(KTVI) – The hole in the ozone layer is the second smallest its been in the last 20 years according to an  October 2012 report released  by Life Science.

The ozone layer is responsible for preventing ultraviolet light from reaching the Earth’s surface. Protection from high exposure of UV light is vital in fending off sun burn and skin cancer.

This current decrease of the hole in the Earth’s ozone layer bids well for Antarctica according to AccuWeather. The continents’ high winds cause a vortex of cold air to circulate over the continent making the region more susceptible to the radiation exposure.

The hole is caused by human-produced chlorofluorocarbons (CFCs), which have been phased out in use on an international level over the last three decades. CFCs were commonly found in aerosols and refrigeration products until the Montreal Protocol was adopted in 1987.
