Pollution is described as the introduction of different wastes into the environment. These material wastes are called pollutants. Pollutants may be either natural which is thrown away by natural disasters, volcanic eruptions or man-made trashes like factory washouts, plastic wastes. Pollutants are harmful as they damage the quality of natural resources such as air, water, and land. Pollutants mixing in the air have a direct impact as they enter the body directly while breathing. Pollutants that mix in water also creates a hazardous effect on people’s life. People residing near the construction and manufacturing work areas are diagnosed with relatively higher hearing ailments. This contributes to noise pollution. Similarly, there are varieties of pollution in our surrounding world, some of which are unaware of by us. The fact is, we humans are the ones creating all this pollution without thinking about neither our life nor the future world and life. It is very difficult to construct a zero-pollution world. Still, the level and consequences of pollution could be decreased by taking some measures and being more sensible.
TYPES OF POLLUTION
AIR POLLUTION – Increasing industrialization has paved the way for poisonous gases to enter the atmosphere. This in turn creates adverse effects like respiratory and other diseases in human beings. The carbon and its oxides released by the burning of coal and fossil fuels are absorbed by the trees. But as we started cutting trees to find areas for accommodation, these carbon oxides mix the atmosphere and pollutes it. The fresh oxygen we breathe thus gets contaminated and can give rise to many skin diseases and respiratory disorders like asthma, bronchitis, etc. These impacts could be decreased by following afforestation and reforestation and adopting the use of natural gases and biogas.
WATER POLLUTION – Introduction of industrial effluents, pesticides and insecticides, domestic waste, detergents, and fertilizers contaminate the water bodies. Water pollutants are released directly to the nearby water sources without proper treatment. These pollutants in water mix up with all the water bodies and finally contaminate the ocean by the formation of algae which creates a threat to aquatic life. It also generates unfavorable effects on humans and affects the food chain. It causes communicable and non-communicable diseases like cholera, typhoid, dengue, etc. This could be prevented by conserving water, treating sewage before it is disposed and use of eco-friendly products.
SOIL POLLUTION – Soil pollution refers to the existence of chemicals, toxic compounds, salts, and radioactive elements in the layers of soil. Discharge of toxicants from industries, stagnation of polluted water, heavy metals, and other solvents stay in the soil and make it infertile for cultivation. Due to this, the texture and quality of the soil are lost damaging the growth of plants and organisms living in the soil. Percolation of dirty water, dumping of fuels and oils, dumping of pharmaceutical and other medical wastes also adds to soil pollution. These influence humans indirectly through the plants that we consume as food. Industrialists should follow the environment protection norms strictly and individuals must start practicing the 3Rs – Reduce, Reuse and Recycle the to lessen soil pollution.
NOISE POLLUTION – This form of pollution is increasing and creating an unsafe environment. The increase in sound levels becomes dangerous for living creatures and causes several disturbances in society. An increase in industries, technology, use of vehicles, parties, bursting crackers, and loud political meetings contribute a lot to noise pollution. Unlike, other pollution, noise pollution can also bring about serious issues like hearing impairment and other troubles in the eardrums. Not only humans, but this kind of pollution also badly hits the wildlife. We must become aware of these unnoticed yields and help in building a safer and better society.
