The Ecological Society of America has just published another edition of its Issues in Ecology series.

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.

Issues in Ecology #14 is available for free as a pdf on ESA's website:
