What is ozone layer? We can define the Ozone to be a gas which is present naturally in the environment.
Where is Ozone present?- The Ozone layer is present in two layers of the atmosphere.
What is the importance of ozone layer?
The sun radiates a huge variety of radiations such as ultraviolet radiations which are very harmful to the human body. It is the ozone layer which helps to absorb the ultraviolet radiation rays. It also helps to prevent them from reaching the surface of the earth. In this way, they help to save us from harmful rays. The ozone layer which is present naturally in the lower layers of the atmosphere helps in eradicating the pollutants from the surface of the earth.
If there were no ozone layer, the health of every single living being on planet Earth would be threatened. The depletion of the Ozone layer leads to an increased exposure to ultraviolet light, which can cause many health problems. When we are exposed to ultraviolet light, it enhances the risks of cataract development and skin cancer. It is very much possible to treat skin cancer in their early stages. It can, however, be deadly in the advanced stages. A growth in the eye is known as a cataract and they cloud the vision. It can also result in blindness. Enhanced exposure to UV also causes decreased growth of phytoplankton. Phytoplankton is the light-sensitive organism that forms the base of the ocean’s food web and at the same time, it is also responsible for removing much of the carbon dioxide from the atmosphere. Also, a thinning ozone layer would produce lower crop yields. There are many crops like rice which are sensitive to ultraviolet light. Increased UV exposure could make these crops less productive or even kill them. A major population of the earth is dependent on rice as a primary source of food.
The ozone layer is very important for life on earth. It protects us from harmful UV rays that can have serious effects on biodiversity, animals and people’s health, including skin cancer and eye cataract.
The experts have blamed the ozone-layer depletion on man-made chemicals containing chlorine and bromine that are emitted from a number of products and industrial processes.
• The Montreal Protocol in 1987 has been successful in curbing many of the substances that are most destructive to the ozone layer.
• Continued usage of methyl bromide and HCFCs, the banks of chemicals in existing equipment in buildings and the illegal trade in chemicals are areas that require more action. We will not be able to survive without the ozone layer as in the absence of the ozone layer one might suffer from various diseases like skin cancer, eye disorders etc. The harmful UV rays will also destroy the crops and ocean life.

In what ways can I help to protect the ozone layer?
There is a colossal majority of ODS usage in either industrial or commercial purpose as an individual, you can help in the following ways:
- Buy air-conditioning and refrigeration equipment which are not reliant on HCFCs as a refrigerant.
- For existing refrigeration appliances and air-conditioning which are running on CFCs or HCFCs, the refrigerant should be recycled or recovered whenever an overhaul of equipment is to be carried out. You should also consider retrofitting or replacing these types of equipment so that they are able to operate on non-HCFCs refrigerant.
- If your motor vehicle air-conditioners need servicing, it becomes necessary for you to ensure that instead of being vented to the atmosphere the refrigerants are properly recovered and recycled.
- It also becomes necessary for you to check your fire extinguishers to find active ingredients. If “halogenated hydrocarbon” or “halon” is the main ingredient, search for a hazardous waste center where it will be possible for you to recycle it or you can also call your local fire department for instructions on how to dispose of it. Change it with a model that does not have this detrimental ozone-depleting chemical.
- Purchase aerosol products which do not use HCFCs or CFCs as propellants.
- Undertake a regular inspection and maintenance of appliances such as the air-conditioning and refrigeration so as to prevent and minimize refrigerant leakage.
- You should never purchase aerosol products that have chlorofluorocarbons (CFC). Despite the fact that CFCs have been banned in a lot of the applications, you can only make yourself sure by reading the label on all your hairsprays, household chemicals, and deodorants.

Show MoreCase Study of Environmental Conservation of Ozone in Hong Kong The ozone layer present in the stratosphere of the Earth is utmost important to us as it protects us from the exposure of ultraviolet rays which leads to several harmful effects. Without the ozone layer, human will be more prone to skin cancer and eye cataracts. Ultraviolet rays can also cause harm to marine life by reducing the amount of planktons and consequently depreciates the amount of fishes in the ocean. Besides that, the depletion of the ozone layer disrupts the production of crops and forest growth, another two things which are essential to human life and another reason why the ozone layer is substantial to us (Gleason, K., 2008). The Montreal Protocol was created…show more content…
Furthermore, one of the effects of the depletion of ozone layer is that people now are at a higher risk of several sicknesses such as skin diseases, eye problems and destruction of the human’s immune system. Skin cancers, cataract and infectious diseases are mainly resulted from the depletion of ozone not only in Hong Kong but in any other country as well. If we compare the health of the human in the past and present, we can summarize that nowadays, many more new diseases has been discovered and a number of them are caused by the increasing amount of ultraviolet rays human these days are exposed to. Hence, the ozone depletion obviously decreases the population of Hong Kong, due to them getting sicker. In addition, the plants’ and animals’ life cycles may be affected and the food chain will be disrupted in the end. Since the depletion of the ozone brings about many disadvantages to the country itself and the world, ways and plans to avoid the situation from becoming bad to worse should be implemented. Being a part of the Montreal Protocol, Hong Kong must reduce 90% of their HCFC consumption by 2015 according to GovHK (2011), a portal made by the Hong Kong Special Administrative Region Government, since the members of the protocol has decided to fasten the process of eliminating the usage of HCFC in September 2007. Several ways to ensure a decrease
