Photo: PBS Not that I'm f*cking (in love with) Matt Damon and would use even vaguely green news as an excuse to write about him -- what would give you that idea? -- but the Bourne star was spotted earlier this week taking a Tesla prototype for a spin.

The Robbinsville Professional Firefighters Local 3786 recently bought offsets for their two emergency vehicles through TerraPass. They're aware it's not a long-term solution but hope to "spark" awareness (heh heh!): "The goal is that …

I know no Grist reader will need this book (especially if you've got Grist's opus), but the ubiquitous bumblebee-colored series has now turned its all-dummifying eye to the environment.
