The tropical rain forests once blanketed the Earth like a wide green belt around the equator. Just a few thousand years ago forests covered 14 percent of the Earth ’s land surface‚ or 5 billion acres. Humans already have destroyed half of this rain forest area‚ with most damage occurring in the last 200 years. Many of the main causes of the rainforest destruction include: logging‚ agriculture-shifted‚ cultivators‚ agricultures-cash‚ crops and cattle‚ ranching‚ fuelwood‚ large dams‚ mining and

Watershed Management and Soil Erosion Forests provide a buffer to filter water and to hold soil in place. They sustain water and soil resources through recycling nutrients. In watersheds where forests are degraded or destroyed‚ minimum flows decrease during the dry season‚ leading to drought‚ while peak floods and soil erosion increase during the wet season. Flooding along the Baram River in Sarawak has increased significantly since logging began‚ the major floods occurring in 1979 and 1981.168
