This article examines the ecological and economic impacts of unchecked cross-border environmental transfers between the United States and Canada, including invasive species, air pollution, and agricultural runoff. It highlights the need for stronger cooperation and policy alignment to address these shared challenges.
Emily Waugh, a Toronto-based writer and former lecturer in landscape architecture at the Harvard University Graduate School of Design, explores the complex ecological and economic impacts of cross-border environmental issues between the United States and Canada.
Vladimir Menkov, a resident of B.C. ’s Okanagan Valley, initially believed his south-facing fence would shield his yard from tumbleweeds drifting up from Washington.
However, he soon realized that without regular maintenance, these invasive plants would stack up, creating a ramp that allowed new tumbleweeds to breach the barrier entirely. This observation led him to ponder the broader implications of such unchecked cross-border movement, including the potential consequences of transporting tumbleweeds in a truck across the border. Unlike migratory birds, which freely traverse the U.S.-Canada border without customs scrutiny, food items like leftover duck enchiladas face strict regulations.
Canadian border authorities prohibit the entry of restaurant leftovers containing poultry, whether by vehicle or mail. The ecological and economic toll of such incidental cross-border transfers is substantial. Tumbleweeds, for instance, are invasive Russian Thistles that arrived in North America in 1873 via contaminated flaxseed from Siberia. They have since spread across the western U.S. and into Canada, causing significant agricultural damage.
Invasive weeds, pests, and pollutants continue to cross the border, affecting everything from forest health to air quality. The emerald ash borer, which likely entered Canada from Detroit, has devastated millions of ash trees, including those used by Indigenous communities for traditional crafts.
Meanwhile, air pollution from the U.S. contributes to health issues in Canada, with fine particulate matter and ozone linked to thousands of premature deaths annually. The interconnectedness of environmental policies between the two countries is evident in shared challenges like invasive species and water pollution. The Great Lakes, for example, face threats from Asian carp and agricultural runoff, while transboundary air pollution exacerbates respiratory problems.
Historical agreements, such as the 1991 Canada-U.S. Air Quality Agreement and the Migratory Bird Treaty Act, demonstrate the need for cooperation in addressing these issues. However, ongoing conflicts and policy shifts highlight the fragility of these partnerships. As climate change intensifies, the urgency of collaborative environmental action becomes ever more apparent
