Although scientists rst found Public concern has been raised about the chemical that became the widely prescribed scientists scouring the worlds tropical rain cancer drug Taxol in the bark of an endangered forests and coral reefs to look for potential species of tree called the Pacic yew, researchers natural chemicals that may end up being have since found a way to manufacture Taxol in useful drugs. While it is true that rainforests the lab, starting with an extract from pine needles in particular are home to an extraordinarily of the much more abundant European yew. In rich array of species of animals and plants, many cases, chemists have also gured out ways many life-saving medicines derived from to make large quantities of rainforest- and reef- natural products have been discovered in temper derived chemicals in the lab (see main text). The cancer drug Taxol originally came from ate climates not much different from our kitchens the bark and needles and backyards.
