Question: Will the earth's ozen layer desire in 2017

The ozone layer has been thinning and it has even ripped in a few places, forming holes. This is mainly due to the pollution that we pump into the atmosphere. However, steps have been taken to reduce pollution and we are seeing these ozone holes slowly start to ‘heal’ – so hopefully everything will be OK!
