It’s a wonderful world we live in.But now human beings are killing our planet.Many species of animals and birds have disappeared because man has polluted their natural homes. Besides, every year people cut down more trees, build more roads, and use more land for farming.Human's activity destroys our planet, air, soil and water with poisonous foam caused by chemical waste, gases. It’s an international disaster. People cut down the trees, pollute the seas and oceans with litter.Pollution is very dangerous for people, wildlife and the environment.We live among litter and wastes which we have created ourselves – fumes of cars, throwaway packaging, etc.
