"The Earth's ozone layer is on its way to recovering, thanks to decades of work
to get rid of ozone-damaging chemicals, a panel of international experts backed
by the United Nations has found.
The ozone layer serves an important function for living things on Earth. This
shield in the stratosphere protects humans and the environment from harmful
levels of the sun's ultraviolet radiation.
The international community was alarmed after experts discovered a hole in the
ozone layer in May 1985. Scientists had previously discovered that chemicals
such as chlorofluorocarbons, used in manufacturing aerosol sprays and used as
solvents and refrigerants, could destroy ozone.
Two years after the discovery of the dire state of the ozone layer,
international bodies adopted a global agreement called the Montreal Protocol.
This established the phaseout of almost 100 synthetic chemicals that were tied
to the destruction of the all-important ozone.
In the latest report on the progress of the Montreal Protocol, the U.N.-backed
panel confirmed that nearly 99% of banned ozone-depleting substances have been
phased out.
If current policies stay in place, the ozone layer is expected to recover to
1980 values by 2040, the U.N. announced."
