★ MEN AND POLLUTION

In recent years, man’s awareness about his environment has considerably increased. Man’s existence and well-being are intimately related with environment and its conservation. Environment stands for all that surrounds us and our planet Earth. It means all influences and circumstances that directly affect us and other living beings. In other words, our bio-sphere and eco-system constitute our atmosphere and environment. These sustain life on the earth.

The Earth is unique because of its environment which is life-giving and life-sustaining. On other planets like Mars, Jupiter etc., there is no life because there is no environment. Life has been possible only on our planet because of a certain balance in natural elements like air, water, earth, soil etc. Without this environment and its desired balance, our Earth would have been another dead and lifeless planet revolving round the Sun.

Of late our environment has been in great danger. There has been grave ecological crisis threatening the very existence of life. We have been destroying valuable natural resources and polluting the environment. And thereby have poisoned and polluted our own life and living. Any undesirable and excessive addition of substances which adversely changes this balance may be called pollution. These substances may be called pollutants. When this imbalance grows beyond a certain limit, it may prove fatal both for human and other living beings. And this imbalance, increasing rapidly and universally, has rung alarm bells. There is an urgent need to protect and conserve our environment.

The rapid and indiscriminate industrialization has quickened the process of environmental pollution. Our cities and towns are so full of smoke, noxious fumes, dust, rubbish, corrosive gases, too much loud noise and foul odors that they are no fit for human living. The burning of fuels and coal in factories and mills releases a great amount of sculpture oxide in the atmosphere. The heavy vehicular traffic has created grave pollution problems. The air in the urban areas is saturated with such pollutants as carbon monoxide, oxides of sculpture, nitrogen, hydrocarbons, pesticides, flashes, soot, and sometimes by radioactive substances too. These pollutants in the atmosphere cause a variety of serious human and animal diseases, and damage crops and plants. Aerosols etc., released into the atmosphere cause the depletion in the protective layer of ozone. The ozone hole detected over Antarctica a couple of years back was of the size of a football field. But it has now grown into the size of a continent. The consequences of such reckless and continuous depletion of ozone layer in the biosphere are bound to prove very dangerous. It is the need of the hour that something urgent, solid and substantial is done to restore atmospheric balance.

Raise is another great pollutant. The general noise level in the cities and towns has been rising alarmingly. It has resulted in loss of normal hearing-ability in many. Moose coming from buses, trucks, cars, scooters, trains, trams, aircrafts, factories, mills, power-houses, sirens, public address systems, radio, television, religious and social functions, and processions is already too much^ It has caused many types of serious physical and mental disorders. It has affected adversely our rest, sleep, and creativity, social and family behaviour.

The water of our rivers and oceans is polluted with much kind of effluents, industrial wastes, suspended solids, bacteria etc. The sewage has dangerously damaged the health of our various water resources like lakes, rivers, ponds, tube wells, canals and streams. These discharges contain a variety of poisonous effluents from factories, workshops, tanneries and colonies. It causes the spread of many water-borne diseases which may ultimately develop into epidemics. The detergents, fertilizers, pesticides, oil-spills etc., are other major sources of water-, pollution. Wastes from slaughter-house, dairies, breweries, tanneries, paper and sugar mills, chemical plants etc., has further worsened the problem. Like air and water, soil is also being polluted. It has decreased the productivity of the soil. Pesticides and artificial fertilizers have been identified as the main pollutants of the soil. They kill beneficial soil organisms and make the soil poisonous and toxic for plant-growth. Deforestation, overgrazing, cutting of trees for timber and fuel hove caused soil-erosion, droughts, floods and such other calamities on a vast scale.

Answer 2

Human activity is responsible for most of the world’s air pollution, both indoors and outdoors. Everything from smoking cigarettes to burning fossil fuels tarnishes the air you breathe and causes health problems as minor as a headache to as harmful as respiratory, lung and heart disease.

Types of Pollutants

Man is at least partially at fault for most of the world’s major air pollutants. Carbon dioxide is one of the most highly prevalent, comes from the combustion or burning of fossil fuels and other organic materials. Nitrogen oxide and dioxide, while both natural components of the Earth's atmosphere, occur in greater amounts due to human actions and are the cause of smog and acid rain.

Pollutants also include chlorofluorocarbons (CFCs), were widely used as refrigerants and aerosol propellants. These chemicals damage the ozone layer, which is why the Environmental Protection Agency banned them in 1978.

Pollution Effects

Smog is one of the most dangerous air pollutants to humans and other biological organisms. It is made when coal and oil containing minor amounts of sulfur are burned. The oxides of these sulfur particles form sulfuric acid, which is toxic to life and damaging to many inorganic materials. Air pollution can damage human life, especially in major cities where there is a conglomerate of industries and fumes from vehicles.

Pollution harms the living environment. Sulfur dioxide, nitrogen oxides and peroxyacl nitrates enter leaf pores and damage plants that way. Pollutants also break away the waxy coating of leaves that prevent excessive water loss, causing further damage to crops and trees that are important to the surrounding environment
