Essays Conclusion Ozone

Chlorine then reacts as a catalyst to break down ozone molecules into oxygen, reducing the ozone concentration.The more CFCs used, the greater the destruction of the ozone layer, according to the theory.

A NASA satellite photo revealed that a portion of the ozone layer the size of the continental United States had disappeared from the atmosphere above Antarctica.

This startling information confirmed the theory of scientists that the use of CFCs were rapidly destroying the ozone layer.

Guest essay by Steve Goreham Another year has passed and that stubborn Ozone Hole over Antarctica refuses to go away. Sherwood Roland of the University of California published a paper asserting that chlorofluorocarbon (CFC) pollution from industry was destroying the ozone layer in Earth’s stratosphere.

Data from the National Aeronautics and Space Administration (NASA) shows that the Ozone Hole for the fall maximum season grew 22 percent from 2014 to 2015. CFCs were gases used in hair spray, refrigerators, and insulating foams.

If a global effort is not made to end the unnecessary use of CFCs, the inhabitants of this planet face an extremely difficult and frightening future. They were the product of an intensive search by engineers with the G. Research Corporation to find a safe, non-toxic, non-flammable refrigerant. “From eight aerosol-related companies in the late forties, the industry grew to more than one hundred just a few years later” (Cagin and Dray 87).

Frigidaire patented the formula for CFCs in 1928 and the “new wonder gas” was named Freon. [with the] combination of safety, cleanliness, and efficiency . CFCs were soon making the lives of millions of Americans much more comfortable.According to Gordon Keyes with the National Institute of Atmosphere and Water, depletion of this thin layer of ozone not only increases health risks such as skin cancer and suppression of the immune system, it may also cause a decrease in aquatic species and endanger the basic food chain of the ocean (3).The chlorine which results from the breakdown of CFCs in the atmosphere combines with other “greenhouse gases” and enhances the global warming threat.Scientists were concerned that degradation of the ozone layer would increase rates of skin cancer and cataracts and cause immune system problems in humans.Former Vice President Al Gore’s 1992 book claimed that hunters reported finding blind rabbits in Patagonia and that fishermen were catching blind fish due to human destruction of the ozone layer, but this has not been confirmed.Since 1986, world consumption of Ozone Depleting Substances (ODS) is down more than 99 percent, effectively reaching zero by 2010.The Montreal Protocol has been hailed as an international success in resolving a major environmental issue.Seth Cagin and Phillip Dray, co-authors of Between Earth and Sky, inform us in their story of CFCs that “Freon soon topped the list of wonders, a ‘miracle’ refrigerant . They were also making the Kinetic Chemical Company, a joint corporation of General Motors and Dupont who manufactured and marketed Freon, extremely wealthy.But in August of 1985, the entire world was informed by a group of scientists at NASA’s Goddard Space Flight Center that the sky was literally falling.Mankind’s very existence is totally dependent on this fragile ecosystem’s ability to maintain itself.A valuable player in the balance of the environment, the ozone layer, is facing a very serious threat by man.
