There are many kinds of pollution. Air, water, and land can be polluted. Some pollution is caused by nature, such as floods, forest fires, and volcanoes. People are the major cause of pollution. We pollute the air with our cars, homes, and factories. Smoke from factories and car exhaust makes the air looks gray and smoggy. Some people cannot go outside when the air is very bad! We pollute the water by dumping garbage and chemicals in the water. Plants and animals die because of the pollution in the water. We pollute the soil with chemicals and garbage. We harm the land by cutting down trees in the forest, especially to build roads and new houses without careful planning and thinking.
The only way to save our environment is to think about pollution. How can you stop or limit pollution? How do we protect our environment? Conservation is one way to protect our environment. Conservation is the wise use and protection of our environment. We can control water pollution by not producing as much waste and by proper disposal of sewage and garbage. We can take care of recreation land by cleaning up after ourselves and not causing more pollution. Carpooling and public transportation will help reduce air pollution.
Recycling is a type of conservation. Recycling is reusing items over again or in a new way. Recycling can help US conserve our natural resources so they will last many more years.
