Impact of pollution on Ecosystem

Modernization and industrialization has its adverse effect on environment surging toxins and health hazardous chemicals in both biotic and abiotic components of environment. Undoubtedly machines have made life super easy but it has taken a toll on human civilization.  World is facing many environmental issues wherein presence of pollutants in environment is being one of the major issue.

Pollutant is elements, unwanted particles and chemical and toxin present in atmosphere. Pollution is referred as presence of these pollutants in biotic and abiotic components of atmosphere. Both Biotic and a biotic component of atmosphere built our eco system. Abiotic is presence of all non- living and physical component  of atmosphere required to balance the eco system like water , air, natural gas etc. whereas biotic is all living organism present in eco system like humans, plants, bacteria etc.  These components are essential to maintain a balance in ecosystem.  It’s a impurity that is unwanted and is harmful to mankind and currently is major significant issues of the world.

Air pollution is one of the major pollution concerns existing in world and has raised an alarming situation. It is injurious to human health and the planet as a whole. Major causes are burning of fossil-fuels, coal, natural gases, industries, household uses, insecticide and pesticide and likewise.

Soil pollution is another major pollutant that is detrimental to humans and plants. Mixing of pollutants in soil has deteriorated its PH value causing to have it unfertile and barren. Illegal mining, dumping of urban and industrial waste, has resulted in soil erosion.

Water pollution is mixing of waste from factories, homes in water bodies. Mixing of pollutant make water contaminated and resulting in deletion in quality of water.  Heavy metals like lead, iron and arsenic is found in water making it poisonous for both terrestrial animal and aquatic. Last but not the least is noise pollution.  It is continuous exposure to an extreme sound level that causes annoyance and irritation. Sound levels less than 70 dB is tolerable by living organism and above that can affect respiration, headache nausea, according to World health organization.

Human activities that create pollution and affect environment

Pollution has disturbed the ecosystem to much extent.  Ecosystem chain has been adversely affected by climate change. Depletion ozone layer – ozone layer prevent entry of harmful sun radiation to the earth.  But toxic gases like carbon tetrachloride and methyl chloroform is leading its depletion.

Various examples in both world and India

Almost 90% of world population lives in areas where level of contaminated gases and fine particles have exceeded the limit according to WHO. Worldwide an estimated 6.5 million deaths (11.6 per cent of the total) were associated with indoor and outdoor air pollution in 2012, according to the WHO.

India is developing economy of the world and is growing rapid in recent years. With these recent developments of infrastructure, industrialization has increased pollution revelation the rise of toxicity in air and water. Many parts of India have witnessed acid rain making lad barren for further use. approx.25% of global deaths attributes to hazardous particulate present in the air.
