There are many medicinal products that come from plants. Herbalists, such as the Chinese, have used herbs to treat various illnesses for centuries. Taxol, which comes from the bark of the Pacific Yew, is used to treat cancer. Digoxin, from the foxglove, is used to treat heart disease. Reserpine, an antihypertensive, comes from the dogbane family. The list goes on. An estimated 25% of a drug prescriptions in the United States are derived from plants.
There is no limit to what can be gained from studying plants, especially those we have not yet found or identified. From a biologist's perspective, there is a real need to protect biodiveristy. Fifty percent of the earth's diversity, including plant diversity, is found on 7% of the earths' surface. This 7% is occupied by tropical rainforests. Fifty-seven percent of all rainforests are found in the neotropics. Unfortunately, the greatest diversity of unstudied plants are found in the rainforests which are being destroyed at a phenomenal rate. Less than 12% of Brazil's Atlantic coastal rain forest is still standing. At the current rate of destruction, all tropical rainforests worldwide will disappear by the year 2175.
