Facts about Rainforests by The Nature Conservancy

• Covering less than 2 percent of the Earth’s total surface area, the world’s rainforests are home to 50 percent of the Earth’s plants and animals.
• Seventy percent of the plants identified by the U.S. National Cancer Institute as useful in the treatment of cancer are found only in rainforests.
• Less than one percent of the tropical rainforest species have been analyzed for their medicinal value.
• Originally, 6 million square miles of tropical rainforest existed worldwide. But as a result of deforestation, only 2.6 million square miles remain.
• At the current rate of tropical forest loss, 5-10 percent of tropical rainforest species will be lost per decade.
• Every second, a slice of rainforest the size of a football field is mowed down. That’s 86,400 football fields of rainforest per day, or over 31 million football fields of rainforest each year.
