In 1990, over 100 countries signed international agreement to make it illegal to buy or sell ivory, which is mainly used for jewelry. Most ivory is made from the tusks(象牙) of African elephants. These tusks are (terrible) valuable—one pair is worth more than three times the income of an African farmer or a factory worker in a year.
Hunting elephants was so profitable from 1979 to 1989 the number of elephants in Africa fell from 1.3 million to 600,000. It was feared that by the year 2020 there would be none (leave). However, thanks the international agreement, there (be) much less illegal hunting since 1990.
But considering (vary) of aspects, it costs a lot of money to preserve elephants. Games wardens (看守人) must be hired to protect them. Land must be set aside for them, and when they destroy a farmer's crops, the farmer must (pay) compensation.(赔偿金)
Zimbabwe and four other African countries say that some of the elephants should be killed legally. This would help keep the population stable, and selling the ivory would help pay for preserving the elephants. But conservationists say that (make) ivory legal to sell would lead to even more illegal hunting. Others say is wrong is to kill elephants because they are sensitive animals that feel emotional pain at the death of other elephants.
