Why? A tiger's body can fetch over US$70,000 in Asia, where it's much sought after for its supposed healing powers.
With these huge profits on offer, poachers are sophisticated, well organised criminals, - often using helicopters, night vision equipment, tranquilisers and silencers.
Tigers don't have a chance against this cruel, illegal and devastating trade.
