Like it or not, around the world many species of animals are seen as tradeable commodities – for things like food, fur, fashion or medicine. Of course we know that historically hunting animals for commercial gain has often been really bad news for the animals concerned. Just stop and think about some of the most recognisable big land mammals – things like tigers, elephants and rhinos – and it’s pretty evident what trade can do to even well-known beasts, pushing many of them to the very brink of extinction.
