Ozone Depletion: Natural disasters causing ozone depletion

Natural disasters like volcano’s play a minor role in ozone depletion. The gases evolved during eruption of volcano's are chloroflurocarbons, hydrofluorocarbon carbons ..etc., causes not only ozone depletion but also cause many global wide problems like acid rains, global warming, water pollution, causing extinction of many animal species for example dinosaurs. The eruption of volcano reaches the stratosphere of earth atmosphere where ozone is present. Many dangerous toxic gases release from this eruption. Due to high heat energy the evolved gas covert in to free radicals and this free radicals are mostly halogens ex:Cl^- and F^- this will react with Ozone and covert it into oxygen. As per NOAA scientist one atom of chlorine or fluorine free radical can covert 100000 molecules of Ozone in to oxygen, and thus deplete ozone layer.

Another natural disaster is Oceans. Oceans contain many types rock salts which are composed of halogens like chlorine and fluorine. And also many industrial waste containing halogen are dumping in to oceans which leads to increase in salt content in oceans .also some volcanic eruption in oceans cause rise of level of halogen in oceans. Global warming cause the rise of temperature which leads to evaporation of oceans salts release halogen free radicals which goes up and react with Ozone layer cause ozone depletion.

In summer, Forest fire is also one of the major reason for the evolution of some ozone depleting gases like carbon monoxide, nitrogen oxide etc., which causes Ozone depletion. And also deforestation which is not a natural disaster but human are made it as natural disaster by expanding the city by cutting tress and building house.
