Pollution is the introduction of harmful and toxic chemical substances in the natural environment. It can be naturally occurring contaminants or foreign substances. With industrialization and growth in population there has been increase in pollution in the atmosphere. The air, water and soil have been severely polluted by human activities. Our ecosystem is affected by pollution in number of ways.
Effects of Pollution on Ecosystem
Ecosystem is the natural system made of diverse species in its physical environment. The natural ecosystem is highly diverse and complex in nature. The toxic chemicals in the atmosphere spread widely throughout the ecosystem. It affects the soil, plants and other organisms, both directly and indirectly.
Ozone hinders the process of photosynthesis in plant species. Ozone gets dissolved in plants and reacts with chemicals that cause number of problems. The process of photosynthesis slows down which results in slower plant growth. The primary ecosystem function such as plant growth and biogeochemical cycling is affected by contaminants in the natural environment which affects the ecosystem services.
Ecosystem refers to the interaction between various organisms, plants, animals, fungi and bacteria. They form the entire food web where each depends on the one below it in the food chain. When the ecosystem gets polluted the natural balance in the ecosystem gets disrupted which effects different organisms in different ways. The pollutants like oil, nitrogen, detergents and phosphate can have negative impact on ecosystem especially if the water gets polluted. It can damage the ecological balance by adversely affecting the marine life. Thus, pollution hinders the natural cycle of ecosystem.

Addition of harmful substances to nature is called pollution. Pollution is of different types. The smoke coming out from the chimneys of industries and the silencers of vehicles cause air pollution. We can check this by reducing the polluting factories and using good quality fuels and engines. Now we can plant trees which will convert carbon dioxide into oxygen. We have to develop and use solar power to reduce air pollution
Water pollution is caused by leaving untreated industrial wastes directly into rivers, tanks and lakes. This should be avoided by all means. The wastes must not be discharged into rivers directly. The wastes should be treated in a proper way. Ocean water is polluted by leakage of oil from offshore oil wells and during movement of ships. Proper measures and care should be taken to check the leakage of oil.
When we throw plastic wastes and other under gradable wastes, it causes soil pollution. Soil pollution makes the soil infertile. Most of the people in India are dependant on agriculture. Hence, soil pollution should be avoided if we want the farmers to progress.
Noise pollution is caused by industries, honking of horns, using loudspeakers and bursting crackers. We should avoid using horns near schools and hospitals. We should not use loudspeakers after 8 pm and loudspeakers’ sound should also be minimised. Bursting of crackers also should be controlled. Pollution affects the health of all living beings. All sorts of pollution, spoil the ecology and that should be avoided.
