EASSY ON POLLUTION WITH QUOTATIONS FOR CLASS 10 & 12
POLLUTION
“Now our biggest environmental problems come from our own actions, our own choices, rather than pollution produced by big business.” (Jesse Ventura)
Pollution is the addition of any substance or form of energy to the environment at a rate faster than the environment can accommodate it by dispersion, decomposition, recycling, or storage in some harmless form. It also means to contaminate. It is the bitter fruit of over industrialization which is adding poisonous and lethal element to environment. We are adding certain things into our atmosphere which causing harm to our environment. We boast of having made Astonishing growth in different fields of life but after paying a heavy price. The speed at which we are mixing these pollutants is alarmingly fast. Pollution spares no one. It ruins everything: human beings, birds, beasts, marine life, soil , air plants. It can pose a threat to the future of mankind as well.
"Sooner or later, we will have to recognise that the Earth has rights, too, to live without pollution. What mankind must know is that human beings cannot live without Mother Earth, but the planet can live without humans."
There are a number of things which are causing pollution. The chief contributors to pollution are: Industry which is adding poisonous chemicals and gases into our atmosphere. Soil and Air both are badly affected by these harmful chemicals. Pollution continues to increase as a result of the increasing number of motor vehicles on the roads. Exhaust fumes from the engines of automobiles contain a number of polluting substances.
"We abuse land because we regard it as a commodity belonging to us. When we see land as a community to which we belong, we may begin to use it with love and respect."
Most of the substances that are harmful are: carbon monoxide and a variety of complex hydrocarbons and nitrogen oxides. When exposed of sunlight, these substances undergo a change in their composition. As a result the substances produce the brown, toxic and smog. All our big cities are the good examples of this smog. Other wastes also play their role in causing pollution like atomic waste, the use of pesticides, and smoke from the brick kilns, fertilizers, polythene, stinking smells and obnoxious fumes. All these are polluting the soil badly. Soil is the natural body made of mineral and organic constituents. It is produced by solid material recycling and complex processes of solid crust modifications.
"We say we love flowers, yet we pluck them. We say we love trees, yet we cut them down. And people still wonder why some are afraid when told they are loved."
Soil offers shelter, habitat for numerous organisms and is the living medium for plants. Soil is the basis for agriculture. All vegetation for human food and animal feed depends upon soil. Enormous quantities of waste from man-made products are being released into the soil causing soil pollution. Polluted water also caused soil pollution. Soil pollution is caused due to unhygienic habits, agricultural practices and inappropriate methods of disposal of solid and liquid wastes. Soil pollution is also caused as a result of atmospheric pollution.
"The most alarming of all man's assaults upon the environment is the contamination of air, earth, rivers, and sea with dangerous and even lethal materials. This pollution is for the most part irrecoverable; the chain of evil it initiates not only in the world that must support life but in living tissues is for the most part irreversible. In this now universal contamination of the environment, chemicals are the sinister and little-recognized partners of radiation in changing the very nature of the world-the very nature of its life."
Rachel Carson
Air pollution is a problem that everyone should be concerned about. With the growing number of automobiles, and the greenhouse effect problem is becoming more and more of a threat, air pollution is something to be concerned with. Air pollution involves the release of gases, finely dissolved solids, or liquid aerosols into the atmosphere at rates that exceed the capacity of the atmosphere to dissipate them or to dispose of them through incorporation into solid or liquid layers of the biosphere. Dust storms in deserts and smoke from forest and grass fires contribute to air pollution.
"Air pollution is terrible for our children. Every single scientist, every single doctor will tell you the same thing: Air pollution damages our children’s brains, their hearts, and their lungs."
We pollute almost everything useful in nature. Water pollution is the contamination of any body of water lakes, groundwater, oceans and even underground water is being polluted by raw sewage running into lakes or streams. Industrial waste spills contaminating groundwater and radiation spills or nuclear accidents.
"Water is one of the most basic of all needs - we cannot live for more than a few days without it. And yet, most people take water for granted. We waste water needlessly and don't realize that clean water is a very limited resource."
The noise pollution is loud sounds that are either harmful to humans and animals. Airplanes, helicopters and motor vehicles cause noise. Noise pollution can be disruptive to humans’ stress levels, may be harmful to unborn people, and drives animals away by causing nervousness and decreasing their ability to hear prey or predators. Human sight is also victim of pollution. Smoke and smog both are causing it.
"One of the great threats facing marine mammals in the ocean is acoustic pollution – noise pollution -which is impeding the whale’s ability to find food and communicate with each other."
The world in general and the developing countries like Pakistan need a whole hearted effort to fight against pollution. Public should be educated about the ravages of pollution and how it can be avoided. Efforts should be made to find alternative ways and means of energy like solar energy and other harmless sources of energy. It is a duty lying on our shoulders to leave a better world for our coming generations.
