It usually acts as a protective shield for the earth and the environment and protects it from the dangerous ultra-violet rays of the sun.
Life forms cannot survive without the ozone layer because the ozone layer protects us from harmful ultraviolet rays that radiate from the sun. These rays can cause cancer, damage to crops and threat to marine organisms. Chlorine and bromine molecules are responsible for the degradation of the ozone layer. When gases containing these molecules are released into the environment, they cause erosion of short essay on ozone layer ozone layer over time.
The most common halogen gas that damages ozone is chloro-fluoro carbon, also known as CFC. Talking about the efforts being made to save it, the first of all it is necessary that people are aware about the ozone layer and its protection. All people should be aware of the substances and their damage which cause damage to this layer.
There are several easy methods that can protect the ozone layer such as using eco-friendly products, avoiding the use of aerosols and other CFC containing things, promoting plantation etc. It is noteworthy that the ozone layer absorbs ultraviolet rays from about 97 to 99 percent, short essay on ozone layer. To promote its preservation, September 16 th is observed as Short essay on ozone layer Day according to Montreal Protocol. Introduction The ozone molecule is temporary, it absorbs ultraviolet rays and then reverts to an oxygen molecule and a free oxygen atom, this free oxygen atom combines with another oxygen molecule to form an ozone molecule.
Who is Responsible for the Depletion of Ozone Layer? Protecting the ozone layer present in the atmosphere is very important for human life. In the last few decades, studies related to the ozone layer have found that the ozone layer is slowly decaying. Human activities and industries are mainly responsible for the depletion of the ozone layer, which exist in almost all major countries, including the US, China, India and Europe.
Mainly the pollution caused by chemical pollutants released into air damage the ozone layer. The governments of many countries have banned the use of chemicals that damage the ozone short essay on ozone layer, but it is not possible to stop their use completely.
Why the Ozone Layer is Important to us? Ultraviolet radiation is short essay on ozone layer harmful not only for humans, but also for tree plants and animals, it can cause cancer and many dangerous diseases in the organisms.
When is Ozone Day Celebrated? Seeing the importance of the ozone layer, the General Assembly of the United Nations has decided to celebrate the day of 16 th September as International Ozone Day.
Conclusion In order to protect the ozone layer from harm, the people should be educated about it and they should be taught to keep an eye on the industries which are causing pollution. They should have a close concern on this issue and should make personal efforts to protect the environment. The 25th Ozone Day will be held on 16 th September Despite the layer being very thin, it is very important because it absorbs ultraviolet radiation from the sun. If ultraviolet radiation reaches the earth, it damages all kinds of life forms.
Ultraviolet radiation is very harmful not only for humans, but also for trees, plants and animals, it can cause cancer and many dangerous diseases in the organisms.
That is why the ozone layer is very important for life on earth. Who Invented the Ozone Layer? The ozone layer was discovered in by French physicists Charles Fabry and Henri Bussion. When these scientists looked at the spectrum of light coming from the Sun, they found that it had some dark areas.
These areas of the spectrum are called the ultraviolet part. Scientists concluded from this that some element is absorbing the necessary ultraviolet rays, creating a black area in the spectrum and no radiation is visible in the ultraviolet portion. What is Ozone Layer Depletion? Many types of chemicals can damage the ozone layer, short essay on ozone layer, it can also dilute or completely destroy the ozone layer, and these are called free radical catalysts.
The main catalysts include nitric oxide, nitrous oxide, hydroxyl chlorine, and bromine. Chlorine and bromine have been produced in large quantities by the industrial activities of humans.
The huge damage in ozone layer has been done by chlorofluorocarbons and short essay on ozone layer, these chemical are capable of reaching the stratosphere in gaseous form, short essay on ozone layer. After reaching the ozone layer, atoms of chlorine and bromine are separated from their compounds by the effect of ultraviolet rays, and become free radicals; one atom of chlorine and bromine can destroy one million atoms of ozone, nitrous oxide.
Also, the main reason for the thinning of the ozone layer is that there is so much damage to the ozone layer at the southern and north pole of the Earth that there are holes in it. These are called ozone holes. Introduction On 16 th Decemberunder the auspices of the United Nations, 33 countries signed an agreement, called the Montreal Protocol, in Montreal, Canada, to address concerns arising from the ozone hole.
In this conference, it was decided to limit the production and use of chloro-fluoro carbon CFCthe substance that destroys the ozone layer. India also signed this protocol. Its cause and solution is a very complex and serious matter. This topic remains an issue of debate and discussion among international scientists, policy makers and the international community. There is an on-going search on this subject. What is Ozone? Ozone is an atmospheric gas or a type of oxygen.
Oxygen gas O 2 is formed by joining two atoms of oxygen Owhich we use during respiration. A molecule of ozone O 3 is formed by the joining of three oxygen atoms. Its color is light blue and it smells intense, short essay on ozone layer. Ozone gases form a very thin and transparent layer in the stratosphere above. A total of 90 percent of all ozone circulating in the atmosphere is found in the stratosphere. The total percentage of ozone in the atmosphere is very low compared to other gases.
Each million air molecules contain less than ten ozone molecules. Some amount of ozone is also found in the lower atmosphere troposphere. Even though short essay on ozone layer similar, the role of ozone in both places is important. In the stratosphere, it works to protect the earth from harmful ultraviolet radiation.
Ozone acts as harmful contaminants in the troposphere and sometimes produces photochemical splashes. This gas in the troposphere can damage human lungs, fibers and plants even in very small amounts. As a result of human-caused industrial pollution, short essay on ozone layer, the amount of ozone is increasing in the troposphere and in the stratosphere where it is needed; the amount of ozone is decreasing.
Importance of Ozone Layer The ozone layer in the stratosphere acts as a protective shield for the entire planet. It blocks the harmful ultra-violet rays of the Sun in the upper atmosphere, does not allow them to reach the surface of the Earth.
Ultraviolet radiation is extremely harmful to humans, animals and vegetation. Side Effects of Ultraviolet Rays There is a possibility of skin cancer due to ultraviolet rays. Cataract arises in the eyes due to u-v rays and if not treated in time, a person may become blind.
Ultraviolet rays reduce the immunity of humans, short essay on ozone layer, due to which they can become the victim of many infectious diseases. Ultraviolet rays affect the photosynthetic action of trees and plants.
The ultraviolet rays that are called UV-B rays enter the sea and damage marine life. If a pregnant woman comes in contact with them, there may be a chance of damage to the fetus. Conclusion Ozone Layer acts as a protective layer shielding the surface or earth against harmful ultra-violet radiations from the Sun.
Exposure to UV radiations could cause several harmful diseases including skin cancer. Introduction A molecule of ozone or O 3 is formed by joining three molecules of oxygen. Its color is light blue and gives a special kind of intense smell. At an altitude of about 50 kilometers from the surface, the atmosphere is composed of layers of oxygen, short essay on ozone layer, helium, ozone, and hydrogen gases, with the ozone layer acting as a protective shield for the Earth as this ozone layer is protected from harmful ultraviolet rays from the sun on Earth.
These ultraviolet short essay on ozone layer coming from the sun are beyond the endurance of the cells of the human body.
If the ozone layer around the Earth did not have this protective shield, then perhaps the Earth would have been lifeless like other planets. Causes of Ozone Layer Depletion Human actions are the main cause of the increased decay of the ozone layer. Human activities have increased the amount of gases in the atmosphere due to ignorance that are destroying the life-saving ozone layer on Earth. Scientists in an analysis involving the ozone layer have found that chloro-fluoro carbon is predominantly responsible for the dissolution in the ozone layer.
Apart from this, short essay on ozone layer, chemical substances like halogen, methyl chloroform, and carbon tetrachloride are also capable of destroying ozone. We mainly use them in our daily pleasure facilities like air conditioner, refrigerator, foam, paint, plastic etc.
Side Effects of Ozone Layer Depletion Increasing decay of the ozone layer can cause many adverse effects.
For example, harmful ultraviolet rays from the sun can enter the atmosphere on Earth, which are extremely hot and also harmful to tree, plants and animals. These rays in the human body can cause fatal diseases like skin cancer, respiratory disease, ulcers, and obesity.
