What Caused the Hole in the Ozone Layer?

Answer

Holes in the ozone layer are caused by the increasing concentrations of ozone-depleting chemicals in the stratosphere. These chemicals come from spray cans and refrigerants and they include chemical compounds with chlorine and/or fluorine attached to carbon otherwise known as CFCs.

The hole in the Ozone layer is mainly broken down by ChloroFluoroCarbons CFC's and by nitrogen oxides chemicals. They are very important chemicals but once they are released into the atmosphere they are a serious pollutant. A small amount of CFC destroys a lot of ozone.
Global warming has been considered to be the reason behind the supposed hole in the ozone layer as carbon emissions bond with the tri-oxygen and release carbon dioxide and carbon monoxide leaving humans with no chance for life in the future. Ancient theories point to the polar natures of the earth creating a hole for the north and south poles to be visible and accessible.
