Antarctic Ozone Hole Heals

It takes a while, but improving the environment can work. The actions taken to cure the ozone hole over Antarctica are making measurable progress. Legislation was passed in 1987 to restrict the chemicals that were creating the hole.

“The scientists’ finely tuned climate model also found that the ozone hole over Antarctica in the month of September shrank by 4.5 million square kilometers, on average, between 2000 and 2015.” – Scientific American

The hole, which varies throughout the year, is also opening later every year. The situation won’t return to normal for decades, possibly more than a century from now, but it is an example of how humans can cause and cure at least some environmental impacts. It is possible but takes a long time. Not all upsets are the same, but we’ve made progress against at least this one.
