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
