This exact question has been asked a hundred different ways:
Humans are causing ozone depletion by using CFC's. These CFC's react with ozone to deplete it.
We need to reduce ozone depletion. We can do that by curbing the use of CFC's.
To reduce ozone depletion, we must stop the use of CFC's. They react with ozone to deplete it.
To reduce the depletion, curb CFC's. they react and deplete ozone.
The ozone depletion depends upon the usage of ODS by humans. If these ozone depleting substances are reduced then the ozone depletion will slow down.
The effects of ozone depletion of humans are:skin cancerEye cataractSuppression of immune system.
The ozone depletion on humans and plants have a huge impact. UV falls over them and kills them.
Th main cause of ozone depletion is the use of ozone depleting substances by the humans. These chemicals react with ozone to deplete it.
In order to reduce the ozone layer depletion we can minimize the use of products containing CFC's. These are deodorants, spray cans, refrigerators etc.
The ozone depletion can be reduced by eliminating the root cause. The root cause is the use of CFC's.
See "What can we do to protect the ozone layer?"
The ozone depletion is caused by natural or man made processes. Man made process is the releasse of CFC's by humans.
