Elephants are used to entertain foreign and domestic tourists in Thailand. As visitors prefer younger animals, the value of a young elephant has soared to around $33 000.
   To meet this demand, smugglers in Myanmar capture and tame wild elephants from the country’s shrinking herds. The young elephants are caught in pit-traps, cruelly beaten to break their spirits and then smuggled across the border. The Tailand authorities have cracked down on this trade with some success over the past two years, but campaigners believe that criminals are now stocking up, ready to transport the animals once again, when restrictions end. Traffic and other campaigners want to see a toughening up of the laws in Thailand. Elephants don’t have to be registered there until they are eight years old, creating an opportunity for smuggling. According to researchers, the extra strain put on by the smuggling of live young elephants could threaten the long-term survival of the species in Myanmar.
