Ozone Layer Depletion and its Contribution to Climate Change

Satisfactory Essays
Starting from the industrial revolution, our skill to revolutionize the world around us has become intense. Before, the impact on our planet was almost unnoticeable. Recently, the effects of our increased activity have created a noticeable impact to the world. We have thinned the ozone layer and may now be starting to change the very climate system upon which we and all other life on Earth depend on. It’s like we are experimenting with the future, but unlike lab experiments, we can scrap it and start a new one is it fails, but altering the climate cannot be easily undone. We will be forced to live with the consequences for a very long time. Undoing what we have done to the ozone layer is not that simple. What is the ozone layer? The ozone layer is a part of the stratosphere containing highly poisonous O3 gas with a strong odor. Ozone is formed by the action of solar ultraviolet light on oxygen. Ozone at ground level is a health hazard. High concentrations of ozone at ground level are dangerous to breathe and can damage the lungs. However, the ozone layer inhibits most ultraviolet and other high energy radiation from entering to the earth's surface. The ozone has been thinning since the 70s, but there was no hard proof that it was. In the mid 80's, scientists have discovered that a "hole" formed in the ozone layer, in an area where the ozone was up to 50 percent thinner than normal and it develops occasionally in the ozone layer above Antarctica. The hole in Earth's ozone layer keeps on getting bigger and bigger. Besides, the ozone layer is predictable to continue thinning well into the next century. Ozone layer protects the planet from dangerous ultraviolet solar rays, without the ozone layer, life will not be able to survi... ... middle of paper ... ...problem still exists. What is the government doing to help? 194 nations, including Canada, have signed an international agreement to end the production of chlorofluorocarbons (CFCs), halons and other ozone depleting substances (ODS). The agreement is called the Montreal Protocol on Substances that Deplete the Ozone Layer (1987). Many scientists are hoping that the ozone hole will be completely repaired by 2050, just by not using those chemicals anymore. Finally, while we can't fully stop the creation of ozone, we can defiantly help reduce it. To prevent Ozone depletion, we can start by using energy efficient appliances. Recycling and reusing of materials can also help in preserving the zone. As well as getting governments to ban the use of chlorofluorocarbons in industries. Stopping the use of CFCs is the most important step towards a safe environment in future.
