Old power plants release nitrogen oxides in large quantities, which contribute to the formation of ozone – a primary component of smog. According to the EPA, exposure to smog decreases lung function, aggravates pre-existing lung disease, increases hospital emergency visits and admissions, and can even lead to death.

Microscopic soot from power plants makes the problem even worse. Every year, thousands of people die because of the strain this air pollution puts on their bodies.

Toxic chemicals from old power plants leach into the soil and into the food chain. Mercury contaminates the fish we eat, risking brain damage, birth defects or retarded growth in children.
