联合国的数据显示，世界人口将会突破70亿大关。

The world's population will smash through the seven billion barrier on Oct.31, 2011, according to the United Nations. It comes just 12 years since the total reached six billion - with official estimates saying the figure will top eight billion in 2025 and 10 billion before the end of the century.
