What is Ozone Layer Depletion? 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 Ozone depletion will intensify when the stratosphere becomes colder. Since global warming traps heat in the troposphere, less heat will be able to reach the stratosphere which will make it Ozone depletion is a result of the catalysed reactions between ozone and atomic chlorine or bromine. Chlorofluorocarbons (CFC) and bromofluorocarbons have the greatest ozone
Ozone Depletion - Essay
If the ozone layer was absent, millions of people would develop skin diseases and may have weakened immune systems. However, scientists have discovered a hole in the ozone layer over Antarctica. This has focussed their concern on various environmental issues and steps to control them. The main reasons for the ozone hole are chlorofluorocarbons, carbon tetrachloride, methyl bromide and hydrochlorofluorocarbons. 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 destroymolecules of ozone. It is destroyed more quickly than it is created. Some compounds release chlorine and bromine on exposure to high ultraviolet light, which then contributes to ozone layer depletion.
Such compounds are known as Ozone Depleting Substances ODS. The ozone-depleting substances that contain chlorine include chlorofluorocarbon, carbon tetrachloride, hydrochlorofluorocarbons, and methyl chloroform. Whereas, the ozone-depleting substances that contain bromine are halons, methyl bromide, and hydro bromofluorocarbons. Chlorofluorocarbons are the most abundant ozone-depleting substance. It is only when the chlorine atom reacts with some other molecule, it does not react with ozone. Montreal Protocol was proposed in to stop the use, production and import of ozone-depleting substances and minimise their concentration in the atmosphere to protect the ozone layer of the earth. Also Read: Environmental Issues. Ozone layer depletion is a major concern and is associated with a number of factors.
The main causes ozone depletion essay for the ozone depletion essay of the ozone layer are listed below:. 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, ozone depletion essay.
If not controlled, this might result in a huge loss of the ozone layer by the year The nitrogenous compounds such as NO 2NO, ozone depletion essay, N 2 O 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. that are 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:. Refrigerators, air-conditioners, solvents, dry-cleaning agents, etc. fire extinguishers, air-conditioners, solvents. Also Read: Global Warming.
The depletion of the ozone layer has harmful effects on the environment. Let us see the major effects of ozone layer depletion on man and environment. Humans will be directly exposed to the harmful ultraviolet radiation of the sun due to the depletion of the ozone layer. This might ozone depletion essay in serious health issues among humans, such as skin diseases, cancerozone depletion essay, 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 ozone depletion essay. The depletion of the ozone layer is a serious issue and various programmes have been launched by the government of various countries to prevent it.
However, steps should be taken at the individual level as well to prevent the depletion of the ozone layer. Reduce the use of ozone depleting substances. avoid the use of CFCs in refrigerators and air conditioners, ozone depletion essay, replacing the halon based fire extinguishers, etc. The vehicles emit a large amount of greenhouse gases that 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 ozone depletion essay with natural products to protect the environment. The government should take actions and prohibit the use of harmful nitrous oxide that is adversely affecting the ozone layer. People should be made aware of the harmful effects of nitrous oxide and the products emitting the gas so that its use is minimised at the individual level as well. Also Read: Our Environment Frequently Asked Questions What is ozone layer depletion? How does it occur? The thinning of the ozone layer present in the upper atmosphere is called ozone layer depletion.
Some chemical compounds release chlorine and bromine, which in exposure to high ultraviolet light causes the depletion of ozone. Examples are halons, chlorofluorocarbons, ozone depletion essay, hydrofluorocarbons, carbon tetrachloride etc. The Montreal Protocol is a global agreement which was proposed in the year The agreement focuses on protecting the ozone layer by minimising the production and consumption of ozone-depleting substances. Ozone layer helps in shielding the harmful ultraviolet rays of the sun. Depletion of the ozone layer exposes humans to harmful ultraviolet rays, this causes skin diseases, cataract, cancer, ozone depletion essay immune system etc. Put your understanding of this concept to test by answering a few MCQs.
