Paragraph - Global Warming

Global warming means the increase of world's temperature. It has recently been reported that the world's climate is changing significantly. The world temperature is increasing day by day. The greenhouse effect is the most likely cause of this global warming. Carbondioxide is mainly responsible for this global warming. Pollutants such as methane and chlorofluorocarbons etc. also contribute much to the increase of global warming. Deforestation around the world, increasing number of vehicles on the roads, burning down of tropical rainforests, rapid growth of industry, etc. are increasing the amount of carbondioxide. This gas accumulates in the atmosphere and causes temperature to rise. The effects of global warming are serious and dangerous. It has been predicted that by midway through the next century world temperatures may have risen by as much as 4ᴼc. This will greatly reduce mankind's ability to grow food and damage wildlife and wilderness. As a result of global warming, the ice in the polar regions is melting. This may raise the sea level of water and flood coastal areas. So, farmland will one day go under water. The alarming news for Bangladesh is that the lower southern part of the country may one day go under water. At present global warming has become a matter of great concern for the world. Some measures should be taken to prevent global warming. We should plant more trees as trees absorb carbondioxide. We must not burn and destroy our forest land. Old vehicles must not be allowed to ply on the roads. Moreover, vehicles may use CNG gas. The most important thing is to raise public awareness in this regard.
