Yes. Since the Montreal Protocol to phase out CFC emissions was signed in 1989 levels of this dangerous man-made gas in the atmosphere are falling. Scientists think the ozone layer will return to its original levels by about 2050.
Ozone is decayed back to oxygen. It depends on how the ozone is being converted.
The ozone hole is quite big. It will grow or shrink depending on CFC usage.
Air pollution causes ozone depletion. The gases react with ozone to deplete.
Ozone layer can be replenished naturally.
If CFC's cannot be used the ozone level will grow again in the next 60 - 120 years
Ozone layer helps to maintain the appropriate temperature. This helps plant grow and survive.
All ozone does not change back into oxygen. It is because that ozone is continuously interacting with UV radiations.
The ozone hole grows and shrinks. It is because of the CFC levels each other.
yes it does grow and does it become stronger
The ozone appeared long back. Before the mankind was born.
The ozone hole was not there 2000 years back. No CFC's were there then.
Since they serve to enrich soil for plants to grow in, they help plants release oxygen, from which ozone is made.
