Deforestation and Its Harmful Effect

Deforestation means cutting down trees indiscriminately from an area. It is one of the much talked global problems which is haunting the whole world. People are cutting down trees to meet up their increasing demand. They are also destroying forests in a large scale to increase their cultivable and residential land. Sometimes they cut down trees and destroy forests in the name of development. Moreover, in many parts of Bangladesh, people are to depend on wood for cooking their food. To make fire, they also cut down trees indiscriminately.

Deforestation disturbs our ecological balance. According to the ecologists, there should be 25% forest land of the total land area of a country. In Bangladesh, there is only 16% forest of the total land. In India, there is only 13% forest of the total land. To meet up the basic needs of food and housing, man is destroying forest without caring. Green patches of land are no more green. New areas of the world are becoming deserts as an immediate effect of deforestation. In absence of trees carbondioxide is increasing worldwide. As a result, there is a global warming. 

We know that trees give us oxygen and take in carbon dioxide. Due to lack of trees, carbon dioxide is increasing worldwide making the world warmer. It is ultimately causing the green house effect. In fact, deforestation has already started to take a heavy revenge on human beings. Various natural disasters like flood, cyclone are showing their appearance frequently. Inadequate number of trees are also causing drought and damaging crops. Today animals and birds living in the forests are on the verge of extinction due to deforestation.

Deforestation has many adverse effects on climate, agriculture and our life. It causes the rise of sea level. Rising sea level brings about flood. Flood brings untold miseries to the people. Deforestation causes river erosion also. River erosion makes many people homeless and shelterless. So we can see that there is an interconnected link and cycle between human beings, animals, and trees. It is deforestation that may cause desertification in many parts of the world, which will pose a serious threat to our living. 

So, we all should be sincere to protect trees and take a firm stand against deforestation. The government should introduce strict law and punish the people who are responsible for deforestation. Alternative use of trees should be found out and tree plantation should be strengthened. Besides, trees that were planted before should be preserved. Thus we can prevent deforestation and ensure a happy and healthy life.
