No. CFCs from man are causing the hole in the ozone layer.
Ozone is a protective layer in the upper atmosphere. It is formed, when oxygen molecules absorb short wavelength ultra violet radiations from the sun. Ozone is mostly destroyed by free radicals in the atmosphere.
When compounds like CFCs (chlorofluorocarbons) and other halocarbons are released, they are dissociated by sunlight into chloride radicals. These radicals attack ozone, thereby decreasing its concentration. This results in a thinning of the ozone layer, and in polar regions, a hole.
The holes occur at the poles, and usually in Antarctica because of the extreme cold. During the winter polar stratospheric clouds form which are able to convert gases in the atmosphere into Cl (chlorine) and ClO (chlorine monoxide). When the sun arrives at the end of winter, that is the trigger to begin. This is why the hole is largest in spring.
Another view:
Unfortunately many people confuse the natural hole that we see annually in the ozone layer over the Antarctic, with the possibility of ozone depletion over the entire planet. CFC's, while not a significant factor are not a major factor in this annual event that has always occurred since the atmosphere first contained oxygen.
Looking at the complete picture we see the major reasons for the hole include:
1. Natural chemical reactions (this is why the hole is so much larger in the Antarctic then the dimple in the Arctic
2. Seasonal variations in sunlight. (Ozone is naturally decays into oxygen, so we need sunlight to create more ozone) This is why the hole only occurs during the long winter months
3. Special isolation issues associated with the Antarctic
4. ozone depleting chemicals from nature and man. (anything with chlorine. like salt water)
5. Volcanic aerosols and stratospheric clouds.
The lack of sunlight hitting the Antarctic causes this very natural event and is exacerbated by the other conditions. This is also why the ozone returns to normal within weeks of daylight returning to the area. We know that this hole has been happening for many years before the invention of CFC's by man. In fact, the largest single thinning of this layer happened with zero CFC's present. Solar discharges in 1859 caused the single largest thinning of the ozone layer. In just this one event, it managed to thin the layer by 5%.

What else can I help you with?
Does perfume makes the ozone layer thinner?
Perfume itself does not make the ozone layer thinner. However, some chemicals in perfume, such as volatile organic compounds (VOCs), can contribute to the formation of ozone-depleting substances when they react with other pollutants in the atmosphere. It is important to choose perfumes with fewer VOCs to minimize their impact on the ozone layer.
Do CFCs make the ozone layer thicker?
No, CFCs actually cause damage to the ozone layer by breaking down ozone molecules. This depletion results in a thinner ozone layer, which can lead to increased levels of harmful ultraviolet radiation reaching Earth's surface.
What gas can make ozone layer stronger stronger?
Only ozone can make itself stronger. It will make ozone layer thick.
What chemicals make up the ozone layer?
The ozone layer is made up of ozone molecules only. These molecules are reactive in nature.
Is there a ozone layer?
Ozone in troposphere is not created by UV. It is created by lightening.
What substances can make the ozone layer becomes thinner?
Chlorofluorocarbons (CFCs).

Describe The destruction of The ozone layer by CFCs?
The CFC's are present in the ozone layer. They make oxides with ozone and deplete it.
What can you do about it ozone layer?
Curb the CFC's. This will make ozone replenish.
What chemicals make up the ozone layer?
The ozone layer is made up of ozone molecules only. These molecules are reactive in nature.
What is up with the ozone layer?
Ozone layer depletion is going on as CFC gases which are pollutants are responsible for the depletion of ozone layer. CFC convert ozone to oxygen and make it useless for the absorption of UV radiation.
How could the Ozone layer be fixed?
The ozone layer can be fixed. It can be done when we plant trees to make the environment clean.
Is it possible to make an artificial ozone layer?
no its not
Which gases helps make the earth protection shield?
Ozone in the ozone layer.
How does ozone layer damage?
CFC gases are responsible for the depletion of ozone layer. CFC convert ozone to oxygen and make it useless for the absorption of UV radiation.
