Why is Ozone Day celebrated? World Ozone Day 2019
World Ozone Day is celebrated around the world on September 15 throughout the year. This year’s theme of Ozone Day 2019 is ’32 years and Healing’. The purpose of Ozone Day is to raise awareness for the protection of the return of Ozone. The ozone layer is a layer of ozone molecules that are found in the atmosphere within 20 to 40 km.
The ozone layer works to protect the Earth from the sun’s harmful ultra-violet rays. Without the ozone layer, life can be in danger. Because ultra-violet rays can get very dangerous to humans, tree plants and animals if they reach the ground directly. The protection of the ozone layer is very important in this. The ozone layer does a lot of damage to chemicals made by humans. The ozone layer is thinning with these chemicals. Chemicals emanating from factories and other industries are spreading pollution into the air. The ozone layer is undergoing climate change. The awareness campaign is being launched around the world to protect its security in the face of serious crisis.
