Hunting Trade Collection Overexploitation Many animals have suffered for years due to the other products they can provide. Butterflies are commonly used for decoration. The skins of crocodiles, alligators, and snakes are made into shoes and handbags. The shells of Giant sea turtles, used to make tortoiseshell objects, have helped to make them endangered. Millions of birds such as the Lear's Macaw and the Quayaquil Great Green Macaw are killed so that their feathers can be used to make hats and clothing. The elephant is highly prized for its ivory tusks (modified incisors). The rhinoceros is killed for its horn which is made of compacted keratin (same material as human fingernails). The horn which is prized as a medicine and aphrodisiac in the The horns, which are not made of bone but of a compacted mass of hairs, are especially prized by Indians and Chinese, who consider them to be a powerful aphrodisiac. Powdered horn, mixed in a potion, are supposed to cure anything from measles to diptheria. If it is applied externally in a poultice, it is believed to cure boils and chicken pox. Rhinos are protected under the Endangered Species Act and many countries have signed the CITES (Convention on International Trade of Endangered Species) treaty for the banning of importation of rhino horns. Poachers are now at risk at being shot on sight for the riches the rhino horn brings on the black market. Some black market prices included U.S.$4 500 for a single horn and in 1985 the going price in Singapore was U.S.$5 000 for a pound(0.45kg). Luckily, some rhino species, such as the White Rhino, are making a slow comeback. Fur trade Another threat to land mammals is hunting for their skin and fur. Humans have used skins and furs for clothing, rugs, and tents for centuries. But the senseless killing of a large number of mammals for their hides alone is a rather recent occurrence. The Koala bear is widely prized for its valuable skin, and has been hunted ever since Europeans arrived in its homeland. 1-2 million skins were annually exported, attached with labels such as "beaver," "Adelaide chinchilla," "silver-gray possum," and "skunk." The state government itself gave licenses to 10,000 trappers in 1927, knowing full well the precarious position of the Koala bear. Within the next few months, over half a million Koalas were killed. The motivation for declaring open season on the animal came from votes and money. Farm workers and landholders wanted the money from Koala hunting, and the government wanted their votes for the next term.
Baby seals are beaten to death with heacy sticks because they do not want to damage the pure white coats with a bullet hole or a knife. Foxes from Finland are still captured and killed in the wild for their fur. Our desire for fashion could ultimately threaten all species.
