Depletion of the Ozone Layer

... Now take into consideration that Australia is also directly beneath one of the largest ozone holes this planet has seen. ... 2
As skin cancer rates across the globe increase, many seem to ignore the fact that this disease is directly related to the destruction of the ozone layer and it’s inability to block out harmful ultraviolet light. Stratospheric ozone depletion over the past twenty years has resulted in a major increase in ultraviolet levels. Skin cancer is proving itself to be a major threat to our society and its future is based solely on the ability of the entire population to protect the ozone layer.
The “ozone layer” refers to the ozone within the stratosphere, where over 90 percent of the earth’s ozone is found. Ozone is an irritating, corrosive, colorless gas with a smell similar to that of burning electrical wiring. The ozone layer absorbs 97-99 percent of the sun’s high frequency ultraviolet light, which is potentially damaging to life on earth. 3
Ozone acts as our planet’s natural sunblock by deflecting the sun’s deadly ultraviolet rays. In the stratosphere, small amounts of ozone are constantly being made by the reaction between sunlight and oxygen. At the same time, ozone is being broken down by natural process. The total amount of ozone usually stays constant because its formation and destruction occur at about the same rate.
