To understand why deforestation is such a pressing and urgent issue, forests must first be given credit for what they bring to global ecosystems and the quality of life that all species maintain. Tropical Rainforests presently give a place to call home for 50% - 90% of all organisms, 90% of our relatives, the primates, and 50 million creatures that can live no place but the rich rainforests (World Rainforest Movement 16). Not only are other species at risk, but the human race also benefits from what the trees give. From something as minor as the spices that indulge food to life giving medicines, the rainforests amplify and save lives. According to the World Rainforest Movement, 25% of medicines come from the forests (28). This is a number that does not do justice to all the cures that have yet to be discovered or that have been destroyed. The forests give life, not only to other species, but they help to prolong the human race. The forests have global implications not just on life but on the quality of it. Trees improve the quality of the air that species breath by trapping carbon and other particles produced by pollution. Trees determine rainfall and replenish the atmosphere. As more water gets put back in the atmosphere, clouds form and provide another way to block out the sunï¿½s heat. Trees are what cool and regulates the earthï¿½s climate in conjunction with other such valuable services as preventing erosion, landslides, and making the most infertile soil rich with life. Mother earth has given much responsibility to trees.
