News release: “The U.S. Environmental Protection Agency is hosting a month-long online discussion to expand the conversation on acid rain. Acid rain is a serious environmental problem that affects large parts of the United States and is particularly damaging to lakes, streams, and forests and the plants and animals that live in these ecosystems. Sulfur dioxide (SO2) and nitrogen oxides (NOx), the pollutants that form acid rain, can cause serious respiratory illnesses and premature death.”
