The second annual PlayGreen Festival runs Friday on the UC Berkeley campus. The festival grandly bills itself as “the eco-experiential lifestyle festival for people who want to play, work, and live a greener lifestyle”.

Visitors can see green cooking demonstrations, graze food from six local restaurants, visit booths from over 80 student and community groups, and attend workshops on a range of green pursuits. Among the cooking demonstrations is Nathan Downs showing how to make a Cambodian caramel dipping sauce. Downs is the executive chef to the Chancellor of UC Berkeley. I have to confess I didn’t realize that the chancellorship came with an executive chef.

I do, however, like the idea of “bring a tee, save a tree“. You can exchange any two old T-shirts for a new, organic cotton T-shirt. The old T-shirts will be recycled to create archival, 100% cotton paper.

The PlayGreen Festival runs from 10 a.m. to 4 p.m. in the Pauley Ball Room on the UC campus. Admission is free.
