7. To carry out the mining activities. To supply various raw materials for industries. Cleaning the natural forests for plantation farming. To earn foreign exchange by exporting forest products

8. Insufficient technical equipment to control forest fire. Failure to involve tribal and local communities in the preservation and augmentation of forest resources. Destruction of the forest due to insects and pest. Illicit trade.

9. Effects of deforestation Soil erosion will take place Sediments will be drained off. Siltation of reservoirs and riverbeds. Increase in the frequency and dimension of floods and droughts

10. Intensification of green house effects. Increase in the destructive force of the storms. Decrease in the supply of raw materials and timber. Marked decrease as fodder to animals.
