今天,我们这个星球人口增长之快,使得专家们只能用“人口爆炸”一词来形容。它带来一系列问题,如粮食、住房、教育、就业、环境、能源等等。早在20年前,就有人预言:本世纪最后30年,对人类最严重的挑战不是来自其他方面而恰恰是人类自身,即世界人口的膨胀。全球人口发展趋势世界人口已达50亿,如按目前的增长率(1.7%)继续下去,到2010年,全球人口约达70亿,其中第三世界国家占81%(现在为76%)。到2030年,全球人口将达100亿!比目前翻一番。从世界各地区来看,人口发展将很不平衡。
Today, the population of our planet is growing so fast that experts can only describe it as a “population explosion.” It brings a series of problems, such as food, housing, education, employment, environment, energy and so on. As early as 20 years ago, some people predicted that the most serious challenge to mankind in the last 30 years of this century will come not from other sources but from human beings, namely, the expansion of the world’s population. Global population trends The world’s population has reached 5 billion. As of the current rate of growth (1.7%), the global population will reach 7 billion by 2010, of which the third world countries account for 81% (now 76%). By 2030, the global population will reach 10 billion! Double the current level. From all regions of the world, population development will be very uneven.
