| PHOTOGRAPH BY BECKY HALE | | Etsy sells just about everything: Including dead, near threatened species, apparently. During last October alone, researchers monitoring international wildlife trade found more than 500 ads on Etsy and 71 on eBay for products made from bats, including hats and barrettes decorated with the flying mammals. (Etsy declined to comment.) Now the challenge is to discover the scale and impact of the trade, Nat Geo's Wildlife Watch reports. (Online shoppers bought painted woolly bats, like the one above.)
