Noise Pollution

Noise pollution is any loud sounds that are either harmful or annoying to humans and animals. Examples  of noise pollution are:

  • Airplanes, helicopters and motor vehicles.
  • Construction  or demolishment noise.
  • Human activities such as sporting events or concerts.


Noise  pollution can be disruptive to human stress levels, may be harmful to the unborn babies, and drives animals away  by causing nervousness and decreasing their ability to hear prey or predators.


Thermal Pollution

Thermal pollution is caused by an increase in temperature caused by human activity.

Warmer lake water from nearby manufacturing (using cool water to cool the plant and then pump it back into the lake).

The rise in temperatures in areas with lots of concrete or vehicles, generally in cities.


This type of pollution can cause aquatic life to suffer and die due to increased temperature can cause discomfort to the communities, and will affect the plant life in and around the areas.


Visual  Pollution

Visual pollution is what you call anything unattractive or visually damaging to the nearby landscape.

  • Skyscrapers that blocks a natural view.
  • Carving on trees, rocks or other landscapes.
  • Billboards, litter, abandoned homes and junkyards cause pollution.


Visual pollution destroys the natural beauty of nature.


Water Pollution

  • Raw sewage running into lakes or streams.
  • Industrial  wastes spill contaminating  ground water.
  • Dumping of items or substances into water bodies.
  • Biological contamination such as bacteria growth.
  • Farm runoffs into nearby bodies of water.


Water pollution is dangerous to human mankind as a whole.
