The ozone layer is to protect our planet from ultraviolet radiation, which is covering between 9 and 22 miles above our planet Earth.
Scientists see the ozone hole in the Southern Hemisphere is caused by chemicals like chlorine and bromine migrating into the stratosphere, which is creating catalytic reactions during Antarctic winter.
Scientists from the European Union’s Copernicus Atmosphere Monitoring Service said that the hole in the ozone that forms every year over the South Pole is now larger than Antarctica.
The chlorofluorocarbons is the main cause of depletion of the ozone layer. The chemicals were first regulated & signed in 1987 by the Montreal Protocol. The Environmental Protection Agency expected it to be phased out by 2030.
