Enviroment is the most important thing for our life. Environment is an essential part of our life. Nowadays, a variety of environmental problems affect our entire world.But now that most important thing for our life is being polluted. A clean environment is necessary for a peaceful and healthy life. 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,try to avoid buying plastic.To protect environment we also have to save energy:walk more, drive less, to conserver wild life, conserve the old forest, rainforest,to prohibit hunters who hunt wild animals out of the law.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.
