Deforestation

Deforestation means cutting down trees at random. This is a problem haunting the whole world. According to the ecologists, for live able environment there should be forest on the 25% land of the total land area. In Bangladesh there is 16% forest of the total land. There are many causes of deforestation. First of all men’s greed is responsible for deforestation. Sometimes because of animosity and enmity man sets fire to the large forest and then deforestation is caused. Sometimes natural calamities damage trees in a large scale. Trees play a pivotal role in maintaining ecological balance. Trees produce oxygen and receive carbon dioxide. In absence of trees carbon dioxide is increasing worldwide. As a result there is global warming. The sea level is rising. Any time in future the earth may be engulfed by seas. So deforestation should be stopped now.
