Ozone Layer
The ozone layer is a vast substance that keeps us alive.The ozone layer protects us from the suns harmful ultra violet rays. It is found in two places, the stratosphere and troposphere. In the stratosphere the ozone protects us from the suns harmful ultra violet rays that cause eye and skin damage. We call this type of ozone good ozone. The troposphere houses bad ozone. This type of ozone ruins crops, weaken our immune system and causes cancer. This type of ozone also causes urban smog.
The holes in the ozone layer are caused by burning fossil fuels and CO2 being emitted into the atmosphere. The ozone holes grow bigger in the winter and smaller in the summer. By 2072 scientist estimate the ozone layer to be fully repaired.
