There are many pollution problems in Hong Kong.

Factories produce too much smoke. It causes air pollution. If we keep on causing air pollution, we won’t have any fresh air to breathe. And factories dump chemicals in rivers and the sea. It causes water pollution. If we keep on causing water pollution, we won’t have clean water to drink. Some people use too many plastic products. That is not good for the Earth. Roadworks and traffic make too much noise. If we keep on causing noise pollution, we won’t have a quiet place to live in.

We must protect the Earth!
