21世纪世界的资源和环境

20世纪世界人口从15亿增长到60亿.而经济成长更为快速,自1950年至今已增长4倍.目前世界人口每年增加8000余万人,至2050年将达到90亿,世界经济是否能持续发展以提升或维持现有的生活水准,值得研讨.资源的消长和环境的变迁是具有决定性的两大重要议题.

Resources and Environment of the World in 21st Century

In the 20th century, world population grows from 1. 5 billion to 6 billion along with even faster economic growth which has gone up by four times from 1950 to present. The world population increases at a rate of over 80 million per year, which will reach 9 billion in 2050. But as to whether world economy can be sustainably developed to improve or maintain the present living standard still needs to be studied. The decrease and increase of resources and environmental evolution are two major decisive topics.
