Pollution is contamination by a chemical or other agent that renders part of the environment unfit for intended or desired use. These uses also and very importantly consist of all wildlife and ecological requirements to hold life in all its natural forms.
Pollution damages the Earth's land, water and air. It results in contamination of the earth's environment with materials that interfere with human health, the potential of life, and the natural functioning of ecosystems (living organisms and their corporal surroundings).
Pollution is commonly caused by human actions, but can also be the consequence of natural disasters. Pollution can also occur from disruption or damage to wastewater collection and treatment infrastructure due to severe natural events like hurricanes or flooding. Most types of pollution affect the immediate area surrounding the source, and cut as you move away from the source.
Pollution is often caused by the garbage that habitancy throw on the ground or into oceans, lakes or rivers.
Pollution exists in many forms and affects many distinct aspects of the Earth's environment. Some main types of pollution are:-
- Water pollution is a serious global question and the largest water pollution question is from sewage contaminating watercourses.
- Air pollution arising from many sources, and is bad in cities. Car transport emissions causes a lot of the air pollution we see. But did you know that air pollution also can exist inside homes and other buildings? Poor ventilation causes about half of the indoor air pollution problems. Air pollution contributes to the greenhouse effect.
- Highway vehicles, and shipping, are major contributor to air pollution worldwide.
- Photochemical air pollution is commonly referred to as 'smog'. Urban air pollution is often caused by a photochemical, and is commonly known as smog.
- Radioactive pollution results from inadequate nuclear safety.
- Light pollution, includes light trespass, over-illumination and grand interference.
- Noise is a form of pollution as well but is unlike the others as it is transient; once the pollution stops, the environment is free of it.
Recently, there has been a heightened interest in the intercontinental transport of pollution. European pollution has been tracked to Asia, as well as the Arctic.
Pollution operate involves higher production costs for the industries concerned, but failure to implement enough controls may consequent in irreversible environmental damage and an growth in the incidence of diseases such as cancer.
Pollution can be achieved by reducing or eliminating waste at the source by modifying production processes, promoting the use of non-toxic or less-toxic substances, implementing conservation techniques, and re-using materials rather than putting them into the waste stream. But even with these new laws air pollution is still on the growth allembracing throughout the world. This is especially so in the developing countries.
We should all do what we can to minimize pollution and become 'green'.
