This answer is the same as for a half dozen more ways to ask this exact question.
The loss of ozone is a great damage. It is a blanket to the layer of earth.
We have stopped the production of certain chemicals that damage the ozone layer.
The hole in the ozone layer is a natural occurance. It increases the risk of nothing. That the hole gets bigger is a symptom of depletion of the ozone layer in general. Depletion increases the risk of skin cancer, cataracts, mutation, crop loss, and loss of arable land.
Ozone layer depletion is an example of a positive feedback loop, where the thinning of the ozone layer allows more harmful UV radiation to reach the Earth's surface, leading to further ozone depletion.
Ozone layer has many holes in it. However it has a considerable major hole in it above Antartica continent. It is formed due to CFC gas. Beacuse of the hole there is an increase in the temperature of earth.
The loss of ozone layer is the loss of ozone molecules. It is due to the CFC gases released.
CFC's are causing loss of ozone layer. They react with ozone to deplete it.
Holes in ozone layer are the thinning of ozone layer. They cause loss of life of flora and fauna.
The loss of ozone is a great damage. It is a blanket to the layer of earth.
We have stopped the production of certain chemicals that damage the ozone layer.
See "What are the causes and effects of ozone layer depletion?"
The size of the ozone layer has changed. Due to the CFC's the ozone has decreased. Most of the loss has been over the poles.
Some scientists are concerned about ozone loss. It is because it will allows fatal UV rays to pass through.
The loss is global. there have been losses all over the globe.
The hole in the ozone layer is a natural occurance. It increases the risk of nothing. That the hole gets bigger is a symptom of depletion of the ozone layer in general. Depletion increases the risk of skin cancer, cataracts, mutation, crop loss, and loss of arable land.
Provision to reduce CFCs & CO2 emission
Ozone layer depletion is an example of a positive feedback loop, where the thinning of the ozone layer allows more harmful UV radiation to reach the Earth's surface, leading to further ozone depletion.
