1 of 5 species of reptiles are at risk of extinction

The future of reptiles is at risk. More than 1 in 5 species of reptiles worldwide, including the fierce king cobra, are threatened with extinction, according to an assessment of thousands of species published Wednesday in the journal Nature. Matt Galloway speaks with Bruce Young, co-author of that study. Scott Gillingwater, lead biologist for Southern Ontario At Risk Reptiles, talks about reptiles in Canada, and we also hear from Mary O'Connor, a professor of zoology at the University of British Columbia.
