Recently at a talk I gave at a school in Singapore, a child asked me why we couldn't just chop off all the elephants' tusks, because then the poachers would have nothing to kill them for.  It's not the first time someone's raised this idea.  After all, female Asian elephants don't have tusks at all and that doesn't seem to hold them back.  You may have seen the pink tusked elephant doing the rounds on facebook last year, with the suggestion that colouring elephants' tusks bright pink would prevent poachers killing them.  Unfortunately neither of these ideas are the answer to the poaching crisis, and there's a number of reasons why it's not that simple.
