Scientists are concerned about *features* of the ozone hole, not the hole itself. How early it starts, how little ozone is found in it, how long it lasts, How big it gets... these are the things the scientists concern themselves with. An ozone hole forms at the pole that is experiencing late winter / early spring, whether Man messes with it or not.
And the ozone hole appears above areas that are not yet getting significant UV-B to be protected from.
Scientists are concerned about the depletion of ozone levels because the ozone layer acts as a shield that protects Earth from harmful ultraviolet (UV) radiation from the sun. Depletion of the ozone layer can lead to increased UV radiation reaching the Earth's surface, which can have harmful effects on human health, wildlife, and ecosystems.
Troposphere ozone is a pollutant. It should not be protected.
All scientists are concerned about the ozone layer, but since international action to stop production of CFCs (Chloro-fluoro-carbons) the problem is not as bad as before.

Scientists have many theories. According to them, ozone was created by UV rays.
Some scientists are concerned about ozone loss. It is because it will allows fatal UV rays to pass through.
Scientists are concerned about the depletion of ozone levels because the ozone layer acts as a shield that protects Earth from harmful ultraviolet (UV) radiation from the sun. Depletion of the ozone layer can lead to increased UV radiation reaching the Earth's surface, which can have harmful effects on human health, wildlife, and ecosystems.
We must all be concerned about ozone layer. It is because this layer is depleting.
Troposphere ozone is a pollutant. It should not be protected.
Scientists are concerned about the ozone depletion. It is because this depletion can cause extinction of human race.
We must be very concerned. It is because ozone hole allows harmful UV to pass through.
We are concerned with ozone because ozone layer blocks about 97% of the the total received by the earth. Ozone depletion will expose earth to harmful radiations and will burn the life. The temperature will increase and make earth inhabitable place.
Ozone is disappearing. It is because of the increasing CFC's.
Dr. Farman told that. he said we have hole in the ozone.
All scientists are concerned about the ozone layer, but since international action to stop production of CFCs (Chloro-fluoro-carbons) the problem is not as bad as before.
We must be concerned about ozone destructionas it will allow UV rays to enter the earth. These UV rays are fatal to life on earth.
