What is the role of natural environments?
1. Biodiversity
Biodiversity is the variety of all life forms on earth—the different plants, animals and micro-organisms, their genes, and the terrestrial, marine and freshwater ecosystems of which they are a part.

2. Food and medicines, resources
-Morphine, a strong painkiller commonly prescribed after surgery or for broken bones, is an extract of the opium poppy.
-In the 1950s, a natural alkaloid called galantamine was extracted from snowdrop bulbs, and this is now used to slow the progression of Alzheimer's disease and mitigate its symptoms, such as memory loss, though it cannot cure the disease. It works by slowing the decline in the transmission of chemical messages in the brain. Proteins from snowdrops are also being investigated as a possible treatment for HIV.
