The Ozone layer is depleting due to man made chemicals we use everyday; this depletion causes an increase in the risk of someone developing skin cancer, and is potentially life-threatening. The ozone layer is a gas that protects the earth from the dangerous UV rays emitted from the sun. (Freedman, page 2934) Due to man made chemicals, the ozone layer is depleting which causes many problems for sustainable life on earth. The rays entering the earth’s stratosphere without the ozone layer will cause damage to many things, such as someone’s eyes or immune system, aquatic life, or plants. Another one of the consequences of ozone layer depletion is that it will cause an increase in the risk of developing skin cancer.
As scientific research is increasingly being conducted. Very movie like weapons are being created such as rocket launchers, without caring about the fact that it destroys the ozone layer. Although it’s not as harmful to the ozone as CFCs, it still causes damage. Overtime they will become a huge problem for the ozone. They banned CFCs but not nitrous oxide in the Montreal protocol.
Our Radiant Planet: Depletion of the Ozone Layer Ozone is a relatively unstable form of molecular oxygen containing three oxygen atoms produced when upper-atmosphere oxygen molecules are split by ultra violet light. Stratospheric ozone is found in a broad band, extending generally from 15 to 35km above the earth. Although the ozone layer is surprisingly thin, it acts as a protective shield to the earth, as it filters out most of the harmful solar ultraviolet radiation (in particular UV-B) that would otherwise reach our planets surface. Humans have damaged the ozone layer by adding molecules containing chlorine and/or bromine that lead to ozone destruction. The largest group among these are chloroflurocarbons (CFC's).
Human activity has been the prime cause of the depletion and thus can be eradicated through human activities in order to conserve it to sustain life. The use of CFC’s have otherwise known as Ozone Depletion Substances have caused patches/ holes in the ozone layer, which protects life from direct ultra-violet rays. The exposure to these rays make humans prone to cancer and other fatal diseases and soon the earth will not be able to sustain life. To curb or totally eradicate this, countries have come together to raise awareness, provide funds and support movements to eliminate Ozone Depletion Substances to make life on earth sustainable to live on and for future generations to come.
When CFC's remain in their original molecule form they are harmless (CQ Researcher 303). When ultraviolet rays come in contact with the CFC, it breaks down the molecule part. The CFC cell attaches to the ozone layer and begins multiplying and braking down the ozone layer. Ozone destroying chemicals are extremely stable, so they last in the atmosphere for many decades. That means that if production of CFC's and halons stopped today, the chemicals already released into the atmosphere would go on destroying ozone well into the 21st century.
The ozone layer is situated in the stratospheric layer of the atmosphere. It is important to the on-going stability of life on Earth as it prevents harmful UV-B radiation from reaching the troposphere (i.e. the layer of atmosphere that we live in). Were this radiation to reach us in large quantities, it could mutate the DNA in our cells and have fatal results. It is thanks to the ozone layer that this doesn’t happen, but a hole has formed in the ozone layer over Antarctica which could affect us severely.
But it can also be bad of the ozone was too low to the earth’s surface it can pollute the air and kill or put people in critical condition. If it shrinks too much, which probably could happen, it would no longer keep us safe form the sun. Many scientist are concerned for the ozone layer, and they are worried that is shrinking too much. They figured out most of it is caused by the chemicals that we humans create. In 1970 scientist saw how much is shrinking and found that chlorofluorocarbons or (CFCs) are hurting the ozone, the CFCs are like the hairsprays, deodorants, and coolers that worked in the refrigerators, and air conditioners are all hurting the ozone layer.
There is a layer of chemicals twenty kilometers up in the stratosphere called the ozone layer. This layer protects the inhabitants of earth by reflecting much of the suns harmful ultra violet (UV) rays. Without this layer above us, many living things including humans could not survive. The ozone layer is currently depleting and the reason for this is believed to be caused by a few things. Deforestation, fertilizer use and fuel combustion are minor contributors to this problem while chemicals such as chloroflourocarbons (CFCs), halons, carbon tetrachloride, methyl chloroform, methyl bromide and hydrochloroflourocarbons (HCFCs) are the major contributors to the deterioration of the ozone layer.
