The 15 Most Eco-Friendly Rockers

Founder of The Eagles Don Henley, Rolling Stone's 87th greatest singer of all-time, created the Walden Woods Project in 1990 to increase awareness of and prevent development on the land of author and notable naturalist Henry David Thoreau. In 1993, Henley released Common Thread: The Songs of the Eagles, with proceeds going to the Walden Woods Project; five years later he assisted in the development of the Thoreau Institute to extend teachings of the intersection between philosophy and the environment. Henley's Caddo Lake Institute works simultaneously to fund ecological research, protecting the 26,000 acres of Texas wetland and the state's only natural lake, where Henley was raised.
