Cross Border Environmental Issues
by Terry J. Keating
Canada and the United States share the longest international border in the world, across which flows people, goods, materials, wastes, and air and water pollution. Canada and the United States also share a long history of working together to address transboundary environmental challenges, dating back to the Boundary Waters Treaty of 1907. To coincide with A&WMA's 112th Annual Conference & Exhibition in Québec City later this month, this issue of EM includes a series of five articles that highlight some of the successes, challenges, and future directions of this
Canada–United States cooperation.
