The Earth's ozone layer will make a full recovery in 50 years.

The hole in the Earth's ozone layer is expected to fully heal within 50 years, climate change experts predict in a new UN report.
A fragile shield of gas around the planet, the ozone layer protects animal and plant life from the powerful ultraviolet (UV) rays of the sun. When the ozone layer is weakened, more UV rays can get through, making humans more prone to skin cancer, cataracts and other diseases.
Scientists discovered huge damage to the layer in the 1980s and identified chlorofluorocarbons, or CFCs, as the main culprit.
