What is the cause and effect of depletion of the ozone layer?

A lack of sunlight during the winter months in the Antarctic is the main cause. A smaller hole occurs during the winter months in the Arctic. Once the sunlight returns to either region, the hole quickly disappears Long term global thinning is a different issue.

Some reports indicate that thinning can occur due to man made gases reacting with ozone. Because ozone is so rare and reactive, only small amounts of these gases are needed to vause problem with the amount of ozone in the atmosphere The largest know thinning of the ozone in our atmosphere occurred in 1858 due to heavy solar flares. The thinning repaired quickly.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
