Deforestation can occur naturally. Forest fires may be caused by lightning or extreme heat in dry weather.
Most forest fires are deliberate.Forests may be damaged or destroyed by acid rain or the deliberate cutting down of trees.Deforestation directly reduces the number of trees. If only one type of tree is felled then this reduces species diversity. The destruction of habitats and food sources reduces the number of animal species in the ecosystem.Animals will migrate to other areas which will result in the biodiversity in other areas increasing.Replanting trees to restore forests only partly solves the problem because usually the forest is repopulated with only a few species of trees.
