Trees bring big benefit not only the planet Earth, but also to all its inhabitants including to the person. People widely use wood for production of various objects. Besides, trees are living beings, it is important to them to grow and develop, they have just the same right for living, as the person.
Trees differ from each other just as people. Some of them grow in the dense forest, for all life will not meet human beings, animals treat them with respect, and they live long life among other trees. Others grow in the cities: "breathe" all what pollutes city air, low growing branches it are broken off by children, and municipal services are considered whether not to cut such tree which stands in light to residents of first floors of the house. Very seldom people take the valid care of trees though trees deserve it. They are very useful, not for nothing say that it is easy planets. They are suited so that carbon dioxide which trees absorb is necessary for them for activity, instead of it emitting oxygen. This process is called photosynthesis. If not trees, then the atmosphere of Earth it would be exhausted long ago not to mention that very many living beings could not live on it as they would have be nothing to breathe. Over such places of the planet as Antarctica and the Arctic where there are no green plants, an ozone layer rather thin therefore solar wind is capable to get through the atmosphere, causing the increased radiation level. Some types of sunlight are not too useful to living beings, and only the oxygen atmosphere prevents them to extend. And it is formed by trees. Also they promote that the soil was not washed away. They serve as the house and a shelter to many living beings among whom birds and insects. Some mammals lodge in hollows of trees, and others quietly move on them, escaping from predators which go on the ground. In the cities the trees not only produce oxygen, they also purify air as all dust accumulates on leaves, they absorb the various substances not too useful to human health from the atmosphere and accumulate them. On the basis of trees the ecosystems consisting of animals, birds, insects and other plants are formed. The woods consist of separate plants, and it is very important to keep them, otherwise activity of all live is broken. Also trees are very beautiful. Simple walk in the woods or on the park gives to the person of force on coping with many vital difficulties. Quiet and wise, these plants as though do not depend on time at all, and difficulties which podstegat all living beings continually, apparently, them do not concern. Looking at grandeur of trees, any person is capable to calm down and have a rest soul.
