Ray Mears' epic adventure into Canada's unforgiving, yet stunning wilderness begins in the vast northern Boreal Forest, at the heart of Canada. Like the Amazon, the Boreal Forest is of critical importance to all living things. Its trees and peatlands comprise one of the world's largest carbon reservoirs. Its wetlands filter millions of gallons of water each day. This vast and intact forest ecosystem is home to moose and beaver, birch and spruce, insects and people.
