Complete deterioration is not required for Nature to rid Herself of Mankind. We can't put sunscreen on all the plants on the land and in the sea...

It was nonexistent before there was significant oxygen in the atmosphere. After the Great Oxidation Event, we developed our ozone layer, complete with annual ozone "holes" at each pole. We have evidence of sporadic events punching holes in the ozone layer from time-to-time. Since the 1700s, the ozone layer has been getting steadily thinner. This gets us to "current events".
If CFC's cannot be used the ozone level will grow again in the next 60 - 120 years
No, HAARP (High-Frequency Active Auroral Research Program) is not responsible for the holes in the ozone layer. The depletion of the ozone layer is primarily caused by human activities releasing chemicals like chlorofluorocarbons (CFCs) into the atmosphere. These chemicals break down ozone molecules, leading to thinning of the ozone layer.
The ozone layer only formed about 600 million years ago when there was already a diverse array of life on Earth. Dinosaurs went extinct around 65 million years ago due to a combination of factors, such as a large asteroid impact and volcanic activity, rather than a lack of protection from the ozone layer.
Predicting the exact state of the ozone layer in ten years is difficult due to various factors such as human activity and climate change. Efforts to reduce harmful substances like chlorofluorocarbons have led to gradual healing of the ozone layer, but uncertainties remain. Continued monitoring and international cooperation are crucial to preserving and restoring the ozone layer in the future.
The ozone layer after 5 years is dependent on us. It depends how we use CFC's.
Ozone layer was depleted. It's size has been coming to normal in recent years.

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.
The ozone layer has been decreased over the years. It is because of use of CFC's.
If CFC's cannot be used the ozone level will grow again in the next 60 - 120 years
Because the ozone layer provides a thin layer of protection from the harmful UV rays or ultraviolet rays.
There have been hundreds of ozone layer slogans in the past several years. There are many groups who are concerned about damage to the ozone layer and their campaigns and strikes have brought the problem to the attention of many other people.
In the atmosphere. Hundreds of millions of years ago.
