摘要：

The trend in the volume of African ivory coming onto the world market suggests that African elephant populations have declined progressively since at least 1950 and that the rate of decline is presently accelerating. The process is well-advanced in East Africa where few elephants are predicted to survive beyond 1995 outside high-security areas. A similar trend is deduced for Africa as a whole but lagged about 20 years behind that of East Africa. © 1990.
