Deforestation
Deforestation means the act of cutting down or burning the trees indiscriminately in an area. Nowadays it has become a global problem. According to the ecologists, for liveable environment there should be forest on the 25% land of the total land area. In Bangladesh there is 16% forest of total land. In India there is 13% forest of the total land. Trees produce oxygen and receive carbon dioxide. In absence of trees carbon dioxide is increasing worldwide. There are many causes of deforestation. Among them, population explosion is the main cause of deforestation. People use wood for different purpose. They need shelter, agricultural land, fuel, furniture etc. For all these reasons people cut trees. If people cut down trees at random, one day a number of regions will turn into deserts. There will be no rain and as a result, agriculture will face a great crisis. The temperature will rise and it will cause Green House Effect. The sea level will rise and the low-lying countries of the world will go under water. To get rid of this problem, social awareness can be raised regarding bad effect of deforestation. After all, if we want to save our planet, we must protect our forest.
