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.
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.
We must be very concerned. It is because ozone hole allows harmful UV to pass through.
Scientists are concerned about the ozone depletion. It is because this depletion can cause extinction of human race.
Some scientists are concerned about ozone loss. It is because it will allows fatal UV rays to pass through.
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.
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.
Yes, we should be concerned that the ozone layer is decreasing because it acts as a shield for the earth. It protects us from the harmful ultraviolet radiations of the sun.
They help deliver water vapor to high altitudes. They produce new compounds that may not be assessed for their effect on the ozone layer.
Ozone is present in the stratosphere of the earth's atmosphere. It is in this region that the scientists are concerned.
The ozone layer protects us from UV rays. If it is not there, there will be no life on earth.
Scientists are concerned about the ozone hole. They are trying to ban the CFC's over the world.
