Air pollution

Air pollution
Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm to humans, other living organisms including our natural environment and the atmosphere.
Air pollution its often devastating effects. In the last 200 years had appeared several main inclinations which became the major forces behind the surge in levels of air pollution throughout the globe.
Industrialization is the first fundamental pollution cause. Among other things, industrialization major contaminant is the use of fossil fuels (oil, gas & coal).
Population growth is the second fundamental pollution cause. 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 its turn leads to higher levels of environmental pollution in general, and air pollution in particular.
Globalization is another major pollution cause. Globalization has become an effective facilitator of air pollution. 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.
