CAN WE SAVE LIFE ON
THIS PLANET EARTH ?
Harmful ultra violet rays are coming from
Sun that are capable of destroying life on the Planet Earth. But the same are
getting reflected back into the space by the Ozone layer in the Earth’s
atmosphere duly not allowing them to enter the surface of the Earth and saving
the life on this planet Earth.
We humans live in the bottom layer of
atmosphere known as Troposphere, which extend up to a height of 10 k m above
mean sea level. Weather changes such as rains, winds, temperature take place in
this layer. The next layer above is called as Stratosphere, which extends up to
50 k m from the ground level. Passenger flights pass through this layer as
there is less turbulence of air and as air density decreases as we go up. Ozone
layer is located at the bottom of stratosphere starting at an altitude of 9
miles and extending up to 21 miles. Ozone layer was discovered in 1913 by
French physicists Henri Buisson and Charles Fabry. An oxygen atom reacts with an oxygen molecule to form ozone
molecule (O3), which contains 3 oxygen atoms. The molecules of ozone are
continuously formed and destroyed in this layer. This ozone layer prevents the
harmful ultraviolet rays from entering the Earth. This protective layer is
under depletion state due to human errors. If it is further destroyed, the life
on earth including human life will be in danger. Ozone holes are being formed
near the poles. The next Earth layer above stratosphere is Mesosphere which
extends up to 85 k m above the planet. The meteorites burn up in this layer.
The layer above this is known as Thermosphere, which extends up to 600 k m
above the planet. Most of the satellites orbit in this layer. The next layer is
Exosphere. This extends about 10000 k m above the planet. This is the upper
most layer of Earth. This is almost half way to the moon.
The common reasons for depletion of Ozone
layer are given below.
Chlorine is considered to be a great
threat to ozone layer. One atom of
chlorine cam destroy 100000 molecules of ozone. Chlorine in chlorofluorocarbons
is emitted by electrical appliances and aerosol cans. Depletion of ozone layer
is also caused by high pollution from the vehicles. Methyl Chloroform used in
industries for chemical processing etc. can also deplete ozone layer. Hydrofluorocarbons.
Deforestation, fire extinguishers, and even certain volcanic activity also
cause depletion of ozone layer. The following measures are needed to protect
the ozone layer to save lofe on Earth.
1. Limit the use of petrol vehicle. Go
for electric vehicles to reduce pollution, use cycles and public transport to
reduce the number of vehicles.
2. Plantation of trees. Oxygen liberated
by trees can assist the formation of ozone. There is need of planting trees in
the open areas of buildings. There is need of planting trees on road sides.
There is need of developing gardens wherever possible.
3. Deforestation should be avoided.
4. Reduce pesticides.
5. Don’t buy products with C F Cs.
6. Avoid use of plastics and non
biodegradable products.
7. Use recycled products.
8. Avoid use of laughing gas.
9. Spread the above information to save
life on this planet Earth.
The increasingly disastrous impacts of the
climate crisis, coupled with inaction to tackle it are sending our planet down
a bleak path towards an increasingly chaotic world which could overwhelm
societies around the globe, reports, Melbourne-based think tank the
Breakthrough National Centre for Climate Restoration. According to them human
civilization may end by 2050. But such things may not happen if the world
governments take care at least from now onwards and societies and citizens come
forward and bring pressure on the governments and political leaders.
Most of the countries are having nuclear
weapons. Any war at this time may have extreme disastrous effect not only on
the warring nations, but also on the entire world. The atmosphere will be very
much polluted and the average temperature will rise, and the sea levels will
rise more than 200 feet resulting in inundation of most of the coastal areas
including some big cities. There is need for stopping such wars by not only by
the United Nations but by all other nations and also by the public of the
concerned countries. Simply speaking, wars at present stage means end of civilization.
I hope that the end of civilization by
2050 as predicted by some experts will not come.
