As is pointed out in the passage, there is ----.
Although an extension of the worldwide ban on ivory
exports to discourage the illegal killing of African
elephants has been greeted enthusiastically in many
places, the rhinoceroses (rhinos) of southern and eastern
Africa are still paying with their lives for their horns, which
remain prized by the Chinese for their medicinal and
aphrodisiac qualities, and by the Yemenis for making
dagger handles. According to a group, called Traffic, that
monitors the wildlife trade throughout the world, this
illegal business is on the rise. Last month, the group
called for stronger international cooperation along
smuggling routes and for more secure management of
legal horn stocks. For its part, Zimbabwe, where there are
a lot of illegal killings, has taken a very radical decision: it
says it will start dehorning its rhinos. Today only five
species of rhino survive in Africa and Asia. In the past,
especially in the 19th and 20th centuries, they were
slaughtered on a large scale by white hunters. By the
1960s, fewer than 70,000 black rhinos were left in Africa,
and, over the next two decades, illegal hunters wiped out
96% of them. But since 1995, thanks to vigorous
conservation efforts, the number of black rhinos has gone
up again, to around 3,700. The number of white rhinos
has nearly doubled over the same period, to over 14,500.
