Paragraph On Global Warming

Global Warming
Global warming means gradual increase in the world’s temperature caused by green house gases. The main green house gas is carbon dioxide and others include nitrous oxide, chlorofluorocarbon (CFC), methane etc.Now a days global warming has made the environmentalists think about the dreadful consequences. It has become a threat to all living beings on earth. Global warming is due to greenhouse effect. It is the gradual warming of the air because of heat being trapped on earth. This is happening because of environmental pollution. We are destroying our tropical rain forests, growing industries and mills-factories, using CFC gas. Thus, we are polluting our environment. By the destruction and burning down our forests, the amounts of carbon dioxide are increasing. The increased amounts of carbon dioxide around the earth have made a layer in space. The sun rays are coming through the layer but the heat can not pass through the layer. This is why the heat is being trapped on earth and making our globe warmer. As a result of this, the temperatures of the world are increasing day by day. The weather pattern is changing. The alarming news is that the polar ice caps are melting and this might cause the flooding of huge areas of the globe. Bangladesh also can not escape the paws of this enemy. The lower southern part of the country may go under water one day. We should prevent the pollution of the environment and save our only living place.
