If the thinning continues, UV will enter the earth. There will be no life left.
You would find the thinning of ozone layer near the poles of the earth. it is because the temperature at the poles is minimum and it takes very low temperature to start the ozone depletion.
Antarctica would be most impacted by the thinning of the ozone layer. This thinning leads to the formation of the ozone hole over the region, which increases the exposure of harmful UV radiation to the surface. This has detrimental effects on marine life, ecosystems, and can also impact human health in the region.
If the ozone layer continues to deplete, there would be UV rays entering the surface of earth. These UV radiations cause various fatal problems to life on earth.
It is next to impossible thing to have no ozone in the atmosphere. Large solar mass ejections could cause some thinning of the ozone layer equal to, or greater than the worst thinning we are aware of (1859 sme event). Should this happen though, the sun's uv rays would react with the oxygen in our atmosphere and restore the ozone in short order. As long as we have oxygen and sunlight to react with it, we will have ozone.
If the depletion continues, UV will enter. These are fatal rays of the sun.
I would add more oxygen and bombard it with sunlight.
See "What would happen if the ozone layer vanished?"
The ozone depletion is a worldwide phenomenon. It should be stopped. Stopping ODS would slow it down.
The Ozone layer helps filter harmful rays from the sun. Less Ozone = Less filter = Higher cancer risk I'm only guessing on this part, but the ozone filters gamma rays and uv rays
It would probably create a localized ozone hole.
It is unlikely. The "hole" is not a hole at all. It is a thinning of the ozone layer (near each pole) that occurs annually during each poles winter. These are primarily caused by a lack of sun. The rest of this thinning is caused by solar activity, such as solar flares. The worst thinning of this layer occurred in 1858, which is also the year that recorded the worst solar activity. Even if we had massive solar flares, that did stripe the planet of all ozone in this layer, we would see the immediate rebuilding of this layer. Ozone is created by oxygen's contact with sunlight. This is why we only see this thinning during each poles winter and only in areas that see no sunlight for weeks at a time. No thinning is recorded at or near the equator.
If the ozone was being made at faster rate, nothing would happen. The UV would control that rate.
