Deforestation means cutting down trees in large scale. Today it has become a global problem. This problem is increasing day by day. Many wild animals and birds have become extinct due to deforestation.
There are many causes of deforestation. Population explosion is the main cause of deforestation. More people need more food and shelter. For this reason, they are cutting down trees indiscriminately all over the world. Every day the world is losing hundreds of acres of forest. There is a close relation between drought and deforestation. Regular drought is one of the pre symptoms of deforestation. Besides, excess cultivation and soil erosion are other reasons of deforestation.
Deforestation causes serious damage to our lives and environment. It is a great threat to the ecological balance. Carbon-dioxide is increasing worldwide due to deforestation. As a result, the world is becoming warmer day by day. The sea-level is rising and many parts of the world will be engulfed by the sea in recent future. On the other hand, new areas of the world are turning into deserts as a result of deforestation. The birds and animals have to leave their place because of removal of trees. Deforestation also causes serious damage to the soil. Because, trees protect to the soil. The soil makes sediment in the riverbed and causes frequent floods due to the shortage of trees. So, if we destroy trees at random, one day the country will turn into a great desert. All animals and birds will not find any food or shelter. There will no rains. As a result, our agriculture will face a great crisis. The temperature will rise and it will cause greenhouse effect. The country will be unsuitable for living and various natural calamities like flood, drought, storm etc. will visit our country.
Deforestation problem is increasing day by day not only Bangladesh but also all over the world. The united nations has already held several conferences on deforestation. As a nation, we have some responsibilities. We should try to do our duties to prevent deforestation process. So, more plants should be planted to save our environment and lives.
