After winning the snowboard cross gold four years in a row at the Winter X Games, Holland is heading to Vancouver hungry for another Olympic medal. Off the hill, Holland is involved with Protect Our Winters, a nonprofit formed by professional snowboarder Jeremy Jones. The group wants to unite the winter sports community to reverse global warming.
