Our Earth is our home. People must take care of their Motherland. There are some laws an decisions on this important subject. We have state organisations which pay attention to this problem. The international conventions pay much attention to the control of pollution too. There are a lot of industrial enterprises in our country that is why we can't ignore the problem of the protection of our environment. Our main aim is the protection. Our environment must be clean. What must we do for it? We have to control atspheric and water pollution, to study the man's influence on the climate. The pollution of the environment influences the life of animals, plants and our human life. If we don't use chemicals in a proper way we will pollute our environment. The people all over the world do everything to protect their nature, to make their country richer, to make their life happier. If we are unable to learn to use the environment carefully and protect it from damage caused by man's activites,very soon we'll have no world o live in.
