Задать 10 вопросов к тексту Since their emerging on earth, human beings immediately began to actively explore the environment. They used natural resources to produce their own food and water, to build homes, to sew clothes and to create tools. Naturally, because of this interaction with nature, reserves of wood, fresh water and minerals started to deplete, and some animals and fish as food for people began to disappear from the face of the Earth. In addition, the active pollution of environment occurs as a result of industrial development. Global warming, ozone holes, melting of glaciers are just few negative effects of human impact on nature. Therefore, today people do a lot to save it. In 1948, an organization called the International Union for the Conservation of Nature and Natural Resources was created. Today such activities as land restoration, wood conservation, creation of reserves and national parks, fishing restriction, limitation of emission of harmful substances, etc. are held in all countries under the control of this organization. There are various environmental actions organized by the society for the protection of nature every day. These activities engage people, who are not indifferent to the fate of our planet. For example, not long ago, in May 2015 year, Moscow hosted the famous campaign «Pant a Grove of Hundred Words». It was dedicated to the memory of the heroes of the Great Patriotic War. In honor of these people, various trees were planted in the natural-historical park «Serebryanyi bor». To take care of nature and to protect it is the duty of every human being. If each of us tries to do something small, for example, to plant trees, to clean streams of debris during out-of-town trips or to put stones on the river banks to prevent soil erosion, then maybe the people on Earth will live long in harmony with the world around them
