Why Biodiversity Matters
October 18, 2010
Did you know that the UN declared 2010 the year of biodiversity to draw attention to the rapid rate in which species are disappearing from the planet? And today, officials from around the world are gathered in Japan at a UN summit on biodiversity to talk about the loss of biodiversity in the world – experts say that one-third of amphibians and one-fifth of mammal and planet species are threatened with extinction. This hour, Marty talks with two of the world’s preeminent conservation biologists about why biodiversity matters and how to halt species extinction. Our guests are PETER RAVEN, a botanist and President Emeritus of the Missouri Botanical Garden, and STUART PIMM, a conservation ecologist at Duke University.
