Pollution | A Threat to Environment

                                                                               Environment and Pollution 

No doubt humans are eradicating and disturbing the equilibrium of the environment. Our environment have all the necessary things which a living organism required, but what we are doing we are exhausting and making unavailable for others if not then for our future generations. Pollution is the main reason behind this because more over the pollution lesser is the growth of environment ( here I say 'Ecosystem').
Environmental Pollution
Relationships between the pollution with each other

Pollution 

Pollution means presence of anything in the system which is not naturally found in that or presence in unproportionate manner. It is the process of making the environment land water and air dirty by adding harmful substance to it which causes imbalance in the environment.
Environmental pollution is a serious problem of the industrialized societies. The industrial development & the green revolution have adversely affected the environment. Day by day pollution has been increasing & imbalance has threatened the very survival of all forms of life. It is threat to the whole world. People have converted the life supporting system of the entire living world into their own resources and have vastly disturbed the natural ecological balance. It is defined as the unfavourable alteration of our surroundings. In India allay the source of water lie rivers lakes ponds and wells have been polluted and are unfit for drinking. As a result of the increased use of fertilizers, the rivers seas and oceans have become contaminated with harmful pollutants. Pollution is a product of people activities which directly or indirectly  responsible for the changes in environment. All changes in the physical, chemical or biological characteristics of land, air, or water than harm human life and other living things. Population explosion, rapid industrialisation deforestation unplanned urbanization scientific and technological advancement. 
Pollution occurs in different forms like air, water, soil, radioactive, noise, heat, light. All forms of pollution have two sources of matter like point and non-point sources. The point sources are easy to find while the non-point sources are hard to find and hard to control. 

 TYPES OF POLLUTION 

Different types of pollutions occur and effect on people and the environment as a whole.

1) Air pollution

It refers to the contamination of atmospheric air due to presence of some substance and gases which have poisonous effect. Day by day the fresh air of our environment is getting polluted due to mixing of biological molecules and some other harmful material. Such polluted air is causing health problems.

2) Water pollution

Fresh water is the most important sources of life on the earth. Any living thing may survive without food for days however it is impossible to imagine life without water and oxygen. The ever-increasing human population enhances the demand of water for purpose like drinking, washing, performing industrial processes, irrigation crops, arranging swimming pools and others water-sports centre. Water pollution is done by the people of all over the world because of increasing demand and competition of luxuries life. 

3) Soil pollution

It occurs due to incorporation of unwanted chemicals in the soil due to human activities. Use of insecticides and pesticides absorbs the nitrogen compounds from the soil making it unfit for plants to drive nutrition from. Soil pollution refers to the mixing of human made chemicals like industrial wastes, agricultural chemicals, and other harmful disposal of wastes from houses, factories, etc. into the natural soil which causes land degradation and makes it unfit for the cropping.

4) Radioactive pollution

It is highly dangerous when it occurs. It can occur dur to nuclear plant malfunctions, improper nuclear waste disposal, accidents, etc. It can cause cancer, infertility, blindness, defects at the time of birth; can sterile soil and affect air and water. Radioactivity is radioactive decay or emission of particles (neuron, proton or heavier particles) from an atom or nucleus. Recently radioactive elements are also used in research and medicine. These pollutants are directly linked to nuclear energy.

5) Noise pollution

The unwanted sound that can have deleterious effects on human health and environmental quality. It is commonly generated inside many industrial facilities and some other workplaces, but it also comes from highway, railway, and airplane traffic and from outdoor construction activities. It has become a serious problem for human health. The noisy atmosphere in which we are living is an obstacle in securing good health. 

6) Thermal pollution

Thermal pollution is the degradation of water quality by any process that changes ambient water temperature. Thermal pollution is usually associated with increases of water temperature in a stream, lake or ocean due to the discharge of heated water from industrial processes, such as the generation of electricity. Increase in ambient water temperature also occur in streams where shading vegetation along the banks is removed or where sediments have made the water more turbid. It is due to excess heat in the environment creating unwanted changes over long time periods; due to huge number of industrial plants, deforestation and air pollution.

7) Light pollution    

It occurs due to prominent excess illumination of an area. It is largely visible in big cities, on bill boards, in sports or entertainment events at the night. In residential areas the lives of the inhabitants are greatly affected by this. It also affects the astronomical observations and activities by making the stars almost invisible. Bright lightning in the function, big cities, etc. causes light pollution. Light pollution is also known as photopollution, it is the presence of anthropogenic light in the night environment. Light pollution occurs at night and is obtrusive, inappropriate or excessive artificial light.

    1. If the situations are not controlled then it will be worst, but this is actually a threat to our environment similarly to us..... ....
