Earth's protective ozone layer is slowly but noticeably healing at a pace that would fully mend the hole over Antarctica in about 43 years, a new United Nations report says.
A once-every-four-years scientific assessment found recovery in progress, more than 35 years after every nation in the world agreed to stop producing chemicals that chomp on the layer of ozone in Earth's atmosphere that shields the planet from harmful radiation linked to skin cancer, cataracts and crop damage.

Signs of healing were reported four years ago but were slight and more preliminary."Those numbers of recovery have solidified a lot," Newman said.
"There has been a sea change in the way our society deals with ozone depleting substances," said scientific panel co-chair David W. Fahey, director of the U.S. National Oceanic and Atmospheric Administration's chemical sciences lab. This is"saving 2 million people every year from skin cancer," United Nations Environment Programme Director Inger Andersen told The Associated Press earlier this year in an email.
