For years, scientists have been warning us that if the ozone layer kept getting thinner, cancer and eyesight problems would be more common. But here's some good news! Scientists have found out that the hole in the ozone layer above Antarctica is healing and they have proved it. Take a look.
The Hole Reached Its Biggest Size in 2006
Scientists Proved That the Hole Got Smaller Since 2000
It's almost 1,5 million square miles smaller than it used to be back then.
Hole above Antarctica Is Largest in October - Scientists Discovered It in 1985
So How Are We Responsible for the Hole in the Ozone Layer?
The main source that can harm the ozone is the organic compound called CFC found in devices such as fridges. Other things can harm it, too.
Sprays Destroy It
Especially hair-spray. It's full of CFCs!
Volcanoes Are Also Making the Ozone Thinner
Rocket Launches Should Be Reduced in Order to Save Ozone
But what was the cause of the healing of the ozone layer?
CFC Usage Got Banned on a Global Level
Countries around the world stopped making products with CFC in 2000.
Atmospheric Chlorine Also Got Reduced
And Usage of Pesticides Was Lowered
It All Contributed to the Shrinking of the Ozone Hole!
This is a great achievement, however, we'll need to wait for another 50 to a hundred years for the whole ozone layer to heal fully, so keep up the effort!
