Ozone layer depletion is the thinning of the ozone layer that protects the earth from the harmful UV radiations. Explore the causes, effects, and solutions to ozone layer depletion only at BYJU'S.
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 (the ozone layer) around Earth's polar regions.
Jun 27, 2024 · 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.

But, during the 1970s, ‘80s, and ‘90s, humans were emitting large quantities of substances that depleted the ozone layer. This led to the creation of ozone holes at the earth’s poles, exposing life to higher levels of ultraviolet radiation and increasing the risks of skin cancer in humans.
Oct 16, 2019 · Left: Ozone in Earth's stratosphere at an altitude of approximately 12 miles (20 kilometers) in mid-March 2011, near the peak of the 2011 Arctic ozone loss. Red colors represent high levels of ozone, while purple and grey colors (over the north polar region) represent very small ozone amounts.
The 2022 WMO/UNEP Ozone Assessment contains the most up-to-date understanding of ozone depletion, reflecting the thinking of hundreds of international scientific experts who contribute to its preparation and review.
Sep 15, 2021 · Around 99 per cent of ozone-depleting substances have been phased out and the protective layer above Earth is being replenished. The Antarctic ozone hole is expected to close by the 2060s, while other regions will return to pre-1980s values even earlier.
Jun 24, 2019 · Ozone depletion has also contributed to climate change across the Southern Hemisphere. These changes are interacting in complex ways to affect human health, food and water security, and...
