Unraveling the Ozone Layer Hole: A Global Concern
Unraveling the Ozone Layer Hole: A Global Concern Introduction : The Earth's ozone layer, a vital shield against harmful ultraviolet (UV) radiation from the sun, has been facing a significant threat in the form of the ozone layer hole. This phenomenon, predominantly observed over Antarctica, has garnered widespread attention due to its potential impact on human health, ecosystems, and the environment. In this blog, we will delve into the causes, consequences, and global efforts to address the ozone layer hole. Causes of the Ozone Layer Hole: Ozone-Depleting Substances (ODS): The primary culprits behind the depletion of the ozone layer are human-made chemicals known as ozone-depleting substances. Chlorofluorocarbons (CFCs), halons, carbon tetrachloride, and methyl chloroform are among the key contributors. These substances release chlorine and bromine atoms when they reach the stratosphere, initiating a chain reaction that breaks down ozone molecules. Polar Stratospheric
