Answer 1

Although the regulations made in the emission of chemicals has reduced the damage but the results are nowhere near to what were predicted. Also it’s very difficult to tell the exact changes as a number of environmental factors are also involved in damage of ozone layer along with man made causes.

Yes the size of ozone has changed in recent years. It has increased by 36%.
