- The major natural sources of light are the luminous sun and stars and the non-luminous moon. These bodies give light during the day and at night.
- As part of technological advancement, humans have created electricity. The presence of uninterrupted electricity has become a yardstick used in measuring the level of development of an area.
- Most people can’t imagine living without the modern convenience of electric lights. In big cities, it is almost impossible to see the stars and galaxies.
- Light pollution is the presence of excessive artificial lights, such that they result in the brightening of the skies at night.
- The negative effect of light pollution areas follows:
- Indoor light pollution cause glare effect.
- It can cause an inability to sleep.
- Outdoor light pollution confuses nocturnal organisms.
- Outdoor light pollution leads to unnatural occurrences such as birds singing at odd hours.
- Light pollution alters plant flowering and development patterns.
- Light pollution, called sky glow, also makes it difficult for astronomers, both professional and amateur, to properly see the stars.
- According to a study by the American Geophysical Union, light pollution could also be making smog worse by destroying nitrate radicals that helps the dispersion of smog.
Radioactive/Nuclear Pollution - An example of radioactive pollution is the Fukushima Daiichi nuclear disaster of 2011 and the Chernobyl disaster of 1986 Attempt to generate electricity through the fission of radioactive materials, uranium, and plutonium led to nuclear power plant accidents, which resulted in the release of toxic chemicals and radiation into the environment
- Radioactive pollution is the release of harmful radioactive materials into the environment.
- Sources of radioactive pollution can be natural or man-made. This emission can come from nuclear power plants, cosmic rays earth crust, nuclear tests, mining, nuclear weapons, hospitals, accidental spill of radioactive chemicals, factories or radioactive wastes.
- Nuclear tests are the main human cause of radioactive pollution. Natural emissions usually have low energy levels and are not harmful. Human activities like mining bring radioactive materials beneath the earth to the surface.
