Ozone Layer Concern is a term used to describe the environmental issue of the depletion of the ozone layer. This is caused by the release of certain chemicals, such as chlorofluorocarbons (CFCs), into the atmosphere. The HOLE in the ozone layer is located in the stratosphere and is caused by the breakdown of ozone molecules due to the presence of CFCs. This has led to an increase in the amount of ultraviolet radiation reaching the Earth's surface, which can have serious health and environmental consequences.
