YOU FOLLOW: Tim Hurst (@ecopolitologist) for the stories missed by the mainstream media; urban farmer @majoracarter and journalist @michaelpollan for sharp insight on the politics of food; and @drgrist, Grist blogger David Roberts, for his posts on energy policy: “U.S. 2020 climate treaty proposal isn’t a delay—it’s a death sentence.”

Facebook
YOU LIKE: Extreme skier and activist Alison Gannett for her advice on growing winter vegetables and weatherproofing your home; the Nature Conservancy for inspiration and calls to action; and USFWS Climate Change, which is run by the U.S. Fish and Wildlife Service but takes gutsier stances than the EPA.

Apps
YOU USE: Green News as a bottomless ticker for environmental coverage from the major wire services; Fair Trade Finder to locate stores that stock responsibly produced products; Light Bulb Finder so you can pick the perfect Kelvin-scale light temperature for each room; and iScrap to find recyclers for those bulbs—or anything else—when they expire.

Web
YOU BROWSE: The obvious choices, like Grist, 350.org, and Andrew Revkin’s Dot Earth blog, but also Slate’s Green Lantern blog, where writer Brian Palmer gives the Myth Busters treatment to environmental questions; the website of the Guardian for its coverage of global warming rather than a debate over whether it exists; and the Real Climate blog for the pressing news that didn’t quite grab headlines.

YOU SCHMOOZE: By responding to @billmckibben’s tweets; organizing to feed the homeless at Care International’s charity clearinghouse, Care2.com; commenting on Facebook posts from the Natural Resources Defense Council’s comprehensive Switchboard blog; and creating petitions with the tools at protest site Environment.change.org.
