No enterprise on earth makes American environmental activists more hysterical than Canada's oil sands. The relentless demonizing has had real effects: witness President Obama's refusal to say "Yes" to the Keystone XL pipeline and the thousands of shovel-ready jobs that would come with it. But ordinary people who prefer Canadian oil to OPEC oil also have a voice. They can make themselves heard, and cause the best laid plans of eco-activists to backfire. The saga of the Chiquita boycott proves this.
