Ozone depletion consists of two related events observed since the late 1970s: a steady lowering of about four percent in the total amount of ozone in Earth's atmosphere, and a much larger springtime decrease in stratospheric ozone around Earth's polar regions. The latter phenomenon is referred to as the ozone hole.
The lowering of the ozone layer in the high atmosphere is referred to as ozone layer depletion. That is damaging to the environment and nature. Depletion of the ozone layer is a huge issue for the atmosphere as well as all living things on the planet, including the flora and wildlife.
Explanation:
Depletion of the ozone layer: Ozone molecules are destroyed when chlorine and bromine atoms come into touch with them in the stratosphere. Before being evacuated from the stratosphere, a single chlorine atom can damage over 100,000 ozone molecules. Ozone can be depleted faster than it can be generated naturally.
The gradual thinning of the Earth's ozone layer in the upper atmosphere caused by the discharge of chemical compounds containing gaseous chlorine or bromine from industry and other human activities is referred to as ozone depletion.
Causes:
Produced chemicals, particularly manufactured halocarbon refrigerants, solvents, propellants, and foam-blowing agents (chlorofluorocarbons (CFCs), HCFCs, halons), are the primary cause of ozone depletion and the ozone hole.
