To protect and conserve the biodiversity, the government set up rules, methods, and policies and created protected areas such as wildlife sanctuaries, national parks, biosphere reserves, etc. Plantation, cultivation, grazing, cutting trees, hunting, and poaching are strictly prohibited there. The natural processes of plants protect our planet and supply the air we breathe and the water we drink. Plants prevent soil erosion and desertification. Plants provide the raw materials for food, clothing, medicines, construction and many other products that sustain our lives. It is necessary to conserve plants and animals to protect our environments. It also essential to protect animals because nowadays many animals like tiger, panda, etc. are becoming extinct; also conservation of plants is so important to control air, land and soil pollutions and cutting of trees should be protected.
