Write any two effects of depletion of ozone layer

Ozone present in the lower atmosphere is regarded as a pollutant and a greenhouse gas, that can contribute to global warming and climate change.

ODS are relatively stable in the lower atmosphere of the Earth, but in the stratosphere, they are exposed to ultraviolet radiation and thus, they break down to release a free chlorine atom. At individual level each and everyone also can contribute towards reducing ozone layer depletion.

Health and Environmental Effects of Ozone Layer Depletion

This eventually disturbs and affects the entire ecosystem. There are two regions in which the ozone layer has depleted. Description The ozone layer is what saves the Earth and the living organisms from the harmful radiations of the sun.

What are the causes and effects of ozone depletion?

The downside to halons is they are so potent that they are able to deplete the ozone layer 10 times more than ozone-depleting substances.

The substance is also utilized in foam products like mattresses and cushions and home insulation. Such international agreements have succeeded to a great extent in reducing the emission of these compounds.

An increase in UV-B rays can mean smaller leaf size, decreased plant growth, and lower quality crops for humans. One of the largest such hole appears annually over Antarctica between September and November.

This leads to their breakdown and releasing of free chlorine atoms which reacts with the ozone gas, thus leading to the depletion of the ozone layer. It is also one of the prime reasons which are leading to global warming.

UV rays affect other life forms too. The Ozonosphere is found km 9 to 22 miles above the surface of the earth. Ultraviolet radiation could destroy the organic matter. In this research paper you will also find out what the ozone layer actually is and the parts that it is composed of.

Because CFCs are so stable, only presentation to harsh radiation could break them down. Ultraviolet rays are also capable of destroying single cell organism, terrestrial plant life, and aquatic ecosystems. Because they release chlorine and bromine when they breakdown, they damage the protective ozone layer.

Examples are methyl bromide use in pesticides, methyl chloroform used on making industrial solvents, and halons used in fire extinguishers. A lot of human activities such as gas balloons, mountain climbing, and small aircraft flights take place within this region.

This, essentially, implies that a lot of the ozone-depleting substances human have allowed to go into the atmosphere for the previous 90 years are still on their journey to the atmosphere, which is why they will contribute to ozone depletion.

You too can do your bit to save the ozone. Research scientists have anticipated disruption of susceptible terrestrial and aquatic ecosystems due to depletion of ozone layer.

List of the seven continents and the 5 oceans of the world. Effects on Marine Ecosystems Phytoplankton form the foundation of aquatic food webs.

In the aquatic food chain, planktons appear high up. At the same time, increase in the level of ozone in the lower atmosphere can enhance the ability of sunlight to synthesize vitamin D, which can be regarded as an important beneficial effect of ozone layer depletion.

One method instituted was to ban the use of CFCs. When that happens, the CFC molecule releases atomic chlorine. At any given time, ozone molecules are constantly formed and destroyed in the stratosphere.

May 10, Answer: Bromine atom is believed to be 40 times more destructive than chlorine molecules. The free oxygen atom Othen combines with an oxygen molecule O2and forms a molecule of ozone O3. Thanks to the ozone layer which protects us from these harmful rays.

These are categorized as ozone-depleting substances ODS.there are many harmful effects of ozone layer depletion. - harmful effects of ozone layer depletion are: damage to DNA and leads to mutation damage to skin cells ageing of skin cause various types of cancers snow blindness cataract thus, ozone layer depletion cause very harmful effects.

Depletion of the Ozone Layer: Its causes, effects, and possible solutions Essay Sample The depletion of the ozone layer is a major concern today. The ozone layer protects us from the harmful rays of the sun; therefore it is imperative that we preserve it.

The ozone layer is responsible for absorbing harmful ultraviolet rays, and preventing them from entering the Earth's atmosphere. However, various factors have led to the depletion and damage of this protective layer. Learn more about the process, causes, and effects of ozone layer depletion.

Effects of ozone layer depletion. Let us see a few possible effects of the ozone layer depletion on the earth’s environment and also on the plants and animals. The depletion of ozone layer allows entering of UV rays from sun into the earth’s atmosphere which is associated with a number of health related and environmental issues.

Natural causes of depletion of ozone layer: Ozone layer has been found to be affected by certain natural phenomena such as Sun-spots and stratospheric winds. But this has been found to cause not more than % depletion of the ozone layer and the effects are also thought to be only temporary.

have significant effects on the environment. Ozone layer damage is one of them. The objective of this paper is to review the origin, causes, mechanisms and bio effects of ozone layer depletion as well as the protective measures of this vanishing layer.
