Ozone Depletion
Discovered in 1973 by Rowland and Molina.
Ozone depletion is not just an issue concerning Canada. Ozone depletion is seen very clearly in the Artic where the ozone becomes extremely thin due to harmful chemicals in our atmosphere that cause it to deplete. The main chemical that causes this depletion is CFC’s or chlorofluorocarbons. These CFC’s come from air conditioners, refrigerators and some aerosols. Heavily populated suburban cities contribute the most to ozone depletion due to their usage of refrigerators and ACs. While smaller and less wealthy cities have a lower contribution towards the ozone depletion. Other than Canada, many wealthy or developed countries are the main source of CFC’s and contribute the most towards ozone depletion. (Such as the USA, England, France and Australia)
The public is not being made aware of this problem as much as scientist would like. Many know of the problem and are concerned but do not know how to stop of contribute to the reduction of the cause. There are many documentaries and ads about reducing a home’s AC usage to save on energy but there aren’t very many speaking out on the ozone depletion. The best way people become aware of this problem is when the issue of global warming is brought up. The ozone’s depletion does cause UV rays to enter into the earth’s atmosphere much easily and thus cause the temperature to increase.

Thing I can do to prevent the ozone depletion is by cutting down the amount of AC I use, not using any type of aerosols and keeping not more than one refrigerator at my house. I could also educate people on what contains CFC’s and other chemicals that harm the ozone and how to cut down or replace such products with environmentally friendly products. Luckily for Canadians, many products that contain CFC’s are now not available to the public. The government created a ban on them on June 1975.Ozone depletion is an international problem. Countries such as Canada, the US, Russia and more have come together and help prevent the increase in the hole.
