The hole in the ozone, which is always measured at its peak in September, is bigger than ever this year. Last year it was reduced and the scientists were happy, but it turns out their joy was premature. This year, the hole is back to normal

The man-made hole in the ozone layer over Antarctica has reached a record size for the first time since they started measuring it, and that it may grow even larger in the coming days. This is what a scientist who studies the ozone layer in the South Pole said on Friday.
The area of the hole this year, slightly less than 28 million square kilometers, is only slightly below the record of 28.5 measured last month, but from past events it is known that in the second week of September it grew even more and therefore it can break the record. This is what Jonathan Shanklin said , a scientist on the British Antarctic Survey Expedition.
"It was at its peak during August, and we're looking forward to seeing what happens in the next few days," Shanklin said.
As you remember, the ozone layer in the stratosphere protects the earth from the damage of the sun's ultraviolet rays - especially lung cancer.
In 2002 the hole suddenly shrank, raising hopes that it would reverse course and begin to close, but Shanklin said scientists believe it was an anomaly caused by rare atmospheric conditions and that the 2003 expansion indicates a return to normal activity.
Shanklin says that the use of chemicals by humans all over the world causes the depletion of the ozone layer as a whole, and in particular in the areas above the South Pole.
