Bill McKibben is one of the world’s leading environmentalists and writers:

In 2009, he led the organization of 350.org, which organized what Foreign Policy magazine called “the largest ever global coordinated rally of any kind,” with 5,200 simultaneous demonstrations in 181 countries. The magazine named him to its inaugural list of the 100 most important global thinkers, and MSN named him one of the dozen most influential men of 2009.
