Every year 16 September is marked as the International Day for the Protection of the Ozone Layer.
The layer may be a gradient of gas that protects the planet from the harmful a part of the sun’s rays and so helps preserve life on the earth.

The theme of the day for 2019: 32 years and healing-
The theme of the day for 2019 is 32 years and healing. The theme of this year celebrates three decades of remarkable international cooperation to protect the ozone layer and climate under the Montreal Protocol. It also reminds people to keep pace to ensure healthy people and a healthy planet. In 2018, the latest scientific evaluation of ozone depletion was completed. This assessment suggests that parts of the ozone layer have recovered since 2000 at a rate of 1–3% per decade. Even at protected rates, the northern hemisphere and mid-latitude ozone will fully recover by 2030. The Southern Hemisphere will last until 2050 and 2060 in the polar regions. There is no doubt that the ozone layer protection efforts also contribute to fighting climate change.
This year’s theme celebrates three decades of notable international cooperation to protect the ozone layer and climate under the Montreal Protocol. The Montreal Protocol has led to the phase-out of 99 per cent ozone-depleting chemicals in refrigerators, air-conditioners, and many other products.


What is the ozone hole?
The ozone hole is not technically a “hole” where no ozone is present but is actually an area of exceptionally low ozone in the stratosphere above the Antarctic that occurs in the early spring of the Southern Hemisphere.
The ozone layer was discovered in 1913 by French physicists Charles Fabri and Henri Bison.
