Global warming means increasing heat
of the world day by day. Actually, Global warming is the unusually rapid
increase in Earth’s average surface temperature over the past century primarily
due to the greenhouse gasses released as people burn fossil fuels. There are
many causes behind this problem. Uses of CFCs, carbondi-oxid, cutting down
trees, greenhouse effect and various kinds of pollutants are the main causes
behind this problem. This single problem creates a lot of other problem. It
effects on our personal, social and national life. Everyone should come to
check this problem at any cost.
Some causes of Global Warming
Firstly, Chlorofluorocarbons (CFCs)
are a group of compounds which contain the elements chlorine, fluorine and
carbon. CFCs are also a part of the group of chemicals known as the volatile
organic compounds (VOCs). Generally, CFCs are using some kinds of commercial
and industrial purposes. By using refrigeration equipment, most of the CFCs
come from the atmosphere through the use of aerosols containing them and by
Secondly, Carbon dioxide, or CO2, is
a very common, naturally occurring molecule that contains two oxygen atoms and
one carbon atom. CO2 is called a greenhouse gas (GHG) because as part of
Earth’s atmosphere CO2 traps the energy from the sun and keeps the world at a
livable temperature. Natural and human both types of
sources are making carbon dioxide emissions. Decomposition, ocean release and
respiration are come from natural sources. On the other hand, human
sources come from activities like cement production, deforestation as well as
the burning of fossil fuels like coal, oil and natural gas etc.
Thirdly, cutting down trees or
deforestation is another main reason for global warming.
Deforestation is the permanent
destruction of forests in order to make the land available for other uses.
Trees not only gives us oxygen but also
takes CO2 from us. By cutting down more trees, we can not get oxygen
from trees and it’s effects on any serious problem like global warming.
Fourthly, The greenhouse effect is a
natural process that warms the Earth’s surface. The main reason is when the
Sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to
space and the rest is absorbed and re-radiated by greenhouse gases.
Actually, water vapour, carbon
dioxide, methane, nitrous oxide, ozone and chlorofluorocarbons (CFCs) are
included with greenhouse gases.
Besides theses, there are some
reason for making global warming and theses are come from vehicles, industries,
chemicals and other environment pollution etc,
Some effects of Global Warming
At present global warming is a
dangerous and harmful problem. It is one of the greatest problem in all over
the world. In fact, it has become a problem of our daily life. This single
problem creates a lot of other problem. Some effects are given bellow :
First of all, Increased
precipitation in the form of rain have already been noticed in polar and
sub-polar regions. When global warming are increasing day by
day, it will lead to more evaporation which will cause more rains. Animals and
plants cannot easily adapt to increased rainfall. Plants may die and animals
may migrate to other areas, which can cause entire ecosystem out of balance.
Second of all, the temperature
becomes more warm, it can affect the health of humans and the diseases they are
exposed to. When the rainfall is increaseing, water borne diseases are likely
to spread like malaria. And when the earth will become more warm or heat and as
a result heat waves are likely to increase that can cause a major blow to the
Third of all, As the temperature of
the oceans rises, hurricanes and other storms are likely to become stronger and
also the increase in the global warming, the water in the ocean warms up and it
heats up the surrounding air, creating hurricanes.
Fourth of all, The melting of polar
ice-caps and less water evaporating into the atmosphere are causing increased
sea levels. Quaint coastal towns and cities near the U.S. east coast and Gulf
of Mexico are just a few areas where devastating flood damage is starting to
make its mark in history.
Besides these there are some
negative aspects by global warming like melting of glaciers problem,
agricultural problem, rise of sea levels, heat waves, longer/shorter seasons,
health risks, animal extinction, economic collapse, human extinction etc.
Nowadays, global warming is a
dangerous problem for all over the world. This problem is going out of control
day by day. So everyone should come to check this problem at any cost. There are some solution for
controling global warming.
By driving less you can save not
only fuel but also help to reduce global warming and also by using solar
energy, it can help to control global warming. Planting more trees than cutting
down can help much in reducing global warming then any other method. They gives
us oxygen and takes from us carbon dioxide, during the process of
photosynthesis, which is the main source of global warming. Everyone should
control or tack the necessary steps against greenhouse effect and also control
about fertilizer, waste products of mills and factories, vehicle horns and
smoke etc which are help to increase global warming and everybody should keep
clean our environment like air, water, sound and land etc. Every Govt. should
take the necessary steps against it. New laws should be passed if necessary.
The public should be made conscious of it. Meetings and seminars may be
arranged focusing on the bad effect of it. If we try honestly, this problem
will be disappeared from our world.
In conclusion, global warming is the
major challenge for our global society. There is very little doubt that global
warming will change our climate in the next century. Day by day it is going out
of control which are very alarming. Keeping this problem we can not imagine our
peace and happy life. Everybody wants a good solution for this problem. So
everybody should try to remove this problem with together First, there must be
an international political solution. Second, funding for developing cheap and
clean energy production must be increased, as all economic development is based
on increasing energy usage. We must not pin all our hopes on global politics
and clean energy technology, so we must prepare for the worst and adapt. If
implemented now, a lot of the costs and damage that could be caused by changing
climate can be mitigated.
