Canada is a resource rich nation, and its continued economic prosperity through a global recession has been due, to a large degree, to its ability to continue to sell commodities on the international market. It is widely seen as a more environmentally responsible and politically stable nation than most of the resource exporting developing countries. However, its image has been tarnished by its lack of environmental stewardship, resulting in certain limits on Canadian exports. The two greatest areas of negative impact are due to the seal hunt (which has spawned many international boycotts of Canadian goods -- pictures of Canadians beating baby harp seals to death is not a positive image) and the Athabasca oil sands which make Canadian oil some of the most environmentally harmful in the world and limit buying of Canadian oil by countries which have strong green guidelines. Environmental concerns have also delayed the Keystone pipeline.
