Environment is an essential part of our life. But now that most important thing for our life is being polluted. When fossil fuels i.e. oil, coal and gas are burned to provide energy for cooking, lighting etc. they form polluting gases.In the sea, oils spills pollute sea water and kill marine life. Artificial fertilisers pollute river water, killing wildlife and spreading disease .Pollution could be prevented by keep clean environment .Use recycled paper to help save trees ,plant more trees ,to conserve wildlife ,to conserve the old forest, rainforest.When we protect the environment, it’s mean we are protecting ourselves and our future as well .I hope that in the future the earth will be cleaner .
