According to the dictionary, air pollution is defined as the contamination of the atmosphere. Air pollution can be in the form of small particles, such as dust, or excessive gasses. Carbon dioxide, a greenhouse gas, is one of the main pollutant that is causing global warming. Fumes from vehicles, radiation from nuclear accidents, and the burning of fossil fuels all contaminate the air. These are linked to respiratory illnesses, such as asthma and some types of allergy.
Water pollution is when anything degrades or contaminates water's purity and quality. It can occur in any body of water, such as oceans, rivers, lakes, streams, and reservoirs. Examples of water pollution are dumping waste into the middle of the ocean, bacteria growth, raw sewage running into streams, and even oil spillage.
Land pollution is caused by misusing earth's resources and disposing waste inappropriately. Litter disposed on the side of the road and not in the rubbish bin is a common example of land pollution. This makes the sanitation workers's job harder. Pesticides and other farming chemicals are also examples of land pollution. We must avoid using them as best as we can. Not only has land pollution affected the lives of humans, but it has also done damage towards the natural habitats of animals.
Light pollution may sound rather silly, but it is caused by the over illumination of areas that are oftentimes not needed and will cause disruption. Some examples would include unnecessary lights (like at home when you're gone), night time sporting events or other forms of entertainment, and street lamps that emit light in many directions, not only downwards onto the street.
Thermal pollution is excessive heat caused by human activity that will cause lasting negative impacts on the earth over long periods of time. Thermal pollution can be caused by power plants, heat from factories, and deforestation. This kind of pollution can cause wildlife populations to have a difficult time adjusting to the temperature changes.
Noise pollution are loud noises that cause disruption or annoyance to humans and animals. Examples of noise pollution includes vehicles of airplanes, loud constructing noise, traffic, and even concerts. Constant exposure to noise pollution can cause hearing damage and wildlife disturbances.
Visual pollution is basically unattractive views or things that visually damage the nearby landscape. It can range from skyscrapers that block the view of the scenery behind to billboards/advertising to even graffiti on nature. All these can cause eyesores.Radioactive pollution is considered rare. But when it occurs, it is very deadly. It can cause intense damage to human health. Uranium mining operations and nuclear power plant leakage are sources of radioactive pollution. The unfortunate event of Japan's nuclear leak a few years ago would classify as radioactive pollution. The explosion of the atomic bombs on Japan are also examples of radioactive pollution. Radioactive pollution can cause cancer, loss of white blood cell, and vomiting.
Personal pollution is the contamination of a person's health and well-being. It may even contribute to the other 8 forms of pollution. Smoking and drugs are common examples of personal pollution. Smoking can cause lung cancer, while drugs can cause premature aging.
Air pollution in Hong Kong is a serious problem. Cases of asthma and bronchial infections have increased over the past few years because of bad air quality. Traffic is a main cause in Hong Kong's air pollution. To find out more, visit this site http://www.airqualitynow.eu/city_info/prague/page4.php
It is important to not contribute to any of these forms of pollution, as they will, sooner or later, affect the you and the environment you live in. Numbers 35:33-34 says: "You shall not pollute the land in which you live...you shall not defile the land in which you live, in the midst of which I dwell, for I the Lord dwells in the midst of the people of Israel." As stewards of God's creation, we must be take care of the land, as God commanded.
