Inadequate agroforestry

Insufficient farming of trees
The causes of tree depletion are that trees are being cut down at accelerating rates in order to provide firewood and agricultural land. This can be constructively done under the proper circumstances, but often unsuitable land is being left open for erosion. The basic problem is that human and animal populations are growing at a faster rate than trees can match. Organized efforts to combat the problem have thus far succeeded only in revealing its magnitude.
