Causes of pollution

• Industrialization: It is the important cause of pollution. Among other things, industrialization widespread use of fossil fuels (oil, gas & coal) which are now the main sources of pollution.

• Population growth: With population numbers literally exploding around the world, the demand for food and other goods goes up. This demand is met by expanded production and use of natural resources, which in turn leads to higher levels of pollution.

• Over use and miss use of pesticide: Hardly one half of the treated pesticide deposits itself on the treated surface the rest is disseminated to uncharged areas. This make the environment polluted. They remain in water, soil, air and mammal adipose tissues for a long time and may cause long lasting time.

• Globalization: Globalization has become an effective facilitator of environmental degradation. Developing countries usually have much looser laws. Developing countries usually have much looser laws on environmental protection. With this “benefit” as well as the population growth and easy availability of cheap labor, big industry prefers to move its facilities to such “pollution havens” rather than work in more regulated markets.
