22. Ironman (2013)

He's been called a geo-vigilante, an eco-terrorist, or alternatively a visionary who simply wants to save the world. For years, American businessman Russ George has nurtured a controversial idea: to fix global warming by seeding the ocean with iron. Thumbing his nose at U.N. conventions and possibly Canadian law, George teamed up with a Haida village on B.C.'s West Coast and carried out the biggest iron fertilization project to date.
