article: From bear testicles and tiger paws to crocodile jaws and snake heads, these are just some of the bizarre animal parts being sold in China's so-called medicine markets. Traditional Chinese Medicine (TCM) claims all manner of ailments including back ache, poor memory and even cancer can be cured by the natural world. It is often believed that  the more endangered the animal is, the greater the healing affect it will have. Such  wisdom is widespread in Guangzhou, where markets stock exotic and rare animals destined for restaurant menus, pharmacists and pet cages. However, a movement of fledgling organisations such as the South China Nature Society, run by student conservationists, is challenging centuries of tradition by trying to change consumer appetites in the country.

With a history of more than 2,000 years, TCM has acquired a list in excess of 1,500 animals, many of which are endangered . Sensitive issue: A tiger penis, which is considered to be a potent aphrodisiac, for sale at Qingping market. China's appetite for endangered wildlife and the 2,000-year practice of Traditional Chinese Medicine is the main catalyst behind the world's third-largest illicit trade . Guangzhou is the richest and most powerful city in southern China, with a keen taste for exotic animals and plants, seen as extreme even in other regions of China. The main reason for this is 2,000-year-old Traditional Chinese Medicine that lists curative qualities in thousands of rare and exotic animals, such as the Sumatran Tiger. The pursuit of these traditions is the driving force behind the $20 billion (£13bn) illegal wildlife network, the worlds third largest elicit trade, surpassed only by arms and drugs. The network activity intensifies in South East Asia home to rich biodiversity, well developed transport infrastructures, high profit margins and lax law enforcement, a haven for wildlife smugglers. Vietnamese authorities recently seized a record haul of smuggled wildlife including two tons of tiger bones, bear paws and gall bladders.

One may of thought that the rise of Guangzhou's economy and subsequent education would have reduced the consumption of endangered animals, but quite the opposite. Rising incomes have allowed more consumers to indulge in exotic foods once considered exclusive delicacies for the rich. The consumption of these endangered animals have now become a symbol of Guangzhou's new wealth. A recent poll taken in Guangzhou found that half the population had eaten wildlife, with snake being named as the favorite of half of those surveyed. A popular saying  has it that people in Guangzhou will eat anything with fours legs accept a chair, anything that flies accept a plane and anything in water except a boat. The greatest defense of animal rights to date was during the SARS outbreak in 2003 when consumption dropped due to public fears about the risk of contracting SARS from wild animals.

Dried snakes at Qingping market. In Traditional Chinese Medicine, snake meat is said to be good for vision and the lower spine . The demand for civet cats decreased so much that 141 farms released 4,000 of the animals into the wild. Bird flu later added to this concerns. In recent years, consumption has recovered. In the latest line of defense stands, the South China Nature Society (SCNS), a young band of four university graduate conservationists. Established in February 2008 by Feng Minghe under the guidance of NGO - Green Eyes China, SCNS faces the mammoth task of challenging centuries of Chinese wisdom in an international hub of exotic wildlife trade. 'Our key objective is to raise awareness and educate consumers on the impact of their consumption. We hope that targeting the next generation will reduce future demand', explains Feng. Raising awareness and educating consumers takes a number of forms. The group organises various workshops and lectures in the local Guangzhou's universities. Each month, they co-ordinate field investigation among the city's live market and record the number of protected species.

Their findings are reported to the authorities and published on the SCNS and Green Eyes websites. On recent visits to the city's notorious live animal markets of Qingping and Huadiwan, SCNS identified a wealth of protected animals from koala bears to crocodiles to great white sharks. Sun, a veteran snake seller at Qingping, said the market sell fewer protected species than before because many animals are near extinction and government checks are tighter. However, he did admit to selling endangered species 'under the table' including Cobra. 'The demand here is so great if I didn't sell it then someone else would, people will always buy,' he said.

'It's 200 Yuan (£21) per kilo, we get it from the wild,' a waiter said. In March, SCNS scored a major victory by protesting outside a Guangzhou restaurant in which was holding a nurse shark in a tiny tank in which it could barely move. Banners reading 'no consuming, no killing' in English and Chinese, caught widespread media coverage from local news channels. In the end, the shark was released to a local marine park. Zheng Ying Yuan, from SCNS said: 'We are still a very young organisation but we are moving in the right direction. But, with 15 million people and 2,000 years of history real changes are going to take time.'
