The Forest Watchers tells us some remarkable things about one of our great natural resources. For example, although nearly one half of Canada is forest, by the end of the century the supply might fall short of the demand. The film explains why, and describes what is being done to stem the disaster. Methods range from trekking through the forest on foot to the use of highly sophisticated technology. The data compiled are far from reassuring. Is there time to salvage this fast-dying resource?
