There are different kinds of pollution: air pollution, water pollution, and noise pollution. Air pollution comes from factories, cars, and planes. They put smoke and harmful gases into the air. Water pollution is caused by factories putting waste into rivers and people throwing litter into them. This kills fish and makes the water unsafe to drink. Noise pollution comes from loud music, cars, and construction. It can make people feel stressed and uncomfortable. In one town, the river used to be very clean. People could see fish swimming in it. But now, the river is dirty. Factories put waste into it, and people throw rubbish into it. The bottom of the river is full of litter. There are no more fish for fishermen to catch. The townspeople are worried. They want to do something to save the river. They plan to write to the government and ask them to close down the factories. They also want to organize a clean-up day to remove the rubbish from the river. Everyone should play a part in protecting the environment. Small actions, like not throwing litter and saving water, can make a big difference. ( ) 1. What are the three kinds of pollution mentioned in the passage? A.
