Ozone layer on track to recovery: UN report
"Earth's protective ozone layer is well on track to recovery in the next few decades, owing largely to the phase-out of certain chemicals used in refrigerants and aerosol cans, according to a new UN report.
Without the Montreal Protocol and associated agreements, atmospheric levels of ozone depleting substances could have increased tenfold by 2050, according to a summary document of the Scientific Assessment of Ozone Depletion 2014.
The Protocol will have prevented 2 million cases of skin cancer annually by 2030, averted damage to human eyes and immune systems, and protected wildlife and agriculture, according to UNEP."
