The day was established by the United Nations General Assembly in 1994, on the 15th anniversary of the signing of the Montreal Protocol on Substances that Deplete the Ozone Layer.<\/p>\n<p>The ozone layer is a region of Earth&#8217;s stratosphere that absorbs most of the Sun&#8217;s ultraviolet radiation. It contains high concentrations of ozone (O3) relative to other parts of the atmosphere, although still small in relation to other gases in the stratosphere. The ozone layer contains less than 10 parts per million of ozone, while the average ozone concentration in Earth&#8217;s atmosphere as a whole is about 0.3 parts per million.<\/p>\n<p>The ozone layer is important because it protects life on Earth from harmful ultraviolet radiation. Ultraviolet radiation can cause skin cancer, cataracts, and other health problems. It can also damage plants and animals.<\/p>\n<p>Ozone depletion is the thinning of the ozone layer in Earth&#8217;s stratosphere. The ozone layer absorbs most of the Sun&#8217;s ultraviolet radiation, which is harmful to life on Earth. Ozone depletion is caused by human activities, such as the release of chlorofluorocarbons (CFCs) into the atmosphere.
