Unless you strongly believe in Elon Musk‘s idea of making Mars as another habitable planet, do remember that there really is no 'Planet B' in this whole universe.Conserve Energy Future is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com. 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 where they are released:The depletion of the ozone layer has harmful effects on the environment. While naturally occurring chlorine has the same effect on the ozone layer, it has a shorter life span in the atmosphere.Of all of the causes of ozone depletion, the release of CFCs is thought to have accounted for 80% of all stratospheric ozone depletion. The thinning is most pronounced in the polar regions, especially over Antarctica.

The Effect of CFCs Scientists first began to realize the potential for chlorine to interact destructively with ozone in the early 1970s, and Sherwood Rowland and Mario Molina warned of the danger that CFCs posed to the ozone layer in 1974. Utilize Environmentally Friendly Cleaning Products ← What is a Rainforest? Because of their relative stability, CFCs rise into the stratosphere where they are eventually broken down by ultraviolet (UV) rays from the Sun. 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. Ozone is an extraordinary kind of oxygen composed of 3 oxygen atoms instead of the normal 2 oxygen atoms. These vehicles emit a lot of The Montreal Protocol formed in 1989 helped a lot in the limitation of Chlorofluorocarbons (CFCs). The first one has been a slow, but steady ozone depletion of 4% per decade of the Earth’s stratosphere(ozone layer). They do this by simply stripping off an atom from the ozone molecule. The protocol also developed a fund to help underdeveloped countries to find other methods of production so that they could stop using CFCs and HCFCs, also.The Guide to Space is a series of space and astronomy poddcasts by Fraser Cain, publisher of Universe TodayEpisode 680: Interview with Fraser on Awesome AstronomyClick to email this to a friend (Opens in new window) The main reasons for the ozone hole are chlorofluorocarbons, carbon tetrachloride, methyl bromide and hydrochlorofluorocarbons.Let us have a detailed look at the various causes and effects of ozone layer depletion.Ozone layer depletion is the thinning of the ozone layer present in the upper atmosphere. One chlorine can destroy 100,000 molecules of ozone. The chlorine reacts with oxygen which leads to the chemical process of destroying ozone molecules. Changes in UV levels is know to affect both orientation and motility in phytoplankton. Nitrous oxide is still in use today. Once they get there they destroy ozone molecules and cause the ozone layer to become depleted or thinner. However, the protocol never covered nitrous oxide, which is a known harmful chemical that can destroy the ozone layer.

UV radiation has an effect upon the fertility of … When she is not writing, she loves watching sci-fi movies on Netflix.20+ Most Amazing Benefits of Trees That Are 100% TrueWhere is the Ozone Layer Located and Importance of Ozone LayerWhat Causes Seasons and What are Different Seasons? There are many causes for ozone depletion, but the most important process in both trends is catalytic destruction of ozone by atomic chlorine and bromine. Forests equally bear the brunt of ozone depletion.Also, overexposure of sun rays could reduce the fortunes of fishers. CFCs (chlorofluorocarbons), halons, CHThe problem with the Ozone-Depleting Substances (ODS) is that they are not washed back in the form of rain on the earth and in-fact remain in the atmosphere for quite a long time. On the downside though, because CFCs remain in the atmosphere so long, the ozone layer will not fully repair itself until at least the middle of the 21st century.The Montreal Protocol is an international agreement to address the causes of ozone depletion. It has the potential to absorb around 97-99% of the harmful ultraviolet radiations coming from the sun that can damage life on earth. The ozone layer normally develops when a few kinds of electrical discharge or radiation splits the 2 atoms in an oxygen(O2) molecule, which then independently reunite with other types of molecules to form ozone. However, various factors have led to the depletion and damage of this protective layer. CFCs Get Banned In 1974 scientists Sherry Rowland and Mario Molina discovered the link between the depletion of the ozone layer and CFCs. The This lower region of the stratosphere containing a relatively higher concentration of ozone is called Ozonosphere. When she is not writing, she loves watching sci-fi movies on Netflix.Sonia Madaan is a writer and founding editor of science education blog EarthEclipse. Ozone is very efficient at absorbing the sun’s ultraviolet (UV) radiation even in very small amounts.

While several substances were addressed, CHCs and HCFCs were the main ones that the international community agreed to phase out of production. It has also been linked to damage to some materials, crops, and marine organisms. The physiological and developmental processes of plants are also severely affected apart from the growth. Depletion of the ozone layer has consequences on humans, animals and plants. The ozone layer protects the Earth against most UVB coming from the sun. While several substances were addressed, CHCs and … Causes of Ozone Layer Depletion. Ozone depletion is primarily caused by human activities. They take from 20 to 120 years to break down. These are higher in the aquatic food chain.
