37,10 €

Acid rain refers to precipitation containing higher than normal amounts of nitric and sulfuric acid and is a direct result of pollution that people release into the air. This fact-filled resource tells the story of how limits on pollution have made acid rain less of a problem in certain areas, including large parts of the United States. Sidebars and a pronunciation guide help young readers take away valuable, lasting information.
