Question

Do we have holes in our ozone layer ? If yes where and how big are they?

Answer 1

Yes..............the holes r there

Answer 2

The ozone layer is depleting in some places above Antarctica. It does not mean that the ozone layer has holes in it. It actually means that the ozone layer above Antarctica has less number of ozone molecules. The number of molecules in a particular area in ozone layer are less or in other words that particular area is most depleted but we say that there are holes in ozone layer.
