FC: The Destruction of Rainforests: Should Deforestation be Prohibited? | By Johnna O'Rourke

1: Rainforests provide us with natural medicines | Indigenous tribes have helped us discover 74 percent of over 120 pharmaceutical drugs we have available today.

2: Rainforests currently supply one-fourth of today's medicines and 70 percent of plants found to have anti-cancer properties are found only in the rainforest.

4: The U.S. National Cancer Institute has identified over 3,000 plants that are active against cancer cells, and 70 percent of these plants are found only in the rainforest.

5: One plant that was found in the rainforest was the Madagascar Periwinkle. Because of this plant, the chance of survival against leukemia was raised from 20 percent to 80 percent. This plant is now extinct due to deforestation.

6: Imagine how many plants have gone extinct that could have saved the lives of thousands from other devastating diseases.

8: Rainforests have the largest diversity of plant and animal life on Earth.

10: Tropical rainforests today only occupy about 7 percent of the Earth's dry land, but they still have over half of all species of animals. | Rainforests once took up over 14 percent of dry land.

11: The Amazon Rainforest is now being taken over by roads, farms, ranches and dams. | More than 20 percent of the Amazon has been permanently destroyed.

12: Scientists have discovered that we are losing about 137 species of plants, animals, and insects every day. That adds up to be about 50,000 species a year.
