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 that 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 that 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 an 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.

EFFECTS OF ENVIRONMENTAL POLLUTION:

  • The polluting gases mentioned above have an interesting effect on the climate. Essentially, these gases form a veil around the planet which holds heat in, increasing the overall temperature of the planet. The rise in planetary temperature, or global warming, is not immediately noticeable. However, even a rise of a few degrees Centigrade causes catastrophic changes in weather. This is happening now.
  • Pollen has increased. It is ironic, but even with fewer trees in the world; the increase of carbon dioxide emissions induces plants such as ragweed and many trees to produce more pollen than ever before. This has resulted in rampant allergies across the world, affecting the health of billions of people.
  • One of the solutions to tamp out carbon monoxide emissions from coal-burning power plants was and still is to use radioactive power plants. While this does cut down on gas emissions significantly, there is radioactive waste that causes various cancers to bloom in major cities and small towns all around while destroying ecosystems entirely.
  • Global temperature has risen significantly over the years. The protective atmosphere is further being polluted by methane gas released from melting icecaps. This is causing rampant weather issues around the planet.

This all seems like a fairly bleak outlook for the planet and all the creatures on it. It is, in fact, a load of dark and very real truth. For much of it, there is little turning back. Being realistic, though solutions are in the works to combat global warming, the hope is dim. Radiation does not go away quickly either, especially in a technological age requiring more power, more gas, and intensified depletion of protective gases around the planet. We are on a significant downhill snowball ride to hell. There are things we can do. Let us take a look at some of the solutions which are currently being implemented to reduce pollution.
