     Elephants and people are in competition for space. In much of Africa, elephants are now put in

national parks. Elephants suffered a serious and steady decrease in numbers in the 1970s. This wa

s the same time when scientists were beginning to learn a great deal about elephants and their behavior.

Studies through the 1980s and into the 1990s showed a lot about their sounds and methods of

communication.

     In Kenya alone, in the 1970s and 1980s, the elephant population decreased from 170,000 to

25,000. The sharp drop in numbers was the result of poachers (偷猎者) illegally killing elephants for

their ivory. The price of ivory went from $3 a pound to $50 to $100 a pound. Africa became very

attractive to poachers. Bull elephants carried the largest tusks (象牙), so they were more often killed.

With males gone and older females killed by poachers as well, there were many young elephants unable

to benefit from the wisdom of the older females and matriarchs, who lead the herds.

     Kenya took a stand, international trade in ivory was officially forbidden, and $3,000,000 worth of

confiscated (没收的) ivory was burned in Kenya. The following year, only 50 elephants were lost to

poachers in Kenya instead of 3,000. But Kenya has the fastest growing human population in the world.

People throughout Africa won't tolerate elephants eating their crops and destroying their livelihoods.

     In South Africa, elephants live behind the fences of national parks. In some parts of Africa, big-game

hunters pay a lot of money to hunt elephants. This keeps their numbers down, and the money goes toward conservation. In Kenya, there were some attempts at birth control to keep the elephant population at

manageable numbers to reduce conflicts with people.

     Faced with a growing human population, elephants are losing the battle for space. It's unlikely, though,

that they will become extinct. They will live in natural parks that bring tourists to Africa as well as India

and other parts of Asia. The money from tourism will help elephants to survive.
