"Earth’s ozone layer protects all life on Earth from the sun’s harmful
radiation.
But in the late 20th century, human emissions of certain damaging chemicals
began to affect the number of ozone molecules in the atmosphere. This has
resulted in a dramatic hole opening up over Antarctica every year caused by
complex meteorological and chemical processes.
In 1987, just seven years after scientists discovered man-made chemicals were
damaging the ozone layer, the Montreal Protocol was signed to try and curb the
amount of harmful chemicals in the atmosphere.
Previously found in refrigerators, air conditioners, hair spray and industrial
cleaning products these chemicals started to be phased out to protect the ozone
layer. Agreed by all 197 parties, this was one of the first ever universally
ratified treaties in United Nations history.
Now, new research from the National Oceanic and Atmospheric Administration
(NOAA) in the US has found that concentrations of harmful chemicals that damage
the ozone layer have dropped."
