Pollution is changing the structure of earth’s atmosphere resulting in the greenhouse effect and ozone depletion. As the oceans warm up and expand, the sea levels will rise. The most obvious effect of climatic change will be on agriculture. A warmer climate is likely to move the areas for growing specific crops such as wheat towards poles. Marginal agriculture will suffer most as it will be unable to adapt easily to new conditions.

Several chemicals used in or produced by industry greatly affect the speed at which the ozone is broken down. These include the chlorofluorocarbons. Changes of a few per cent in future ozone levels would be enough to let substantially more ultraviolet radiation reach the earth’s surface. Ultraviolet radiation is responsible for sunburn, slow blindness, eye damage, skin cancer and the ageing and wrinkling of the skin. It affects plant growth, slowing down photosynthesis and delaying germination of many plants including trees and crops. Algae are particularly sensitive to ultraviolet radiation raising fears that damage the ozone layer which could upset marine ecology and lower fish populations.

Noise pollution is a major source of population in the city. This is caused by the horns of buses and Lorries, the loud noise of engines and the high pitched sound of motor bikes. Loud speakers are also responsible for noise pollution. They are found everywhere in the cities. They are used for marriage function, festivals and public meetings. The automobiles cause air pollution also.

Air pollution is possibly causing disease, death to humans, damage to other living organisms such as food crops, or the natural or environment. The atmosphere is a complex natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has been recognized as a threat to human health as well as to the Earth’s ecosystems. Indoor air pollution and urban air quality are listed as two of the world’s worst toxic pollution problems in the 2008 Blacksmith Institute World’s Worst Polluted Places report.[1] According to the 2014 WHO report, air pollution in 2012 caused the deaths of around 7 million people worldwide.

There are various air pollution control technologies and land-use planning strategies available to reduce air pollution. At its most basic level, land-use planning is likely to involve zoning and transport infrastructure planning. In most developed countries, land-use planning is an important part of social policy, ensuring that land is used efficiently for the benefit of the wider economy and population, as well as to protect the environment.

Pollution control is the control of emissions and effluents into air, water or soil. Without pollution control, the waste products from consumption, heating, agriculture, mining, manufacturing, transportation and other human activities, whether they accumulate or disperse, will degrade the environment. In the hierarchy of controls, pollution prevention and waste minimization are more desirable than pollution control. In the field of land development, low impact development is a similar technique for the prevention of urban runoff.
