Briefly explain the causes of environmental pollution
Answers
Causes
The factors which contribute to environmental pollution exist in plenty. While air pollution is attributed to burning of fossil fuels, water pollution is associated with drainage of waste. Similarly, noise pollution is caused when the level of noise crosses certain decibels, and soil pollution or land pollution is caused as a result of contamination of soil due to the introduction of chemicals in the same. The use of chemical fertilizers and pesticides on agricultural land results in contamination of soil. These chemicals stay in the soil for a long time and eventually come in contact with our body through the food that we consume, which is grown in the polluted soil. While thermal pollution is attributed to its use as coolant by power plants and industries, radiation pollution is attributed to accidents involving radioactive substances as a result of human error.
That, however, is just a brief explanation, and each of these causes of pollution are attributed to numerous human activities. For instance, air pollution is caused when various harmful gases are released in the atmosphere from industrial plants and automobiles. The concept of water pollution includes the pollution of freshwater sources as well as oceans. On one hand, freshwater sources are being converted to dumping grounds as a result of industrial water pollution, and on the other, oceans are bearing the brunt of oil spills and marine transportation. The rate at which waste is being dumped is these sources of water is quite threatening in itself, and the same contaminated water is used by a large part of the population.
*Pollution from cars, trucks, and other vehicles is and has been our major environmental pollution issue for almost a century now.
*Fossil fuel emissions from power plants which burn coal as fuel contributed heavily, along with vehicles burning fossil fuels, to the production of smog. Smog is the result of fossil fuel combustion combined with sunlight and heat. The result is a toxic gas which now surrounds our once pristine planet. This is known as “ozone smog” and means we have more problems down here than we do in the sky.
*Carbon dioxide is another product from all of the vehicles on the planet as well as unreformed power plants and other industrial facilities. A continually growing population of humans and clear cutting of forestshas exacerbated this problem so natural defenses are no longer present and carbon dioxide levels are on the rise.
*Water pollution is a major issue. Many industries dump wastes into rivers, lakes, ponds, and streams in an attempt to hide wastes from EPA inspectors. These water sources feed major crops and food becomes contaminated with a variety of chemicals and bacteria, causing rampant health problems.
*Radiation comes into play as well. This is an exceedingly nasty pollution issue and requires extensive description. Primarily, there is radiation from the sun. As the natural ozone layer around the Earth has become depleted. The sun is wonderful, but the only reason we are able to survive on this planet so close to the sun is due to the fact of natural shielding against solar radiation. As the protective ozone layer around the planet has become thinner, ultraviolet radiation has risen significantly, causing increases in skin cancers and other types of cancer in all countries, killing millions of people every year.
*More radiation is a problem. The sun shining brightly on a naked planet is not the only source of radiation we are exposed to. Electromagnetic radiation is another insidious culprit. Once upon a time, the major concern around this type of radiation was due to high tension wires which carry huge amounts of electricity to cities. Now, we even carry sources of this radiation with us as cell phones, laptops, tablets and other wireless devices.
