Last year, thieves broke into a Scottish castle and stole only one thing: a rhino horn, at 1.5 meters
was the longest in the world. In China, pharmaceutical factories have been building up collections of
antiques made from rhino horn, for the sole purposes of smashing them to powder to make the
essential ingredient of many of their medicines. And in Africa, poachers continue to die in the search
for black rhinos.
Recently, conservationists met to plan a campaign to persuade countries where rhino horn is still part
of the traditional medicine to switch substitutes. The biggest threat to the survival of the rhinoceros
is the refusal of certain countries to enforce a ban domestic trading in rhino horn.
The rhino horn is included in many remedies for disorders ranging from fevers to nosebleeds. Horn,
like fingernails, is made of keratin and has no proven medicinal powers. Traditional substitutes, such
as horn from buffalo or antelope, are regarded as second best.
The battle is thought to be winnable. But it may be harder than the battle against the trade in ivory,
for there is a difference between the two commodities. Ivory is a luxury; rhino horn, people believe,
could save the life of their child.
