He has authored 43 books, encourages green living with his Nature Challenge, and founded the David Suzuki Foundation, which helps promote sustainable fishing and renewable energy. Today Suzuki, in his early seventies, lives in Vancouver and continues to fight greenwashing politicians and recently sat down with TreeHugger Radio.

Two-time Pulitzer prize winner Edward Osborne (E.O.) Wilson, an American biologist, conservationist, author, and the "father of biophilia", the idea that humans have an innate love for nature, has been an active environmentalist since the 1960s. E.O. Wilson developed the idea for the Encyclopedia of Life in 2003 as a way of chronicling all of the world's species, Wikipedia-style. TreeHugger got a chance to speak with him at the Goldman Environmental Prize ceremony at the Smithsonian in Washington, D.C. this year. At the age of 80, Wilson is Pellegrino University Research Professor in Entomology for the Department of Organismic and Evolutionary Biology at Harvard University. Wilson is also a Fellow of the Committee for Skeptical Inquiry and is a Humanist Laureate of the International Academy of Humanism.

Credit David Friedlander Stewart Brand, author, editor, and creator of the "Whole Earth Catalog", published between 1968-1972, as well as the forthcoming, "Whole Earth Discipline" writes, "We are as gods and might as well get good at it." This statement resonated in his recent presentation at TED@State, a one-day mini-conference sponsored by the US State Department, and organized by TED. Brand outlined his plan on how to save the world from a global environmental and societal meltdown. When he's not speaking at TED, Brand can be found on his tugboat in Sausalito, California where he lives with his wife. According to The New York Times, out of his deceased Woodstock-Era pals, he wishes he could see activist Abbie Hoffman again.

Earth Day is a major holiday at TreeHugger and it won our Best of Green award for Best Green Event this year. Today, Earth Day is celebrated in more than 180 countries and Hayes continues to chair the board at Earth Day Network.

American environmentalist Lester R. Brown founded the Worldwatch Institute in 1974 and for 26 years held the position of president. Now Brown is the founder and president of Earth Policy Institute, an organization "dedicated to building a sustainable future," and has been described by The Washington Post as "one of the world's most influential thinkers." His most recent book Plan B 3.0: Mobilizing to Save Civilization, addresses his vision for an environmentally sustainable economy. Today Brown is in his mid-seventies, resides in Washington, D.C., and when not penning a book (he has authored/co-authored over 50) he can be found writing for TreeHugger on topics from The Oil Intensity Of Food to A Warming World Means More Destructive Storms.
