What are scientists doing to repair the ozone layer?

Some believe that they have found that the ozone layer is being damaged, reported it.

Politicians have then pushed and been a pain-in-the-tush to make sure some candidate chemicals were banned while scientists continue to prove their theory.

They helped kill the Concorde, which was shown to damage the ozone layer.

(Not true! The Concord flight was discontinued due to age of the aircraft and a major incident killing everyone on board due to their age.)

Most of them are implementing personal choices that reduce their contributions to ozone layer depletion.

Most Science experts agree that the Ozone layer's thinning is only at the poles and only during their winter months. They realize that the vast bulk, if not all, of the thinning is natural and due to a lack of sunlight. The banning of chemicals that are heavier then air to help a portion of our atmosphere that is very high is actually a very hard sell. Logic and honesty can not be used. Items heavier then air seldom fly to levels of 50,000 feet.

They also realize that the greatest thinning (thus the largest hole) happened in the 1830's which was well before cfc's were in use. We know that this "hole" is caused by a lack of sunlight in the affected areas, not cfc's.
