  Deforestation: Cutting down trees and elimination of forests leads to disturbance of the natural habitat
                 of living organisms. We all know that plants and trees are one of the major factors that cause rainfall
                 and disturbing them leads to scanty rainfall which in turn causes water crisis. The percentage of fresh
                 breathable natural air, and quality of air is also decreasing at an alarming rate. It leads to various unusual
                 climatic changes that are not in accordance with the natural cycle.




















                Mining: The process of digging the earth for the extraction of the ores results in erosion, formation of
                 sinkholes, and contamination of soils that cause severe damage to the environment. It disturbs the natural
                 living and breeding place of various living organisms and the life of people residing in the nearby areas. It
                 leads to soil erosion, landslide, noise pollution and contamination of surface and groundwater due to the
                 chemicals released during the extraction process.


















                Pollution: It is the contamination of the environment (land, air and water) due to the presence of some
                 unnatural  elements  i.e.,  pollutants.  Pollutants  are  harmful.  It  can  be  in  solid,  liquid  or  gaseous  form.
                 For example Poisonous gases emitted from factories   vehicles, chemicals   garbage dumped in the
                 waterbodies, excessive sound of vehicles, etc.  oise pollution is caused due to the sound generated
                 by Industrial   Constructional activities, factory equipment, generators, electric saws, drills and other
                 machinery.
