We all know that oxygen is the essential element for a human being and trees are providing oxygen for us. Moreover trees absorb the harmful element of air carbon-die-oxide. But now a days in Bangladesh we can see that people are cutting down trees recklessly for their own live. On the other hand environment pollution is getting higher day by day. As a result the air of Dhaka is getting attacked by this poisonous gas carbon-die-oxide. If this scenario will continue then our future will be in danger. So wake up Bangladesh and save our trees.
