One of our staunchest allies, Tom Weis, ended his 2500 mile journey in the hybrid human-electric Rocket Trike this week–he crossed the country to take a message to US President Barack Obama and Chinese Premier Hu Jintao. He delivered a letter signed by 22 of the country's leading environmentalists demanding that they take bold action to return the planet's atmosphere to 350 ppm co2–we were so moved to see the roster of leaders joining the 350 call, from the Sierra Club's Executive Director Mike Brune to the Rev. Sally Bingham, founder of Interfaith Power and Light.
