Ozone layer is a patch of atmosphere with high concentrations of ozone. Ozone is a gas comprising three atoms of oxygen O3. It can either damage life, or protect life on Earth, depending on where the ozone layer is.

Most ozone exists within the stratosphere. In fact, at this layer, it serves as a barrier that shields the Earth’s surface from the sun’s harmful ultraviolet emission. However, if this barrier were to collapse; people would be more vulnerable to weakened immune systems, cataracts and skin cancer.

How it Started

In 1994, the UN General Assembly declared the International Day for protecting the Ozone Layer on 16th Sept. Also, they commemorate the date of the signing, in 1987. That was under the Montreal Protocol on diminishing stratospheric ozone intoxicants. They launched it on 1st January 1989. The goal of this Montreal Protocol was to control gases that hurt the ozone layer by the year 2050. As per this protocol, they also decided it that the production and use of gases such as chlorofluorocarbons that destroy the ozone layer would set to a certain limit. In fact, India also was the part of that summit. The theme of this year’s World Ozone Day is ‘Ozone for Life’.

Experts detected closure of the hole in the ozone layer 30 years after the signing of the protocol. They expect their chemical effects to go on for between 50 and 100 years. It is because of a nature of the gases responsible for ozone depletion.

Without sunshine life on Earth wouldn’t be possible. But if not for the ozone layer, the emission deriving from the sun would be too much for life on Earth to survive. This stratospheric layer shields Earth from the nasty, ultraviolet radiation of much of the sun. The ozone layer, or also known as the Ozone shield is a thin layer of gas, blocks. It protects much of the ultraviolet rays of the Sun in the earth’s stratosphere itself. These rays can lead to various skin illnesses.
