Nội dung bài nghe

Pollution is a problem in many places. But air pollution affects our town the most. It causes many diseases. Every year, thousands of people die because of air pollution. If we don't do anything to improve it, we will need to stay indoor most days. Children won't be able to play outside. And exercising outdoors will make you sick. So what can we do to reduce air pollution? The power plants often cause lots of air pollution. Our government should use renewable energy like solar or wind instead of coal or oil. Each of us should save electricity because it takes lots of energy to make electricity. The town should make public transportation better so people will use it more. If we all walk, ride our bikes, or use public transportation, there will be less traffic and air pollution.
