A Vulnerable Species The smallest bear in the world, an adult male Malayan sun bear is about 4 feet 1. Despite their small size, sun bears can be very dangerous. Malayan sun bears are skillful climbers, aided by long sickle-shaped claws on all four feet.

These extremely long claws — up to six inches — allow the bears to dig for honey and grubs, which they lick up using their long tongues. The bears are omnivores.

Their diet also includes fruits, insects, small mammals, and birds. Malayan sun bears sometimes will damage coconut palm, banana, and cocoa plantations through foraging.

They usually are nocturnal creatures. Causes of Endangerment Many bear species suffer from excessive killing and dramatic habitat loss worldwide. There are eight species of bears in the world: Malayan sun bear, Asiatic black bear, spectacled bear, American black bear, giant panda, sloth bear, polar bear, and brown bear.

The northern brown bears have been eliminated from half their former range. Certain Asian bear species are struggling to survive with 75 percent of their former habitat gone.

Even the polar bear, seemingly isolated in the Arctic, may be threatened by pollutants in the food chain and proposed oil development in denning areas. In addition to leveling the forest, logging roads create convenient access for poachers.

As natural food sources disappear, sun bears are driven by hunger to forage for food on farms and plantations, where they are shot or trapped by angry farmers.

A more concentrated and effective synthetic version of one ingredient of bear gall is widely available and less expensive, but its availability has not reduced the demand for bear gall.

Captive Breeding The Chinese have developed a way to extract bile from the gallbladders of live bears. An estimated 5, bears are now farmed for their bile. Descended from wild-caught individuals, the farm bears are now captive-bred.

This effort is driven more by economics than concern for the animals. More than times the bile can be obtained by milking a live bear than by killing one. Government officials claim that farming has slowed the killing of wild bears, but critics contend it actually promotes the use of bear products and makes them available to more people see also Tigers In Crisis.

All eight species of bears can be found in zoos around the world. Do you think this is the right approach? What do you think of the idea of raising Malayan sun bears on farms to provide bile and gall?

Does this practice help or hinder the survival of wild sun bears? Do you consider farming sun bears to be different from raising domestic animals, such as cattle or chickens?Get the latest international news and world events from Asia, Europe, the Middle East, and more.
