Fighting plastic pollution in paradise

Available for over a year

When Kristal Ambrose, who's from the Bahamas, had to hold down a sea turtle's flippers so that plastic could be removed from its intestines, she vowed never to drop plastic again. And her mission quickly grew. She started the Bahamas Plastic Movement to educate young people to try and tackle the problem. They took their fight to the government and managed to persuade them to bring in a ban on single-use plastics. Kristal has been awarded a Goldman Environmental Prize for her work. Pioneering South African doctor Mashudu Tshifularo was once told by a teacher that he was "too stupid" to be a doctor, but he proved her wrong. Last year he performed the first ever middle ear transplant using bones created by a 3D printer to restore a patient's hearing. Outlook's Elna Schütz finds out about his remarkable life.
