Sources of Environmental Pollution
Published by Rubbish is produced daily by human. Rubbish such as domestic wastes (leftover food) is classified as biodegradable while glass, plastic and metals are classified as non-biodegradable. Non-biodegradable rubbish is imperishable and remains in rubbish dump sites for a long time. Problems associated with the improper disposal of rubbish are foul-smelling dump sites, as well as the dump sites becoming a breeding place for microorganisms which cause diseases.

Pollution is defined as any undesirable change of the natural environment (physical, chemical or biological) caused by the release of harmful substances due to human activities. Pollution is any harmful substances (in the form of solid, liquid or gas) that have harmful effects on the environment. The increase in human population, the industrialization of cities and urbanization all contribute to pollution.

There are four categories of pollution: a) air pollution b) water pollution c) noise pollution d) thermal pollution. The various sources of environmental pollution are: a) combustion of fossil fuels b) disposal of by-products, wastes, toxic, substances, radioactive substances, smoke and eat from factories c) excessive use of chemical fertilizers, pesticides and fungicides in agriculture d) emission of noise, smoke and poisonous gases from vehicles and machinery e) disposal of rubbish such as plastics leftover food and solid substances f) disposal of sewage g) use of chlorofluorocarbon chemicals (CFCs).
Combustion of Fossil Fuels
Image via Wikipedia
Fossil fuels are produced from the remains of animals and plants which have been buried in the ground for hundreds of years. Fossil fuels such as coal, petroleum and natural gas are widely used in factories and vehicles to produce energy. The incomplete burning of fossil fuels releases carbon dioxide, carbon monoxide, sulphur dioxide, oxides of nitrogen and carbon particles into the atmosphere. Sulphur dioxide and oxides of nitrogen dissolve in rainwater to produce acid rain which is harmful to the physical and biological environment. The other gases and carbon particles cause air pollution.

Ghaz, you have combined a great narration with great pictures. In future, I’d like to take your help in getting pictures, if you don’t mind sharing your secrets. I especially like the photo that depicts the over fertilized land: it has the appropriate burnt-out links.

Well written narrative. A great eye opener for all self conscious pollutants in the planet. Humankind.

A very informative, and well written article Mr. Ghaz. We have made a lot of strides over the last decade in pollution of our land, and still have a long way to go. I must correct you on one picture in your article though. The tractor pulling the trailor is not spraying pesticides, but instead is spreading cow manure to naturally fertilize the land.

This is very important information. It’s good to have the basics put in again. Most of us recycle and upcycle. It’s good to be reminded of why.
