The biologist Edward O. Wilson is widely respected for raising awareness of the importance of biodiversity to the health of an ecosystem. I ran across an interview with him in the new Audubon magazine. Interviewer Boyce Rensberger asked him this significant question:
Q: Do you think the public has grasped the value of whole ecosystems?
A: Apparently only a minority understand this. The last survey that I know of shows that roughly 20 percent of Americans understand what biodiversity is.
Read the full interview here and follow it up with this address and slide show delivered by Wilson at the U.S. Capitol, Washington, DC, April 28, 1998. I found it on the Save America's Forests website when searching on Wilson.
