Nowadays there is a lot of talk about the pros and cons of cutting down trees.Wood is used as fuel, raw materials, building material, paper is produced from it, the bark is used for the production of fertilizers. These are the advantages of cutting down trees.The forest is a large area of plantations, trees and other plants that perform the function of absorbing carbon dioxide, processing it and saturating the air with oxygen. The forest is the habitat of almost all animals, as well as the source of their existence and nutrition. Destruction of forests leads to deprivation of the main source of oxygen, to the reduction of populations and even to the disappearance of species of animals, birds and insects. These are the disadvantages of cutting down trees.I believe that it is necessary to create specially designated areas for cutting. Then we will be able to preserve natural forests, and at the same time use wood for industrial purposes.
