Wood has always been a primary forest product for human populations and industrial interests. Since wood is an important structural component of any forest, its removal has immediate implications on forest health. Intensive harvests can lead to severe degradation, even beyond a forests capacity to recover. When the soil has been stripped of its nutrients, farmers move further into the forests in search of new land.

As forests are destroyed in this way, habitiats are removed from the animals living in them, therefore the biodiversity decreases.  Forests also hold a big role in the water cycle as they release back the water that falls on them through transpiration. If trees are removed this may reduce the amount of water vapour  that returns to the air, and may reduce rainfall either locally or in nearby regions which could inevitibly lead to drought. Trees also intercept the rain , lack of interception means that the water will not be slowed down on its journey to the ground. Therefore ...
