It’s about time we heard some good news on the environmental front: You know that gaping hole in the ozone layer above Antarctica? Well it’s on the mend.
Who says the human race can only band together to prevent catastrophe in action movies?
Scientists first noticed the deterioration of the Earth’s protective layer in the ‘70s and the continuation of it could have resulted in soaring skin cancer rates or harmed Earth’s crops and the marine food chain (it would have been a lot worse than it may sound).
The villain in this story is Chlorofluorocarbons (CFCs), a fancy name for chemicals that were widely used in refrigerators and spray cans back in the day, and its fellow chemical-minions. But against all odds, world leaders united against this formidable foe with the 1987 Montreal Protocol in hand; this weapon of choice called for the abolishment of CFCs ignoring industry cries about increased expenses.
Pollution put up a good fight, though. The ozone continued to deteriorate with another major hole appearing in 2006. However, slowly but surely things have at last began to improve. Eat that, chemicals!
Like every open wound, though, our ozone will take time to heal. In a press statement, UN Under-Secretary-General Achim Steiner mentioned that, “There are positive indications that the ozone layer is on track to recovery towards the middle of the century.”
It was a very close call, and we shouldn’t do our victory dance just yet, but this is a beacon of hope—green can prevail! Know more.
