Garnering considerable buzz in the world of politics as of late, the micro-blogging tool twitter <http://mashable.com/2009/03/16/twittergrowth-rate-versus-facebook/> is growing at an astonishing 1,382 percent—adding 7 million new accounts in February alone—and showing little sign of slowing down. Although politicians themselves may be relative newcomers in the world of communicating in 140-character or less, those who write about and study politics aren’t. And that goes for those who favor environmental politics, too. The following is a list of eco-political twitters:
