What is Pollution?

Pollution is when something is added to the environment that is harmful or poisonous to living things. Smoke or dust in the air is a type of pollution as it is bad for the lungs when we breath in. Sewage in drinking water is another type of pollution, as it can make people ill because it contains germs and viruses. People living next to a building site where there is too much noise can become sick as they cannot sleep.

  1. Air Pollution:

    Air pollution occurs when the air contains pollutants such as gases, fumes and dust in harmful amounts. Air pollution can be harmful to the health of humans and animals if left unchecked.

  2. Water pollution :

    Water pollution is the contamination of water bodies This form of environmental degradation occurs when pollutants are directly or indirectly discharged into water bodies without adequate treatment to remove harmful compounds.
    example: lakes, rivers, oceans, aquifers and groundwater

  3. Noise pollution :

    Noise disturbance is the disturbing or excessive noise that may harm the activity or balance of human or animal life.Example: machines and transportation systems, motor vehicles, aircraft, and trains.

  4. Land pollution:

    Land pollution is the deterioration of the earth’s land surfaces, often directly or indirectly as a result of man’s activities and their misuse of land resources. Exploitation of minerals has also contributed to the destruction of the earth’s surface.

  5. Light pollution :

    Light pollution occurs due to prominent excess illumination of an area. It is largely visible in big cities, on advertising boards and billboards, in sports or entertainment events at the night.

  6. Thermal pollution:

    Thermal pollution is the degradation of water quality by any process that changes ambient water temperature. A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers.

  7. Visual pollution:

    Visual pollution is an aesthetic issue and refers to the impacts of pollution that impair one’s ability to enjoy a vista or view. Visual pollution disturbs the visual areas of people by creating negative changes in the natural environment.

    Effects of Pollution

    1. Environment Degradation :

      Environment is the first casualty for increase in pollution weather in air or water. The increase in the amount of CO2 in the atmosphere leads to smog which can restrict sunlight from reaching the earth.

    2. Infertile Land :

      Plants may not be able to grow properly. Various forms of chemicals produced from industrial waste is released into the flowing water which also affects the quality of soil.

    3. Global Warming :

      Environment is the first casualty for increase in pollution weather in air or water. The increase in the amount of CO2 in the atmosphere leads to smog which can restrict sunlight from reaching the earth.

    4. Weight

      The emission of greenhouse gases particularly CO2 is leading to global warming. Every other day new industries are being set up, new vehicles come on roads and trees are cut to make way for new homes.

    5. Human Health :

      The decrease in quality of air leads to several respiratory problems including asthma or lung cancer. Chest pain, congestion, throat inflammation, cardiovascular disease, respiratory disease are some of diseases that can be causes by air pollution.

    6. .Ozone Layer Depletion:

      Ozone layer is the thin shield high up in the sky that stops ultra violet rays from reaching the earth.

The air we breathe has a very exact chemical composition; 99 percent of it is made up of nitrogen, oxygen, water vapor and inert gases. Air pollution occurs when things that aren’t normally there are added to the air. A common type of air pollution happens when people release particles into the air from burning fuels. Finally, air pollution can take the form of greenhouse gases, such as carbon dioxide or sulfur dioxide, which are warming the planet through the greenhouse effect. According to the EPA, the greenhouse effect is when gases absorb the infrared radiation that is released from the Earth, preventing the heat from escaping.
