Raven: We’re driving them to 
extinction at an unprecedented rate. 
The Intergovernmental Panel on 
Climate Change estimated that 20% to 40% of the species of organisms on 
Earth are likely to go extinct during the present century on the basis 
of global warming alone, without even the other factors coming into it.
HOST:
 Halo, eco-wise viewers, and welcome to Planet Earth: Our Loving Home. 
Today’s program features world-renowned botanist Dr. Peter Raven, who is
 a professor at Washington University, USA and the current president of 
the Missouri Botanical Garden, USA.
Honored as a 『Hero for the 
Planet』 by TIME magazine in 1999 , Dr. Raven has worked for decades to 
conserve the world’s plant and animal species. He is highly respected 
and is a member of 21 different national science academies across the 
globe. Dr. Raven has won many prestigious awards, including the 
International Prize for Biology from the Japanese government and the US 
National Medal of Science, the USA’s highest scientific honor.
Recently,
 he received the 2009 Award for International Scientific Cooperation 
from the Chinese Academy of Sciences for his contributions to Chinese 
botanical research.  
He is also the author of the 
internationally best-selling textbook 『Biology of Plants.』 Vibrant 
biological diversity is a sign of ecological balance and brings 
tremendously benefits to humankind. 
Unfortunately, human 
activities across the globe are rapidly destroying key areas of 
biological richness including rainforests, wetlands, coral reefs and 
grasslands. 
Scientists warn that global biodiversity is in grave
 peril and thus the survival of humanity is at stake. The Lung Ying-tai 
Cultural Foundation’s (龍應台文化基金會) MediaTek lecture series featured a talk
 by Dr. Raven at the National Central Library in Formosa (Taiwan) 
entitled 『Are We Saving Them or Ourselves? Global Action on the Rescue 
of Endangered Biodiversity.』  
We now present excerpts from an 
interview with Dr. Peter Raven, as well as from his talk in Formosa 
(Taiwan) and begin with him addressing some of the reasons why 
biodiversity is so important to our planet.
