Explanation:

Both the statements are correct.

The findings showed that an international ban on chlorine-containing manmade chemicals called chlorofluorocarbons(CFCs) has resulted in about 20 per cent less ozone depletion during the Antarctic winter from 2005 to 2016.
CFCs are long-lived chemical compounds that eventually rise into the stratosphere, where they are broken apart by the Sun's ultraviolet radiation, releasing chlorine atoms that go on to destroy ozone molecules.
Stratospheric ozone protects life on the planet by absorbing potentially harmful ultraviolet radiation that can cause skin cancer and cataracts, suppress immune systems and damage plant life.
