(Smoke from fires in the United States can also move north into Canada.) At the same time, regulation and financial incentives through taxes and subsidized lending rates can help redirect private capital toward projects that generate substantial long-term social and environmental benefits. Because Canada does not bear all the costs caused by the smoke, it may have less incentive to spend heavily on prevention. Cooperation between the two countries—including sharing information, responsibilities and costs—could lead to stronger efforts to prevent and control future fires. The smoke from Canada makes the idea of a common home strikingly literal.
