Causes of Environmental Pollution
Pollution from cars, trucks, and other vehicles is and has been our major environmental pollution issue for almost a century now. The problem is we did not realize this until the problem had manifested to monumental proportions.
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 forests has 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.
