Smoke and waste chemicals are polluting the air and our environment. Smoke from cars, buses, trucks and motorbikes are very harmful. We are wasting too much power. We are producing too much trash. This is polluting the land, the rivers and the oceans, too. What should we do to protect our environment? We should save water and electricity. We shouldn't leave our trash in the country. We should collect used paper, bottles and cans. We can recycle them to save the natural resources.

Waste chemicals cause air pollution.
