Scientists striving to save rare pangolins

When social media posts about endangered pangolin being eaten at banquets triggered public fury in China last week, a wildlife protection specialist saw a ray of hope.

"I hope the scandal will become a turning point in our search and rescue of the critically endangered animal," said Zhou Canying, head of the Wildlife Protection Association in Changsha, Hunan province.

Zhou and her team have trekked the mountains of Hunan for more than a year, but not spotted a single pangolin.
