Hole in ozone is the thinning of this layer. To prevent it, curb the use of CFC's.
The ozone depletion is prevented by avoiding the use of CFC's. CFC's are the chemicals that destroy ozone.
The holes in ozone are not actually holes. They are lowered concentration of ozone.
The holes in ozone layer is the thinning of ozone. It is caused by CFC's.
The ozone layer cannot be prevented. However the ozone hole can be.
Holes in ozone layer is the thinning of ozone layer. It is because of use of ODS by humans.
Ozone holes are the thinning of ozone molecules. This is caused by man made or natural processes.
There are many holes in the ozone layer, the largest is above the south pole.
Ozone depletion is the process where ozone holes are created in the ozone layer. It is caused due to the action of chloro-floro-carbons on the ozone molecule to break it down to oxygen.
Holes in ozone layer are the thinning of ozone layer. They cause loss of life of flora and fauna.
Ozone layer is getting holes in it. It is due to the man made ODS's.
The ozone layer is not getting holes it it. Rather the concentration is falling below a certain level, which is defined as the ozone hole.
To prevent causing holes in ozone layer, we must stop the use of CFC's. They react with ozone to deplete it.
