Sujon: Hello hasib, how are you? Hasib: I am fine and what about you? Why do you look so worried? Sujon: I am also fine. I am not worried at all. But I am thinking why MANY people of our country are cutting TREES indiscriminately. What is the reason BEHIND this? Hasib: Oh, yes! Everyday many people are cutting trees on a large scale. They are doing so mainly for fuel, furniture, etc. Sujon: Yes, but these people may not know the bad effects of deforestation. What is your idea about deforestation? Hasib: You are right. However, I think deforestation is very harmful to us. Sujon: Yes, the importance of trees is too many to describe. Once there were a lot of trees in our country, but people are destroying our forests day by day. Hasib: Yes, indeed! If we destroy trees at random, the temperature will rise and one day the country will turn into a great desert. Sujon: You are right. Deforestation disturbs our ecological balance seriously in nature. Hasib: Absolutely. Due to deforestation, carbondioxide, the main culprit of nature, increases on a large scale in atmosphere and cause greenhouse effect. Sujon: You are correct. It is greenhouse effect for which global warming happens in the world. Hasib: Exactly! And as a result of global warming ice starts melting in the sea, which ultimately increases the water level of sea. Sujon: Yes. This increase of sea water level is a great threat as it may submerge the coastal areas of many places in the world including Bangladesh. Hasib: You are absolutely right. We have ALREADY experienced lots of natural disasters like Tsunami, Ayla, Kohinur etc. Sujon: Yes, indeed. And in other places of the world, flood visits frequently. Thank you very much for your excellent idea about deforestation. Hasib: You are most welcome. Good bye. See you again.
