We breathe by inhaling oxygen. Of course this oxygen can not exist in production by itself. Forests are the main source of oxygen in the world, therefore, forests are called the lungs of the world.
Forest destruction in this era is difficult to control, because all aspects of human life depend on the forest to meet the economic needs.
If the forest is not used in a healthy way, the oxygen on earth is of course thinning, in fact the utilization of this forest is not directly proportional to the growth or improvement of the tree. One tree may take decades to grow, but one tree can be logged within minutes.
Of course this gap further exacerbates the destruction of the
forest.
