Air pollution is changing our environment and undermining many benefits we rely on from wild lands, threatening water purity, food production, and climate stability, according to a team of scientists writing in the 14th edition of the Ecological Society of America's Issues in Ecology. In "Setting Limits: Using Air Pollution Thresholds to Protect and Restore U.S. Ecosystems," lead author Mark Fenn (USDA Forest Service) and nine colleagues review current pollution evaluation criteria. The authors propose science-based strategies to set new limits and put the brakes on acid rain, algal blooms, and accumulation of toxic mercury in plants and animals.
