Environmental pollution refers to the introduction of harmful pollutants into the environment. These pollutants contaminates the environment. It has a hazardous effect on the natural world and on the activities of living beings.
The major types of environmental pollution are air pollution, water pollution, noise pollution, thermal pollution, soil pollution and light pollution.
Deforestation and hazardous gaseous emissions also leads to environmental pollution. During the last 10 years, the world has witnessed severe rise in environmental pollution.
We all live on planet earth, which is the only planet known to have an environment, where air and water are two basic things that sustain life. Without air and water the earth would be like the other planets – no man, no animals, no plants. The biosphere in which living beings have their sustenance has oxygen, nitrogen, carbon dioxide, argon and water vapor. All these are well balanced to ensure and help a healthy growth of life in the animal world. This balance does not only help the life-cycles of animals and plants, but it also creates the perennial sources of minerals and energies without which the human civilization of to-day could not be built. It is for this balance that the human life and other forms of existence have flourished on earth for so many thousands of years.

But man, as the most intelligent animal, never stopped being inquisitive, nor was he content with the bounties of nature. His quest for knowledge and search for security succeeded in exploring newer and wider avenues of mysteries that remained baffling so long. Man’s excursions into the darkest regions of mysteries laid foundations for the stupendous civilization, for the conquests of men had ensured their domination in their world and gave them a key to control all the forces in nature.
With the dawn of the age of science and technology, there has been huge growth and development of human potentials. And, it is here that man first began losing control and became prisoner of his own creations.

Sources and Causes
The sources and causes of environmental pollution includes the following:
Industrial activities: The industries all over the world that brought prosperity and affluence, made inroads in the biosphere and disturbed the ecological balances. The pall of smoke, the swirling gases, industrial effluents and the fall-out of scientific experiments became constant health hazards, polluting and contaminating both air and water. The improper disposal of industrial wastes are the sources of soil and water pollution. Chemical waste resulting from industry can pollute lakes, rivers and seas and soil too as well as releasing fumes.
Dumping solid waste: Household and commercial waste pollutes the environment when not disposed of properly.
Vehicles: The smoke emitted by vehicles using petrol and diesel and the cooking coal also pollutes the environment. The multiplication of vehicles, emitting black smoke that, being free and unfettered, spreads out and mixes with the air we breathe. The harmful smoke of these vehicles causes air pollution. Further, the sounds produced by these vehicles produces causes noise-pollution.
Rapid urbanization and industrialization: The urbanization and the rapid growth of industrialization are causing through environmental pollution the greatest harm to the plant life, which in turn causing harm to the animal kingdom and the human lives.
Population overgrowth: Due to the increase in population, particularly in developing countries, there has been surge in demand for basic food, occupation and shelter. The world has witnessed massive deforestation to expand absorb the growing population and their demands.
Combustion of fossil fuels: The combustion of fossil fuels pollutes the air, the soil and the water with noxious gases such as CO2 and CO.
Agricultural waste: Fertilizers and pesticides used in agriculture are key causes of environmental pollution.
