Ed Begley Jr.
Environmental Activist
Emmy Award-Nominated Actor
Faced with growing environmental challenges, Ed Begley, Jr. exemplifies personal action by championing sustainability in Hollywood, serving on environmental boards, earning numerous accolades, and living in an eco-friendly home near Los Angeles.
As environmental issues become more pressing, there are two possible responses: forget it and hope that government and corporations will figure it out, or take action yourself.
In the “take action yourself” camp, a few individuals are leading the way. One such person in California is Ed Begley, Jr.
Turning up at Hollywood events on his bicycle, Ed has been considered an environmental leader in the Hollywood community for many years. He serves on the boards of The Coalition For Clean Air, and The Thoreau Institute.
His work in the environmental community has earned him a number of awards from some of the most prestigious environmental groups in the nation, including the California League of Conservation Voters, the Natural Resources Defense Council, The Coalition for Clean Air, Heal the Bay, Santa Monica Baykeeper, and the Cesar E. Chavez Foundation.
