Since George W. Bush became president, 57 species have been declared endangered, usually as a result of lawsuits. That's fewer than under any president since the Endangered Species Act was signed by Nixon in 1973. Now Bush administration officials are reviewing proposed changes to the way the ESA is enforced.
On today's Underreported, we'll look at which species are threatened and which are thriving these days....and how the proposed changes to the ESA could affect the survival of endangered species. Leonard talks to Stuart Pimm, a conservation biologist and Professor of Conservation Ecology at Duke University.
