Designated by the United Nations, September 16 is observed as the international day for the Preservation of the Ozone Layer. This day is dedicated to protecting the delicate ozone layer that shields Earth from harmful ultraviolet (UV) radiation. India has been marking this important occasion since 1995.
The theme for world ozone day 2024 is “Montreal Protocol: Advancing Climate Actions,” which underscores the Montreal Protocol ’s vital role in both ozone layer protection and broader climate action efforts. World ozone day: Origin and significance World ozone Day originated in the 1980s when evidence revealed significant depletion of the ozone layer due to human activities. The ozone layer, located in the Earth's stratosphere, is essential for protecting life by absorbing harmful UV radiation .
The Montreal Protocol, adopted on September 16, 1987, was a pivotal international agreement to phase out ozone-depleting substances like CFCs and HCFCs, leading to notable improvements in ozone recovery. Understanding ozone layer Ozone (O3) is a reactive gas composed of three oxygen atoms. It can be either natural or man-made and is found in the Earth's stratosphere, which extends from 15 to 30 kilometres above the Earth's surface.
The term "ozone hole" refers to regions where the ozone layer has been significantly depleted, allowing harmful UV radiation to reach the Earth's surface. In the stratosphere, ozone is produced naturally through the interaction of solar UV light with mo.
