Efforts to save the manatees of the Amazon

The manatees of the Amazon region have the familiar nostrils and sad eyes of their Florida relatives but they are smaller - and they're endangered. Ongoing hunting and the growing effects of climate change have contributed to their dropping numbers over the years but a number of local efforts are underway to bring them back. Host Carolyn Beeler speaks with Miriam Marmontel, an Amazonian manatee expert and senior researcher with the Mamiraua Institute for Sustainable Development in Tefe, in the Brazilian Amazon.
