Did anyone else watch tonight's heart-warming, heart-breaking documentary about pangolins? If you didn't, try and see it. Especially if you're an aficionado of traditional Chinese medicine. Pangolins are scaly anteaters, four species are native to Africa and four to Asia. Their scales are used in Chinese medicine, despite there being no peer-reviewed evidence that they have any clinical value. They are trapped by poachers to supply a multi-million-pound illegal market, and their numbers in the wild are decreasing.
