Disneyland has angered environmentalists by putting shark's fin soup on the menu at its Hong Kong theme park. Conservation bodies WWF and Greenpeace have called on the US entertainment giant to reverse a decision to serve the dish at the Disneyland Hotel when it opens in September. Disneyland - which expects about a third of an estimated 5 million-plus visitors a year to come from the mainland - has rejected the appeals. 'Hong Kong Disneyland takes environmental stewardship very seriously and we are equally sensitive to the local cultures,' said spokeswoman Irene Chan Man-tuen. 'It is customary for Chinese restaurants and five-star hotels to serve shark's fin soup in Hong Kong as the dish is considered an integral part of Chinese banquets. 'At Hong Kong Disneyland, shark's fin soup will only be served to our guests at private functions on special request.' The trade in shark fins is blamed for pushing some species close to extinction and environmentalists have long been fighting to end it. Millions of sharks are killed every year. The fins are often cut off before the sharks are thrown back into the water to die. Of about 400 shark species, 185 are threatened, endangered or vulnerable. Eric Bohm, of the WWF in Hong Kong, said: 'It is our view that a company of the international stature of Disney must take a leadership role in sustainable consumption patterns. 'Disney should be aware that sharks are rapidly approaching the level of over-exploitation.' Martin Baker, of Greenpeace Hong Kong, said: 'How can the same company that produced Finding Nemo - with its message that marine life is under threat - at the same time support a trade that is unsustainable, wasteful and cruel?' Brian Darvell, of the Hong Kong Marine Conservation Society, sent a protest letter to Disney's chief executive officer, Michael Eisner. Professor Darvell wrote: 'There is no doubt that sharks are in trouble. You are overtly and directly contributing to their demise.'
