Daryl Hannah, that is.

Sure, every celeb can give lip service to positive change, but Hannah actually spends most of her spare time walking the walk. The latest proof is her video blog, a series of five-minute films that offer snapshots of how people around the globe are helping each other, and the earth.

In the first spot, Hannah takes a lick off the gas cap of her 1983 biodiesel el Camino. The french-fry grease that powers it, she says, has a toxicity level “somewhere between table salt and maple syrup.” For another, she filmed her visit to Rwanda, where she encountered mountain gorillas — the country is home to the last 350 of the endangered creatures — and helped christen a village’s cisterns for World Water Day. A third video finds her profiling an organic vegan “junk food” joint. She plans to debut a new movie every Monday.

I know it’s not strictly food-related, but check it out.

Random fact: though we named the newest canine addition to our family O-Ren Ishii, Elle Driver was a close runner-up.

Via Grist, which I should really add to the blogroll…
