Deforestation and Reforestation

Deforestation is the clearing of forests to use the land for cultivation, building houses and factories, making furniture, and the construction of dams, or for using wood for fuel.Cases where human beings are responsible for deforestation are known as man-made causes, while cases such as forest fires are known as natural causes.Other causes of deforestation include forest fires, severe floods and severe droughts.For the survival and well-being of the human species, a vast variety of plants and animals exist on the earth.
A consequence of deforestation is global warming that has a severe impact on the environment.Reforestation means planting new trees in destroyed forest area.Carbon dioxide released into the atmosphere traps sunlight reflected by the earth’s surface, and results in an increase in temperature levels on the earth.

This increase in the temperature levels is called global warming.It is advisable to replant trees of the same species that are found in a forest.In India, we have the Forest Conservation Act, which is aimed at preserving and conserving natural forests.Significance of the recycling process of paper - Used paper is sent back to the factories for recycling, after the recycled paper has been used, the amount of waste paper being disposed off would be much lesser.It takes 17 fully grown trees to make one tonne of paper.Even harmful chemicals are used in making paper.Trees are cut down and the wood is taken to a paper factory for producing paper.The paper that is produced is then sent to towns and cities for use.
