People also throw garbage into rivers and lakes. This pollution harms fish and other marine life. Many sea animals, including whales and dolphins, have been found sick or dead because of pollution. Unsafe water also makes millions of people sick every year. Governments are working to clean up polluted rivers and lakes.

Noise pollution comes from traffic, factories, construction sites and loud music. It can cause hearing loss and stress in humans. It also harms animals, especially those that use sound to communicate, such as whales and dolphins. Light pollution comes from street lights, billboards and building lights. It makes it difficult to see the stars at night. It also affects animals that are active at night, like birds and insects. Light pollution can cause birds to get lost during migration. Many cities are now trying to reduce light pollution by using fewer lights at night and directing lights downward. Governments are also setting noise limits to reduce noise pollution. We should all be more aware of these hidden forms of pollution. ( )11. Where does noise pollution come from? A. Traffic, factories and construction sites. B. Street lights and billboards. C.
