Ozone depletion | Facts, Effects, & Solutions | Britannica
Ozone depletion, gradual thinning of Earth’s ozone layer caused by the release of chemical compounds containing gaseous chlorine or bromine from industry and other human activities. The thinning is most pronounced in the polar regions, especially over Antarctica.
Ozone depletion - Wikipedia
The ozone layer prevents harmful wavelengths of ultraviolet(UVB) light from passing through the Earth's atmosphere. These wavelengths cause skin cancer, sunburn, permanent blindness, and cataracts,[5]which were projected to increase dramatically as a result of thinning ozone, as well as harming plants and animals.
Health and Environmental Effects of Ozone Layer Depletion
2024年7月16日 · ozone depletion. A chemical destruction of the stratospheric ozone layer beyond natural reactions. Stratospheric ozone is constantly being created and destroyed through natural cycles. Various ozone-depleting substances (ODS), however, accelerate the destruction processes, resulting in lower than normal ozone levels.

Ozone Layer Depletion - Cause, Effects, And Solutions - BYJU'S
Ozone layer depletion is the thinning of the ozone layer present in the upper atmosphere. This happens when the chlorine and bromine atoms in the atmosphere come in contact with ozone and destroy the ozone molecules. One chlorine can destroy 100,000 molecules of ozone. It is destroyed more quickly than it is created.
