ozone layer

There are signs of progress more than 35 years after every nation in the world agreed to stop producing chemicals that harm the ozone layer.
Since the 1970s, the ozone layer has slowly become thinner, now, the ozone layer is slowly being repaired.
In a rare -- and much-needed -- environmental win, a UN report says parts of the ozone layer could be fully healed by the 2030s.
"We can now be confident that the things we’ve done have put the planet on a path to heal," one scientist says.
