Sulfur, an essential nutrient for plants, was as free as air back in the 1980s, drifting down onto farmers' fields from the polluted sky. The nutrient also caused acid rain, however, and it triggered chemistry that meant ...

Acid rain is rain or any other form of precipitation that is unusually acidic. It has harmful effects on plants, aquatic animals, and infrastructure. Acid rain is mostly caused by human emissions of sulfur and nitrogen compounds which react in the atmosphere to produce acids. In recent years, many governments have introduced laws to reduce these emissions.
