Greenhouse Effect
Introduction: The greenhouse effect is a
dangerous reactive type of effect that influences our nature violently. The greenhouse effect causes natural imbalance. It is dangerous for living creatures on Earth. The
progress of modern science is somewhat responsible for this effect.
Greenhouse effect: The concept of the greenhouse effect evolved from the greenhouse which actually means a glass
house built to protect the from cold air. As these greenhouses are made of
glass, they trap the sunlight and do not let it escape. This trapped sunlight
keeps the interior of the house hot for the tree to prepare food. In the
atmosphere, a similar thing takes place where carbon-di-oxide and carbo-mono-oxide,
which are known as greenhouse 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 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 of rising sea levels.
Causes: There are many causes of the greenhouse effect. The deforestation and burning down of tropical forests, the rapid growth of unplanned industries, overpopulation, all kinds of pollution, an increase in temperature, etc. are the causative factors of the greenhouse effect. Overpopulation 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 the trees of our forests. It causes a 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 amounts of carbon-di-oxide
gas which act as the main agent of the greenhouse effect.
Its dangerous effect: in 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 carbon-di-oxide
gas around the earth. Like the glass houses for the plants in western cold
countries, our atmosphere is guarded by the ozone layer which resists the entrance
of ultraviolet rays from the sun. But recently deforestation, development of
unplanned industries, added number of engine vehicles, etc. are increasing the
amount of carbon-di-oxide gas. As a result, carbon-di-oxide is making holes in
the ozone layer. For this, heat from the sun is directly enters the
earth but has no way to escape. If such a condition goes on for a long time,
the world will be hotter. They will be brought throughout the world. There will
be an increase in violent storms. The rivers will overflow their banks causing
frequent floods. Agriculture, forestry, and fishery will seriously be damaged. Greenhouse
effects make the sea, and many parts of our country will go underwater of the sea.
Way to get rid of: 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 carbon-di-oxide and release oxygen. This
helps to restore ecological balance and restore damage to the ozone layer.
So people should be advised to plant more trees in accordance with their
capability. A campaign for tree plantation should be introduced. Mills and factories
should be set up in a much-planned way. There should be effective drainage
systems to pass 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 the 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.
