WATER BEING POLLUTED BY TOXIC CHEMALS
When we se smoke,we know that the air is polluted. When water changes colour, it is clear that it is contaminated.When the soil does not yield crops ,it is barren land. High level of noise troubles us. It is noise pollution. In other words, pollution refers to the changes in charecteristics of air ,water and land that are unacceptable.These changes affect plants , insects, birds, animal and human health. As the use of atural resoures increases,waste increase and pollution increases too . this is because waste is a by product of the use of natural resources.Wastes damage the enviroment after an extent, and turn into pollutants. Thus we can say that overuse of natural resources leads to pollution.Modernisation, industry, machines and transport have speeded up the consumption of all natural resources. The resultant pollution has affected air, water, soil, and life on the earth, chemically,physically and as far as human beings are concrened, even psychologically. Our world today is affected by different kinds of pollution. Air, water, soil, noise, waste and heat radiation are a result of speedy consumption of natural resoures.
Depending upon the form of matter, if there is smoke in the air it is air pollution; when water changes its colour,taste and gets dirty, we call it water pollution. If the soothing sounds/music turns cacaphonous and unbearable, we call it noise pollution. When heaps of solid waste gets accumulated, it is pollution from solid wastes. If there is excess heating up in an area we call it heat radiation. When the soil turns barren loosing all nutrients orwhen salts or acids accumulate in it, it is soil pollution.W hile some pollutants degrade into the soil on their own , others don’t.Some pollutants do not degrade on their own immediately.Some of them degrade over a period of time.Some pollutants do not degrade on their own but when treated can turn harmless.Some pollutants cannot be made harmless with any process.
When wastes exceed a limit , they damage the environmenmt and pollute it. It is comparable to adding too much salt to our food.The high salt content in food can be refered to as pollution in it .
About 60 years ago, a drop of phenyl was added to a bucket of water taken to clean the floor.20 years later, a tea spoon full was added or used. At present ,there is no dilution at all, now any disinfectant/germicide is being used directly,without dilution.This is not protecting but affecting human and aquatic health.Such excess use of chemicals leads to pollution.
Yet again, 60 years ago the bicycle was the most common vehicle. Now petrol and diesel guzzling vehicles zip around on our roads polluting our town/city air.60 years ago solid waste was very little, and it is disintegrated into the soil easily,mostly by itself.Presently with most waste being plastic it’s strangulates the soil.Alongside, the soil has lost fertility due to the over use of chemicals.This is how our rural environment stands degraded today.
