A large hole in the Earth’s protective ozone layer is finally starting to show signs of healing up.
Situated high up in the planet’s stratosphere, the ozone layer is a special region which helps to protect the Earth from harmful ultraviolet radiation coming from the sun.

Scientists first noticed that it appeared to be thinning above Antarctica back in the 1980s, a worrying trend that was shown to be due to the presence of certain chemicals in hair sprays, refrigerators, air conditioning systems .
now scientists have revealed that there has been a distinct improvement in the ozone layer over Antarctica.

New data has shown that the area of thinning has reduced by 4 million square kilometers since the year 2000 – that’s a region roughly the size of India.
