mark me brainlist.
Out of all the elements found on this planet, trees account for the sustainability of a large portion of the environment. Occupying vast extents of land in forests, nature parks and wildlife sanctuaries, trees purify the atmosphere with oxygen. All forms of life depend on their direct and indirect needs on the resources provided by trees. Large industries and organizations derive their raw material in the form of wood, paper, fibers and timber obtained from trees.
While producing these materials is of utmost importance, it is equally important to preserve the balance in nature. Excessive deforestation or the cutting down of trees to suit different needs can threaten the future of life on Earth. As the number of trees is reducing every day, pollution levels are increasing. With this, soil erosion and global warming have also reached their peak of risks.
