Edward O. Wilson (Museum of Comparative Zoology, Harvard University, Cambridge, MA, USA):
"Life on earth is largely unexplored in a scientific sense. To date biologists have put scientific names on about 1.4 million species, but we estimate the true number to lie between 10 and 100 million. Most of the existing species are hundreds of thousands to millions of years old and exquisitely adapted to their environment. This little-known biodiversity is a vast source of untapped wealth in the form of food, medicine, timber, petroleum substitutes, soil restorers, and amenities. It is also of deep psychological and scientific value. But as I will show in this lecture, biological wealth is passing through a bottleneck destined to last another fifty years or so, with human-caused extinction now approaching the highest rate since the end of the Mesozoic Era 66 million years ago. How we meet the challenge in the immediate future, by preserving, managing, and using biodiversity, will have major impact on future generations for all time to come."
Vortrag, gehalten am 19. Mai 1993 in der Carl Friedrich von Siemens Stiftung. Der Abend wurde geleitet von Professor Dr. Bert Hölldobler.
