s water safe from the effects of hydrofracking. Fracking, in case you don’t know, is a controversial natural gas extraction process that has the potential to cause severe environmental damage (remember the flaming faucets in Gasland?). “It is a new technology, ” Ruffalo told me. “The industry is using us as guinea pigs. The more we learn about it, the uglier it looks.”
