U.S. population hits 300 million milestone

美国人口突破三亿大关

U.S. census Bureau (美国人口普查局) claimed that America’s population reached 300 million. The U.S. adds 2.8 million people a year, for a growth rate of less than 1 percent. Aging and immigration have pushed America’s population. About 40 percent of the growth comes from immigration. The rest comes from births outnumbering (v. 数目超过) death. It took America 52 years to grow from 100 million in 1915 to 200 million in 1967, but only 39 years to reach 300 million. Only two other countries have bigger populations: China and India. Another contributor to the population’s growth is the fact that people are living longer.http://www.ryedu.net

美国人口突破三亿,对美国人来说喜忧参半。更多的人口意味着劳动力的增长,却会造成更严重的环境污染,并需要更多的自然资源。如何平衡人口增长带来的利弊是世界人口大国都必须重视的问题。
