Edward Michael "Bear" Grylls

In August 2010 Grylls lead a team of five to take an ice-breaking rigid-inflatable boat (RIB) through 2,500 miles (4,000 km) of the ice strewn Northwest Passage. The expedition intended to raise awareness of the effects of global warming and to raise money for children's charity Global Angels.
