Finally a bit relief-ozone on a way to recovery

we have something to feel happy for our disturbed ozone layer, finally it's on the way to recovery, according to a comprehensive new assessment released on Wednesday.

Big thanks to a praiseworthy global attempt to stop or curb the use of ozone- depleting substances 

Approximately 300 scientists from 36 countries contributed to the comprehensive report, which was published by the United Nations Environment Program (UNEP) and the World Meteorological Organization (WMO).

So the point is why we are so concerned about ozone layer, well I think everyone has a brief knowledge about it but still if you don’t know, don’t worry. The ozone layer is a protective blanket of gas that protects us from harmful UV radiation releases by the Sun. Due to the excessive use of manufactured chemicals, especially manufactured halocarbon refrigerants, solvents, propellants and foam-blowing agents (chlorofluorocarbons (CFCs), HCFCs) referred to as ozone-depleting substances (ODS). These composite are transported into the stratosphere by the winds after being emitted from the surface.

It started to decline during the 1980s and in 1985 when scientists first time spotted a seasonal hole over Antarctica, immediately governments starting to take action to prevent further decline. Gases such as CFCs (chlorofluorocarbons) and halons—which were commonly used in products such as refrigerators and aerosols as discussed earlier can speed up the depletion of ozone in the Earth’s stratosphere, so scientists and politicians all over the globe put their heads together in a proposal to reduce their use. In 1987, almost 200 countries signed the Montreal Protocol which was designed to point out the use of ozone-depleting substances.

The ozone layer continued to decline throughout the early 1990s but then remained quite unchanged since 2000. The initiative taken to decreasing the usage of ozone-depleting gases, finally start showing signs of future recovery. According to the Montreal Protocol, it is estimated that atmospheric levels of these gases could have increased by 2050. Furthermore, according to the UNEP, the protocol will have prevented some two million cases of skin cancer annually by 2030, alongside protecting wildlife and agriculture.
