Remember the ozone hole over Antarctica? It was discovered in 1985 and linked to pollution. There was great debate, but eventually the damaging chemicals were heavily regulated. Now, more than thirty years later, the hole continues to heal, though with meteorological variations. At its current rate, the hole should reduce to 1980 levels by 2070. While the hole is rarely mentioned, and has reached a recent record low, the hole is still massive at;

19.6 million square kilometers (7.6 million square miles), an area about 2.5 times the size of the United States.” – NASA Earth Observatory

The bad news is that the hole exists and we helped create it.

The good news is that we saw the data, acted on it, and have been able to undo some of the damage.
