Two very different men are brought together by New Brunswick's decision to hand the management of millions of acres of Crown land to six multinationals. One man is an Acadian woodlot owner retired after nearly 40 years in a pulp mill; the other is a painter and winemaker with homes in France and New Brunswick. They travel to Finland to urge officials at one of the largest licence holders of New Brunswick Crown lands to practise responsible forestry, then go head-to-head with the provincial government to secure a new community-based forestry policy that is environmentally sustainable and produces more jobs than the highly mechanized techniques used today.

This video includes excellent scenery and computer-generated videos that provide nice visual aid. These visual aides and the facts given by the narrator deliver on the National Geographic credibility you have come to expect. It includes wildlife in the Denali area, including two moose battling for a mate, as well as a brown bear cub taking out a caribou. The wildlife portion takes up about half of the video, about 25 minutes or so. The second half of this DVD shows a group of eight individuals who are climbing Mt. Mckinley. This gives an additional viewpoint of the Denali area for those who seek challenging ventures. The cons about this video are that I would have liked to see a longer wildlife portion, and it is not a very long video altogether (50 minutes), so the $18 price tag seems a bit much. If you are interested in Alaska, the arctic, national parks, mountain trekking, and wildlife, this is a good movie for you.
