Introduction Greenhouse effect is a dangerous reactive type of effect
that influences our nature violently. Greenhouse effect causes natural
imbalance. It is dangerous for living creature on earth. The progress of
modern science is somewhat responsible for this effect. Greenhouse
effect: The concept of greenhouse effect evolved from the greenhouse
which actually means a glass house built to protect trees from cold air.
As these green houses are made of glass they trap the sunlight and do
not let it escape. This trapped sunlight keeps the interior of the house
for the tree to prepare food. In the atmosphere, a similar thing takes
place where carbon dioxide and carbon monoxide, which are known as the
green house gases, cause the greenhouse effect. Due to various reasons
these two gases are increasing In the air. The two gases decay the ozone
layer and allow more of the sunlight to enter the atmosphere but
leaving no way for it to escape. This Increased heat is not only causing
an imbalance in our ecology, but also melting the ice of the polar
region, as a result raising the sea-level. Causes: There are many causes
of greenhouse effects. The deforestation and burning down of the
tropical forests, rapid growth of unplanned industries, overpopulation,
pollution, increase of temperature etc. arc the causative factors of
greenhouse effect. Over population is a problem for any country. They
need additional things for their survival. They need to cut down trees
to build their houses, furniture, boats, fuel etc. Thus we are losing
our forests and trees. It causes natural imbalance. The use of various
chemicals in mills and factories has a great effect on our environment.
Besides these mills and factories emit black smoke and pollute the air.
Thus deforestation, the rapid growth of unplanned industries, the use of
chlorofluorocarbons (CFCS) in packaging and manufacturing chemical
products etc. produce huge amount of carbon dioxide gas which acts as
the main agent of greenhouse effect. Its dangerous effect: In the recent
years It has been noticed that the world temperatures are increasing
day by day. This increase in global warming is caused by the increased
amount of carbonic-oxide gas around the earth. Like the glass houses for
the plants in the western cold countries, our atmosphere is guarded by
ozone layer which resists the entrance of ultra violet ray from the sun.
But recently deforestation, development of unplanned industries, added
numbers of engine vehicles etc. are increasing the amount of
carbonic-oxide gas. As a result, carbonic-oxide is making hole in the
ozone layer. For this, heat from the sun is directly entering into the
earth hut getting no way to escape. If such condition goes on for a long
time, the world would be hotter. There will be drought throughout the
world. There will be an increase in violent storm. The rivers will
overflow their banks causing frequent floods. Agriculture, forestry and
fishery will seriously be damaged. Greenhouse effects make the climate
warm. So, the ice in the arctic region would be melting. Many islands,
cities near the sea. Many parts of our country will go under water of
the sea. Remedy: To prevent the dangerous effects of greenhouse
necessary steps should be taken immediately. People should not be
allowed to cut off trees, because trees play an important role in
fighting the greenhouse effect. Trees take carbonyl-oxide and release
oxygen. This helps to restore ecological balance and restore the damage
in the ozone layer. But unfortunately, due to deforestation trees are
not enough at the moment in our planet to create a balance in the
environment. So people should be advised to plant more trees in
accordance with their capability. Campaign for tree plantation should be
introduced. Mills and factories should be set up in a very planned way.
There should be effective drainage systems to pass away waste materials
and poisonous chemicals. Conclusion: The climate of the world is
undergoing a significant change. The temperatures are increasing day by
day on account of greenhouse effect. Unless these causes of the
greenhouse effect are controlled many creatures on earth will be on the
verge of extinction. So measures should be taken to prevent such an
undesirable situation.
