自从1987年世界人口突破60亿以来,近2年世界人口又增长了大约2.5亿。世界人口的增长速度在70年代曾放慢,但到了80年代又加快了,1989年世界人口总计已经达到了62.34亿。在80年代的最后几年中世界人口还在以每年1.8%的速度增长,成为近年来世界人口增长比率最高的10年。目前,世界每年新增人口超过9000万,这个数字比一个墨西哥国家的人口还要多。
Since the world’s population exceeded 6 billion in 1987, the world population has grown by about 250 million in the past two years. The rate of world population growth slowed in the 1970s, but by the 1980s it accelerated again. In 1989, the world’s population had reached a total of 6.234 billion. In the last few years of the 1980s, the world’s population is still growing at a rate of 1.8% per annum, making it the highest rate of population growth in the world in recent years. At present, the world has more than 90 million new people each year, more than the population of a Mexican country.
