Indonesia has a forest rich in the diversity of population types within it, but over time Indonesia becomes the most endangered forest in the world. The erosion of forests due to illegal logging makes the predominant factor 70-75 percent of the harvested timber harvested illegally. From an economic perspective, illegal logging has reduced state revenues and revenues and estimated losses of the State to 30 trillion annually. On the other hand illegal logging can lead to a lack of water absorption that can lead to floods and landslides.
The impact of deforestation wild of them are:
Loss of soil fertility result in ground absorb sunlight too much so be very dry and arid. until nutrients in the land of volatile. in addition, the rain bias sweeping the remains of nutrisis from the ground. therefore, when the ground already lost a lot of nutrition, then reforestation be difficult thing and cultivation in the land be impossible.
Drop of water resources also be part of the impact of deforestation wild because of the tree very contribute to keep water cycle through the tree roots water absorption then transferred to the leaves, then evaporated and released to the layer of the atmosphere. as tree cut down and the area to be the arid, then close goodbye again that helps land absorb more water, thus finally cause drop of water resources.
Extinction of biodiversity, though tropical forests only area of 6% of the Earth's surface but about 80-90% of the species there's in it. due to illegal logging conducted massive there is about 100 animal species decreased every Ari, biodiversity from various areas lost in the large-scale.
Result in flood due Forest bergungsi as absorbent water can not absorb and save water in a large number when soaker happening.
