Outrage over lion's death leads to more money for research

Wildlife officials in Zimbabwe have accused another U.S. doctor with illegally killing a lion with a bow and arrow.

The accusation says Pennsylvania oncologist Jan Casimir Seski killed the lion in April without approval on land where hunting isn't allowed.

This comes after Bloomington, Minn., dentist Walter Palmer was accused of illegally killing a lion named Cecil. Cecil had a radio collar and was part of a research study in a protected area.

That research was conducted by a team led by Professor David MacDonald, director of the Wildlife Conservation Research Unit at the University of Oxford. MacDonald spoke with Heather McElhatton, producer of "A Beautiful World," about his research and the impact of the public outcry over Cecil's death.
