ANSWER
The ozone layer is a layer of ozone high up in the Earth's atmosphere stratosphere. In the region between about 10 kilometres and about 50 kilometres above ground, the atmosphere contains more ozone (O3). The exact amount of ozone that can be found varies, the seasonsinfluence it; it is also different in different places on the Earth. [1] This layer can absorb between 93 and 99 per cent of the ultraviolet radiationfrom the sun.[2] This radiation is dangerous to many living organisms on Earth.
The Ozone layer is present in two layers of the atmosphere.
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 crops and ocean life.

Ozone is a gas in the lower level of stratosphere. It is a kind of super-charged oxygen (O3). These CFCs and other similar 'gases when reach to the stratosphere they are broken down by the ultraviolet radiation and as a result they liberate free atoms of chlorine or bromine. ...
Although it represents only a tiny fraction of the atmosphere, ozone is crucial for life on Earth. ... Most ozone resides in the stratosphere (a layer of the atmosphere between 10 and 40 km above us), where it acts as a shield to protect Earth's surface from the sun's harmful ultraviolet radiation.
