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.
