Essay title: Ozone Depletion

❶The chlorine ion catalyzing O 3 depletion can take place in the gaseous phase, but it is dramatically enhanced in the presence of polar stratospheric clouds. For the ozone layer to return to its natural state, the chlorine loading which is presently 3 ppbv has to be brought down to a level below 2 ppbv.

UV rays will also affect the plants. UV radiations can alter the time of flowering in some plant species. It can also directly affect the plant growth by altering the physiological and developmental processes of the plants. Ozone layer depletion leads to decrease in ozone in the stratosphere and increase in ozone present in the lower atmosphere.

Presence of ozone in the lower atmosphere is considered as a pollutant and a greenhouse gas. Ozone in the lower atmosphere contributes to global warming and climate change. The depletion of ozone layer has trickle down effects in the form of global warming, which in turn leads to melting of polar ice, which will lead to rising sea levels and climatic changes around the world.

Ozone layer depletion is not something that affects any specific country or region. The whole world is vulnerable to its after effects. That makes it important for each and every one of us to take actions to reduce ozone layer depletion.

International agreements such as Montreal protocol in have helped in reducing and controlling industrial emission of Chlofluorocarbons. More and more of such international agreements between countries is necessary to bring down ozone layer depletion.

At individual level each and everyone also can contribute towards reducing ozone layer depletion. Buying and using recycled products, saving of energy, using of public transport can do a lot in combating ozone layer depletion. The most important thing that we can do is spreading awareness. The ozone layer is what saves the Earth and the living organisms from the harmful radiations of the sun. It is necessary to understand its importance and work to control the depletion of this layer.

This helped me in doing the homework, ill check regularly for researches for science and these kinds of stuff Best site ever for science! It is very good knowledge about ozone layer in simple words.

Nice……all the information about ozone…… a good way of awareness. Very very helpful for school project. Thanks to the site. Its to good information which help in my study. It was helpful for my project work.. Leave a Reply Cancel reply Your email address will not be published. The free chlorine molecule again reacts with ozone to form chlorine monoxide. The process continues and the result is the reduction or depletion of ozone in the stratosphere.

Effect of Ozone Depletion. Therefore, these factors bring a lot of problem on our daily life. For examples, LensMan unknown stresses that the ozone depletion will lead an increase in the percentage of skin cancer and cataracts. In addition, figure 1 from the reference shows that the UV radiation may damage crops, kill plankton that serve as a food source for marine life. The human immune system also will be affected. CFCs may trap heat and thus contribute to the global warming.

As ScienceDaily shows ozone hole linked to climate change all the way to the equator. This proves ozone depletion is a big issue that needs attention. Hence, we should be aware and actions must be taken to ensure that ozone layer is not destroyed. But it is difficult to do so because so many products including refrigerator, air-conditioning, cleaning agents and so on contains this product. CFCs would remain in the stratosphere for another years if none we have taken for the problem.

Harankhedkar Many other countries have signed treaties and written laws restricting the use of CFCs. Companies are finding substitutes for CFCs, and people in general are becoming more awareness of the dangers of ozone layer depletion.

At last, The Montreal Protocol has resulted in stopping additional ozone loss and investigated by experts ver 4 years survey on ozone depletion Earth Day was first observed on 22 April An estimated 20 million people nationwide attended this festivity which came the largest grassroots environmental Besides that, not only the government but also the residents have a role to play and avoid ozone depletion.

We should always unplug or switch off the electronic instruments when they are not in use. We also are encouraged to walk and avoid using vehicles if we can.

Simple measures like using public transportation instead of our own private vehicle will help a big deal. We can plant trees from now as they produce oxygen and absorb the UV rays greatly. We are suggested to use the renewable sources, for examples, wind, solar energy, and so on. Brack reminds the United Nations officers that they have a role to play to produce and ensure that the new equipment purchased is ODS-free. Conclusion As you see, most ozone depletion resulted from the human activities.
