Environmental pollution traps heat waves surrounding the earth gradually 15 and thus produces Greenhouse effects. There are multiple causes of this calamity. The destruction and burning down of the forests, traffic jam in the streets, rapid growth of and the use of detergents, etc, cause Greenhouse effects. Besides, overpopulation, air pollution, water pollution and increase of temperature are also important causes for it. As our country is overpopulated, we need more houses to live in. Similar is the case with many other countries. For housing they need to cut trees. This causes natural imbalance. Even the unplanned setting up of mills and factories pollute the air. Carbon dioxide is mainly responsible for causing Greenhouse effects. This carbon dioxide is produced by burning fossil. burning wood as fuel in a large scale. This increases surface temperature from 1.5° to 5.5° and results in Greenhouse effects. Bangladesh is one of the most overpopulated countries in the world. The number of population is very high in comparison with her land area. Her density of population per square kilometre is about 1,500. Climatologists predict that in the middle of this century temperature may rise by 4°C. This can disastrously reduce food production, severely damage wild life and cause the rise of sea levels. Consequently, it will flood coastal areas damaging farmland and houses. It may take a serious turn making Bangladesh go under water.

Title: Greenhouse effects

There are various causes of Greenhouse effects like deforestation, various types of smoke, artificial chemical and various types of pollution. Overpopulation is another severe cause of these effects. Carbon di-oxide is mainly responsible for this Greenhouse effect which is produced by burning various types of fuel in a large scale. As Bangladesh is a densely populated country, climatologists predict that it will face many problems caused by Greenhouse effects which include reduction in food production, damage of wildlife and rise of the sea levels and southern part of the country may go under water.
