Define ozone layer ;The ozone layer is a region of the Earth's atmosphere that contains a high concentration of ozone
molecules
...
It does so by absorbing most of the sun's ultraviolet (UV) radiation that is harmful to living
organisms
...
The ozone layer acts as a shield, preventing the harmful UV radiation from
reaching the Earth's surface
...
This phenomenon is known as the "ozone hole"
and is a serious concern as it can cause an increase in the amount of UV radiation reaching the Earth's surface, which
can have a range of negative effects on human, animal and plant health, as well as materials
...
One of the most successful of these agreements is the Montreal Protocol, which has been
ratified by 197 countries and the European Union
...
It is important to note that, in addition to its
protective role against UV radiation, the ozone layer also plays a role in regulating the Earth's climate
...
However, the majority of the ozone is found in the upper atmosphere, or stratosphere, where it plays
the protective role mentioned before
...
When the ozone layer is
depleted, more ultraviolet (UV) radiation from the sun reaches the Earth's surface, which can lead to an increased risk
of skin cancer and other health problems in humans
...
UV radiation can also have an impact on materials such as plastic and
paint
...
UV radiation can damage the DNA
in cells of living organisms, leading to various health issues
...
It can also have an effect on
weather patterns, causing more severe storms, and changes in the jet stream, which can impact food production and
water resources
...
To mitigate the effects of ozone
depletion, international agreements such as the Montreal Protocol have been implemented, which have been
successful in reducing the production and consumption of ozone-depleting substances, however, the damages are still
ongoing and more effort is needed to fully protect the ozone layerReferenceNoman, A
...
(2023) Ozone layer and it’s
effects on earth The concept of the ozone layer was first proposed by scientists in the late 19th century, and it was
named the "ozone layer" in the early 20th century
