paragraph

Answer 1

The United States and Canada cooperate on environmental protection through formal binational agreements and joint institutions. First, the 1991 Canada–United States Air Quality Agreement (with later updates) commits both countries to coordinated emissions reductions, shared air‑monitoring and modeling, and measures to cut sulfur and nitrogen oxides and ground‑level ozone—actions that reduce acid rain and cross‑border smog and help prevent future ecosystem and public‑health harms. Second, they work together under the Great Lakes Water Quality Agreement (revised in 2012) and through the International Joint Commission to clean up toxic hotspots, limit phosphorus and other nutrient runoff that causes harmful algal blooms, control invasive species, and jointly monitor and remediate water quality—steps that restore freshwater ecosystems now and reduce the risk of future contamination and loss. These cooperative efforts use shared science, funding, and coordinated policy to address transboundary problems neither country could solve alone.
