¿CUÁL ES la mejor manera de salvar al tigre? Por supuesto, permitir su compraventa y eliminar las restricciones. Hasta China se da cuenta:

China joined the international effort to protect the tiger in 1993. But today there is a growing recognition among many Chinese officials that a policy of prohibition and trade restrictions has not benefited the tiger as much as it has helped poachers and smugglers of tigers and tiger parts.

Conservationists say the worldwide illegal trade in forest products and wildlife is between $10 billion and $12 billion, with more than half of that coming from Asia.

Of the planet’s estimated 5,000 wild tigers, about 75 percent are in India, which, like most nations, believes that commerce and conservation are incompatible. Only a relative handful of tigers — probably a few dozen — can be found in China’s forests. (The United States is home to some 10,000 tigers, owned by zoos and private citizens.) The tiger, in short, is still staring at extinction.

But like forests, animals are renewable resources. If you think of tigers as products, it becomes clear that demand provides opportunity, rather than posing a threat. For instance, there are perhaps 1.5 billion head of cattle and buffalo and 2 billion goats and sheep in the world today. These are among the most exploited of animals, yet they are not in danger of dying out; there is incentive, in these instances, for humans to conserve.

So it can be for the tiger. In pragmatic terms, this is an extremely valuable animal. Given the growing popularity of traditional Chinese medicines, which make use of everything from tiger claws (to treat insomnia) to tiger fat (leprosy and rheumatism), and the prices this kind of harvesting can bring (as much as $20 for claws, and $20,000 for a skin), the tiger can in effect pay for its own survival. A single farmed specimen might fetch as much as $40,000; the retail value of all the tiger products might be three to five times that amount.
