Chlorofluorocarbons or CFCs are the main cause of ozone layer depletion. These are released by solvents, spray aerosols, refrigerators, air-conditioners, etc. The molecules of chlorofluorocarbons in the stratosphere are broken down by ultraviolet radiations and release chlorine atoms. These atoms react with ozone and destroy it.
Researches say that the unregulated launching of rockets results in much more depletion of the ozone layer than the CFCs do. If not controlled, this might result in a huge loss of the ozone layer by the year 2050.
The nitrogenous compounds such as NO2, NO, N2O are highly responsible for the depletion of the ozone layer.
The ozone layer has been found to be depleted by certain natural processes such as Sun-spots and stratospheric winds. But it does not cause more than 1-2% of the ozone layer depletion. The volcanic eruptions are also responsible for the depletion of the ozone layer. Following is the list of some main ozone-depleting substances and the sources from ...
Humans will be directly exposed to the harmful ultraviolet radiation of the sun due to the depletion of the ozone layer. This might result in serious health issues among humans, such as skin diseases, cancer, sunburns, cataract, quick ageing and weak immune system.
Strong ultraviolet rays may lead to minimal growth, flowering and photosynthesis in plants. The forests also have to bear the harmful effects of the ultraviolet rays.
Planktons are greatly affected by the exposure to harmful ultraviolet rays. These are higher in the aquatic food chain. If the planktons are destroyed, the organisms present in the food chain are also affected. The depletion of the ozone layer is a serious issue and various programmes have been launched by the government of various countries to pre...
Reduce the use of ozone depleting substances. E.g. avoid the use of CFCs in refrigerators and air conditioners, replacing the halon based fire extinguishers, etc.
The vehicles emit a large amount of greenhouse gasesthat lead to global warming as well as ozone depletion. Therefore, the use of vehicles should be minimised as much as possible.
Most of the cleaning products have chlorine and bromine releasing chemicals that find a way into the atmosphere and affect the ozone layer. These should be substituted with natural products to protect the environment.

2 days ago · View the latest status of the ozone layer over the Antarctic, with a focus on the ozone hole. Satellite instruments monitor the ozone layer, and we use their data to create the images that depict the amount of ozone. Click any map image to bring up a new page with a high-resolution image.
Oct 26, 2022 · On Oct. 5, 2022, those satellites observed a single-day maximum ozone hole of 26.4 million square kilometers (10.2 million square miles), slightly larger than last year. The map at the top of this page shows the size and shape of the ozone hole over the South Pole on that day.
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.
Sep 18, 2012 · The destruction of the ozone layer allows more of the Sun’s ultraviolet radiation to reach the surface of the planet, increasing the risk of sunburns, skin cancer, and eye damage. The most prominent and infamous sign of depletion is the annual “ozone hole” that forms around the South Pole.
The political agreements were very effective. Since then, global emissions have fallen by more than 99%. The ozone holes have stopped growing and are now starting to close. This page includes all of our data, visualizations, and writing on the ozone layer, its depletion, and its path to recovery.
