Joss Garman, 22 and just out of uni

Joss Garman, 22 and just out of university, has been a British environmental activist for eight years. Dubbed the "new Swampy", he has been arrested more than 20 times and helped set up Plane Stupid, a direct action group which in its short-haul life has infuriated airline companies and airports, disrupted the transport select committee and shut down easyJet's London offices. BAA tried to stop Garman and others organising the climate change camp at Heathrow last summer, but the camp went ahead and Garman demonstrated elsewhere. He was nominated by George Monbiot and Philip Pullman as one of the activists of the future. "He's now a campaigner at Greenpeace, though he's only about 12," Monbiot says.
