Research has shown that logging of trees creates deserts and this is due to a number of causes, also, it leads to some effects. Firstly, because of larger population, people need land clearance. Thus, it declines the amount of trees. Moreover, as a result of more food needed, a large number of trees are cut to increase the expansion of farming areas. However, the decline of trees rise the possibility of land. Also, the number of deserts increase result in lack of grazing area for farm animals. Finally, the increasing of deserts make a lack of area for human inhabitation.
