Atmospheric pollution as a result of emission of carbon monoxide, Sulphur oxides and hydrocarbons has become a subject of growing concern and has led to increasing pressure for restrictions of burning of fossil fuels.
It is estimated that currently more than 20 billion tons of carbon dioxide are being released in the atmosphere in this way every year. The discharge of these air pollutants is infecting and destroying river, lakes and oceans. Air, water and soil are harmed by pollution, these things are necessary for the survival of living things. Pollution in air causes various diseases of lungs and various other illnesses. Polluted water kills fishes and other marine life. Pollution in soil decreases the fertility of soil.
Pakistan has high rate of population growth. The increase in population results in more and more industrialization. Factories gives of smoke and chemical poisons are also wasted in the water that cause various diseases related to digestive system. All these kinds of pollutions are means of destroying river and marine life and endanger animals, plants and human life.
These factors are promoting global warming and make our future life more threatens. We should plant more trees and save our environment. Trees make the oxygen and spread it in the air for us. Strict policies should be made for factories so that they are not allowed to discharge chemical wastes into the water.
The factories should recycle their waste product in order to reduce pollution. Those vehicles should not be allowed to move on the road that spread harmful smokes. Government should play their role to reduce pollution and make environment friendly policies. Scientists and engineers should also play their role to reduce pollution. Pollution causes different types of diseases. Air pollution causes allergies asthma lung cancer and bronchitis. Radioactive pollutants cause respiratory problems paralysis cancer and other disease.
Excessive noise pollution can lead to deafness anxiety stress increase in the rate of heartbeat and other health problems. In order to fight this menace of pollution vigorous efforts should be made the anti pollution law should be strictly implemented.
In order to check water pollution sewage and the factory waste should be planted everywhere and vehicles should be made eco friendly. Public education and awareness of the relationship between climate change and human health is a key to deal with these problems more effectively. General awareness is a must to save our planet from destruction. A ll the nations of the world should work united to control environmental pollution.
Plato lamented the destruction of soils and forests in ancient Greece. Dickens and Engels wrote eloquently of the wretched conditions spawned by the Industrial Revolution. But the surge in concern about environmental quality over the last three decades has been uniquely widespread and impassioned. Appreciation of the material and spiritual importance of a healthy natural environment has spread. Perhaps the most dramatic intellectual shifts are occurring in the Third World, where understanding of the ecological under spinning of human life-largely lost in the post-war dreams of industrialisation is on the rise.
The new interest in environmental quality complements recent shifts in thought among development theorists, many of whom now stress the need to address the basic needs of the poor directly rather than hope that the benefits of growth will trickle down to them. Improving the lot of the under-class and protecting environmental quality can be mutually-supportive goals.
Both internationally and within nations, the new appreciation of our bonds with nature has spawned new institutions and policies-new UN and governmental agencies, new laws, altered aid programmes, new international treaties.
Yet for the most part, responses remain inadequate to the needs. For the most urgent need today is to protect and preserve what remains of the environment.
To do that one has to understand the meaning of pollution and consider ways of tackling it. It takes place through changes in energy patterns, radiation levels, chemical and physical constitutions, and abundance of organisms. It includes release of materials into atmosphere which make the air unsuitable for breathing, harm the quality of water and soil, and damage the health of human beings, plants and animals.
Air pollution in one form or another has accompanied human society from the beginning. In the nineteenth and early twentieth centuries, many cities of Europe and the US were covered with black shrouds of smoke.
Despite the successes registered against smoke, the pollution of city air by other products of coal combustion above all, Sulphur dioxide and by nitrous oxides, hydrocarbons, petroleum wastes, and carbon mon.
Strong evidence indicates that prevailing levels of air pollution contribute to the development of chronic respiratory diseases emphysema, asthma, and chronic bronchitis besides short-term respiratory afflictions as well.
And those living near smelters and refineries often face increased cancer risks because of the toxic substances spewing from smoke-stacks. Over the last 25 years, many countries have begun trying to regulate the flow of pollutants in the air, Air pollution can no longer be addressed as simply a local urban problem.
Thermal pollution of water. In general, pollution from so-called point sources like sewage pipes and factories is under progressively better control. But the contamination of waterways from diffuse sources-run-off from farmlands which tends to carry fertilizers, pesticides, and organic matter, and from urban areas, which often carries oil, metals, and other pollutants-remains largely uncontrolled and is on the increase in most countries.
Acids and heavy metals falling with the rain constitute additional sources of water degradation. The problem of water pollution is growing day-by-day; today a great many people are deprived of disease-free potable water, as almost all the sources of water-from seas to wells-are increasingly being infested with different kinds of pollutants.
Soil pollution usually results from the disposal of solid and semi-solid wastes from agricultural practices and from insanitary habits. Fallouts from atmospheric pollution also contribute to soil pollution. Direct pollution of the land by pathogenic organisms is also important. Thus the soil is heavily polluted day-by-day by hazardous materials and micro-organisms, which enter the food chain or water and are consequently ingested by man.
As a result, there are numerous health problems. Those bacteria which are transmitted from air to soil infect man causing bacillary dysentery, cholera, typhoid and paratyphoid fever. Flies which breed or get in contact with the contaminated soil become carriers of disease organisms.
The eggs of some of the parasitic worms get incubated in the soil and both the eggs and larvae are infective. Radioactive pollution of the environment is due to the increase in natural background radiation, emerging from the activities of man involving the use of naturally occurring or artificially produced radio-active materials.
The chances of radioactive materials Spreading into the air have increased extensively as a result of the discovery of artificial radio-activity, and particularly due to the development of atomic bomb and of techniques of harnessing nuclear energy. Biological organisms including human beings are subjected to radioactive contamination either by consumption or inhalation. Chronic exposure to radiation leads to leukemia in an individual and affects even an unborn child.
Thermal pollution denotes the impairment of the quality of environment air or water by a rise in its temperature. The processes of life involve many chemical reactions, and the rate of these chemical reactions vary according to the changes in temperature.
Apart from biochemical reactions, temperature is considered vitally important to physiology and in controlling reproductive cycles, digestion rates and respiration rates. The effects of thermal pollution are mainly seen on aquatic animals, particularly fish, on whom the human society so much depends. The modern world has a new pollution to face-that of noise.
The scientific approach for considering noise as a pollutant is by decibel. Apart from industrial noises the sources generally are loudspeakers, motor vehicles, trains, aircrafts, processions and rallies.
Noise need not just lead to deafness. Research has shown that noise pollution is capable of causing ulcers, abortions, cardiovascular diseases, congenital defects and hypertension. The first and most important cause of pollution is the growing population. The earth is now crowded with people, and all of them consume resources and create wastes.
If the per capita amounts of pollutants and wastes were to remain constant, the residue loading of the environment would rise precisely in relation to the growth of population.
This is acceptable within certain limits, given the capacity of air, water and land to absorb, dilute, carry away and otherwise render pollutants harmless. But, unfortunately, in many places these limits have either been reached or have been exceeded.
Another important factor is the rapid industrialisation and haphazard urbanisation all over the world. The natural processes which keep the planet habitable in the short-term are primarily cyclic. Materials moving through these cycles utilise solar energy and return to their original state before other processes start.
In contrast, modern technology causes materials to be removed from the limited geological deposits or from living systems to be eventually discharged as wastes. Not only do these wastes act as pollutants of the natural cycle but they also alter the composition of the atmosphere and disturb the balance of solar radiation. The ability of the biosphere to withstand these stresses is further decreased by such conversion of complex natural ecosystems to simple ones.
Haphazard urbanisation makes it quite difficult to provide and maintain the required civic amenities. Some cities have become so large and so crowded that the municipalities fail to properly maintain the sewage, provide clean drinking water or adequate garbage removal facilities.
The deterioration of natural systems in poor and marginal areas is at once a symptom and a cause of the extreme misery in which hundreds of millions live. The pollution problems cannot be isolated from questions of economic progress, political stability, social awareness, migration and international aid. Indeed, many types of localised environmental degradation have global implications.
To some degree their causes are also international. Through their way of life and the behaviour of their multinational corporations, citizens of the North can affect environmental conditions in the South. More important, the extent of the extreme poverty that gives rise to so much ecological damage and human suffering is influenced by international monetary, trade, technological and aid policies.
The struggle to preserve global environmental quality is unavoidably intertwined with the struggle to improve the lot of the global under-class. The problems are rooted in the society and the economy-and in the end in the political structure, both national and international.
Foresters know how to plant trees, but not how to devise methods whereby villagers in India, the Andes, or the Sahel can manage a plantation for themselves. Biologists know where to draw boundaries for nature reserves, but cannot keep landless peasants from invading them to grow food or cut fuelwood. The solutions to such problems are increasingly seen to involve reforms in land tenure and economic strategy, and the involvement of communities in shaping their own lives.
Applying sensible pollution control faces inherent political and analytical difficulties. The direct expense of clean-up measures, falls upon particular industries or groups, while the resulting benefits, even if much large, are less visible and are spread widely in society. The costs of required controls are tangible and easily figured, but no ready means exist for totalling the benefits of pollution reduction. The temptation is to engage in extremely narrow accounting, ignoring the immeasurable, subtle benefits of a cleaner environment.
The affected industries have a strong vested interest in opposing the required investments, while no single group has an immediate material interest of comparable magnitude in imposing controls. Thus the political process is distorted, resulting in anti-pollution policies weaker than what is demanded by social interest.
No objective means exist for ascribing value to all the costs of uncontrolled pollution, or to the benefits of reducing it. What is the price of a shortened human life? How does one evaluate the spiritual loss of the residents of Tokyo whose sight of Mount Fuji is obscured by smog?
How can we measure the value of a restored and productive ecosystem? The dual judgement about the desirability of anti-pollution measures, then, is inescapably a political one reheating value choices. No economist alone can supply answers to the great environmental policy issues of the day. No doubt, the problems are many and complex even as pollution is growing unbridled. But a failure to control pollution carries and enormous price in the form of bad health and premature deaths of human beings, other animals and plants; losses of productive ecosystems such as fisheries; losses of recreational opportunities; and degradation of the aesthetic quality of life.
People are gradually losing even the freedom to breathe safely. The all-round depletion is making this planet inhospitable and uninhabitable. Because of the growing pernicious effects of pollution. The Rio Summit on environment is a great landmark in this direction, though, of course, we have to wait for some time more for any tangible results.
The importance of clean environment and the detrimental effect of pollution have been realised in India as well. Several legislations exist to control pollution and conserve the environment, with the Environment Protection Act of being the landmark law. But unless the legislations are enforced with sufficient political will, they are rendered useless. Greater participation of the voluntary organisations and an effort to educate the masses on environment and pollution can help to make the Acts effective.
If the costs were distributed fairly through society, the antipollution struggle would place no serious burden on anyone. Environmental choices must be guided by a vision of a desirable human society and of the quality of the natural environment needed to support that vision.
It is an established fact that our metro cities are not good enough to live in. The noise of ever —increasing number of vehicles does not allow us to sleep even at night. All our important cities have been found to be the worst polluted cities in the world. In order to overcome the problem , it is important to identify the sources of pollution.
The major source of pollution in the cities is the heavy traffic on the roads. Buses, cars, motor-cycles and other such vehicles emit carbon mono-oxide, which badly affects our lungs,. In fact, sometimes, it becomes difficult even to breathe because one can feel the heavy air that one is inhaling.
Another source of pollution is the smoke from the factories, running in residential area. Another reason of too much pollution is the absence of plants and trees. Cutting down of trees indiscriminately everywhere for the sake of buildings has created the problem of survival itself.
Water is another essential necessity which, again, we get in a highly polluted form. It is easy to isolate the sources of pollution here also. One reason is our age- old superstitious belief in ancient customs which leads us to make the water filthy. Ashes and left-over bones, after the cremation of the dead body of a friend or relative, are also thrown into these and other big rivers.
It never comes to our mind that the cities through which these rivers are flowing, receive their water supply from them. Yet people can be seen washing their dirty clothes with impunity on the banks of these rivers which further contaminates the water. As if all this is not enough, effluents from industries are also released into the rivers and these further aggravate the problem. Yet again, the pipes through which the water is supplied to us are often old and rusted.
The aftermath of all this pollution of air and water is really deadly for all those living in cities. Air pollution leaves no pure air to breathe in and these results in a host of diseases life suffocation, breathlessness, asthma and migraine.
The body remains deprived of its required supply of oxygen and thus we feel too weak to work efficiently. This is why our cities are filled with pale, anemic — looking adults and children, for the blood deprived of the life-giving oxygen, absorbs the toxic gases present in the atmosphere. Water pollution is also highly harmful.
Even heavy chlorination shows no beneficial effects and the level of pollution remains above the acceptable norms. No wonder, epidemics life cholera, typhoid, hepatitis and other such water — borne diseases regularly attach the masses. Further, the dust, which can easily be seen, if the water is collected in a vessel and left standing for some time, results in the bladder and kidney problems.
The most urgent need of the hour, therefore, is to have an effective check on the pollution problem, if we are to escape being a nation of sick and unhealthy citizens. This is possible only when individuals and the government are serious enough about remedying the situation and make quick, joint efforts. A number of steps are to be initiated to get rid of the air pollution in cities.
All of us should maintain our vehicles well so that only the minimum amount of fumes is emitted. The government can take a strong view of it and penalize the offenders heavily. If there are frequent checks, they are sure to yield positive results. Wherever possible, trees and plants should be planted this will convert the carbon —di- oxide in the atmosphere in to life-giving oxygen.
Likewise, stern and deterring steps must be taken to check water pollution. Dumping of rubbish at any point in any river has to be prohibited. To respect the religious sentiments of the people , certain areas could be cordoned — off for the ceremonial disposal of ashes etc. The results are sure to be highly rewarding, if mass involvement is encouraged. However, unless this is done on a regular basis, the problem is not going to e eliminated forever.
Epidemics of water —borne diseases would, then , be prevented from increasing at the source. The Problem of Pollution. For example the pollution of air is the contamination of pure air by the harmful agents like soot, noxious fumes by vehicles and industries.
Pollution of water by the harmful chemicals is another example of the pollution. Since the start of the industrial revolution, there has been a constant change in the composition of the air chiefly due to the burning of fossil fuels used for energy and transportation purposes. Air pollution is a chief environmental health problem. The effects of air pollution on health are very complicated. The chief sources of the air pollution are Suspended Particulate Matter SPM , carbon monoxide, volatile organic compounds, sulphur dioxide, oxides of nitrogen, volatile organic compounds produced by industries etc.
Besides that indoor air pollution can prove to be severely fatal to health as it is released in close proximity to the inhabitants. The fact that should be noted is that a pollutant released indoors is many times more likely to reach the lung than that released outdoors.
In the developing countries a fairly large portion of the population is dependent on biomass for their energy requirements. These include wood, charcoal, agricultural residue, and animal waste. These sources are used for cooking and heating and are commonly found in the household both in the rural and the urban areas. The stove is generally situated at the floor level, enhancing the risk of incidents. In addition, they are often not fitted with a chimney for the exhaustion of pollutant gases.
In such households the children and women are most likely to be affected, as they are the inhabitants that spends more time indoors. Common atmospheric pollution sources and their pollutants are listed below: Fires are also among major source of air pollution and can lead to severe problems.
These fires can either be forest fires, oil well fires, burning of leaves in the backyard or as in the case of rural areas, large-scale burning of agricultural waste. Another main pollutant in this environment is the SPM.
In fact, death due to indoor air pollution, mainly particulate matters, in the rural areas of India are one of the highest in the world. Tobacco smoke generates a wide range of harmful. It is not new that smoking affects the passive smoker ranging from burning sensation in the eyes or nose, and throat irritation, to cancer, bronchitis, severe asthma, and a decrease in lung activity.
Biological pollutants mostly include allergens that can cause asthma, hay fever, and other allergic diseases. Volatile compounds can cause irritation of the eye, nose and throat.
They may also cause headaches, nausea, and loss of coordination. Long time exposures to lead can lead damage to the nervous system, digestive problems, and in some cases cancer. It lowers the resistance to colds and pneumonia.
The topic of “Pollution” or “Environmental Pollution” can be given to the students in their schools and colleges for essay writing on any event. RECOMMENDED ESSAY: Gender Equality Essay Pollution is the introduction of contaminants into the natural environment that cause adverse change.
