New Ozone Hole: A huge-sized new ozone hole has been detected in the tropical region of the Earth. It is seven times bigger than the ozone hole of the Antarctic. This hole has the potential to affect almost half of the population.

Ozone is a gas molecule that is highly reactive and is made up of three atoms of oxygen. It is formed in the stratosphere or in the Earth’s atmosphere’s higher levels. In these layers, the sunlight and the molecular oxygen meet and react. The layer actually acts as a savior for the Earth and its habitants as it helps in maintaining the temperature.

The ozone layer is constantly formed and destroyed, and its total amount remains relatively stable in the atmosphere. But due to the presence of certain chemicals, the layer can get destroyed fast, and it results in depleted levels of ozone.

Due to a hole in the ozone layer, ground-level UV radiations are increased and can have extremely harmful effects on living beings, plants, etc. In essence, it can destroy the entire ecosystem.

The ozone hole lying over the area of Antarctica was found in the 1980s.

How is an ozone hole formed?

An ozone hole is formed when the level of ozone in the area gets depleted by more than 80%. Various chemicals like chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), methyl chloroform, and carbon tetrachloride impact the ozone layer adversely and become the cause of ozone holes.

Qing-Bin Lu and his colleagues have discovered this new hole. Lu is working as a professor at the University of Waterloo in Canada. Their findings have been published in the American Institute of Physics journal. In the report, Lu mentioned that this hole existed since the 1980s but could be discovered now. Also, he does not consider 80% destruction in the ozone layer as a hole. According to him, even 25% of destruction is a hole.
