Pollution is the introduction of contaminants into the natural environment that cause adverse change.Pollution can take the form of chemical substances or energy‚ such as noise‚ heat or light. Pollutants‚ the components of pollution‚ can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point source or nonpoint source pollution.

Soil Degradation The damaging process of soil particles being moved and cycled by water or wind is known as erosion. Soil erosion can occur anytime soil is bare or exposed and naturally removed by wind or water. This form of soil degradation is a natural process but it further elevated by human activity. Human disturbances of the soil allow for this process to happen more rapidly under natural conditions. According to the University of Michigan‚ whose geologist conducted a study‚ human actions

What is soil erosion? Soil erosion is a natural process‚ occurring over geological time‚ and indeed it is a process that is essential for soil formation in the first place. With respect to soil degradation‚ most concerns about erosion are related to accelerated erosion‚ where the natural rate has been significantly increased mostly by human activity. Soil erosion by water is a widespread problem throughout Europe. Soil is naturally removed by the action of water or wind: such ’background’

Soil conservation includes all such measures which protect the soil from erosion and restore its fertility. These measures are of two types-(a) small measures to check soil erosion at local or even individual level‚ and (b) large measures at government level involving larger area and heavy investment. (a) Small Measures-These include afforestation‚ regularised land strip cultivation or contour farming or terrace farming in hilly areas‚ use of stubble mulch system‚ increasing cohesiveness of the

While the nature takes from 100 to 400 years to build one centimetre of top soil‚ man can and often does destroy it almost overnight by haphazard land use and improvident husbandry. Irrational methods of cultivation‚ deforestation‚ destruction of natural vegetation due to overgrazing by pasturing animals etc.‚ accelerate denudation.

environment! Nowadays the society has to face up to a lot of problems. Among them the pollution is one of the most popular topics. People generally don’t think of it that they injure their environment with almost every action and this carries consequences. With few exceptions they can be solved. There are several ways of the environmental pollution. The most frequent question is the air pollution because the different gases appear everywhere: in the most beautiful countries‚ in villages

perfectly maintained. Then why do we fail to keep our environment clean; maintenance of which is far more vital as compared to our home? The term pollution means addition of any substance which alters the quality of the environment. Substances which cause pollution or alter the natural quality of the air‚ water and soil are called pollutants. Hence‚ pollution may be defined as the ‘contamination of the environment that causes harm to the health and survival of humans and other living organisms’. Therefore
