So an ecosystem consists of both biotic(living creatures) and abiotic components like temperature, rainfall, wind, soil, etc. • Ozone layer: • The ozone layer is the outermost layer of earth composed of ozone gas which protects the earth from UV rays which causes cancer and other defects in living organisms. Ozone layer lets only some of the UV rays reach the surface of the earth. • ENVIRONMENTAL PROBLEMS • Changes in the environment affect us and our activities change the environment around us. Environmental problems caused by humans: • (a) depletion of the Ozone Layer and waste disposal. • (b) pollution due to mismanagement of waste disposal. • Reason of Ozone Depletion • Excessive use of CFCs (Chloro Fluoro Carbon) a synthetic, inert chemical E.g. Freon which is used as refrigerants and in fire extinguishers, caused Ozone depletion in the upper atmosphere. A single chlorine atom can destroy 1,00,000 Ozone molecules. U.N.E.P. (United Nation Environment Programme)did an excellent job in forging an agreement to freeze CFC production at 1986 levels (KYOTO Protocol) by all countries. • Prevention • For prevention from the depletion of the ozone layer, there is an organization (United Nation Environment Programme) in which most of the countries are agreeing to not to produce harmful gases that will damage ozone layer. • *** Top Apps from Toppr to drive Better Results:- Check Here:: • π± Toppr App link - https://play.google.com/store/apps/de... • βπΏ Get your homework answers here (Toppr Answr) - https://play.google.com/store/apps/de... • π Unlock your doubts with Toppr Plus - https://play.google.com/store/apps/de... • Welcome to Toppr Study!!
