Some of the inventions that make our lives easier are also causing pollution. Pollution is the release of harmful substances into the environment. One form of pollution is acid rain. Acid rain can damage plants, animals, soil, water, building materials, and people. Scientists have discovered that burning fossil fuels creates acid rain through air pollution.
People burn fossil fuels such as coal and oil to make electricity.
Electricity heats and lights buildings and runs appliances such as televisions and video recorders. Fossil fuels power our cars, buses, and airplanes. The air pollution created when these fuels burn does not stay in the air forever. It can return to the earth as acid rain. And when it does, it may weaken the plant and animal life it contacts.
