Biodiversity and Human Health
The role of biodiversity on human health can not be stressed enough. Essentially all food and most human medicines are derived from biological organisms. However, we are helping to eliminate thousands of species each year in what is called the sixth great extinction. We are loosing crop genetic diversity that helps keep our food system healthy, and we may be, or likely are losing new medicines and biologically-based technological innovations through the loss of species.
