Modern and historical uses of trees and forests

Early Tree use People were food gatherers and depended on the forest for all their needs: food, clothing and shelter. They gradually became food growers, clearing a small patch in the forest to grow food. But they continued to depend on forests to meet a lot of their needs.

Today’s Use Even today, people depend on the forest for paper, timber, fuel wood, and medicine.

Medicine  Humans have been depending on the forest to cure them of various ailments.  Even today humans are dependent on the forest for herbs and plants to fight against disease.  Leaves, bark, and other parts of many other trees have medicinal value and are used to make various medicines 

Wood and Paper Trees are used in timber-based industries such as plywood, saw milling, paper and pulp, and particleboard 9lBHuA

Harvesting Selective harvesting  More preferred method of harvesting  Only the largest trees are chosen and smaller trees are planted to replace

Clear cutting:  Requires the use of large machinery that cuts down entire sections of forest.  Soil will be eroded and vegetation will die without trees  Ju9bJwM Ju9bJwM  zKgcOvlM zKgcOvlM
