The increasing population

At the beining of the20thcentury,the world'spopulation was about 1990,it reached more than five at the beininjg of the 21stcentthe world's population has passed six le say that by the yeay 2010it may be seven means in about 600 years,there will br standing room only on the person will have one half to one square metre of space to live e will be hardly enough space ror angbody else.
你只需看你的手表一分钟，在这段时间内，世界的人口又增加了259人。也许你会认为数量没有那么多。然而，在下一个小时之内，将会有超过15540个婴儿出生在这个世界上。
数量就这样延续着，一个小时接着一个小时。将来的某一天，人们不得不为了370000多张嘴制造更多的食物。将这个数量乘以365。你可以想象在一年之内将会有多少!那么一百年之后会发生什么事情呢?
不断增加的人口数量将会是今天这个世界上最大挑战。世界人口的`数量增加的越来越快。两千年以前，在这个地球上仅仅只有2亿5千万人。在20世纪初，世界人口的数量大约是17亿。在1990年，人口数量已经超过了50亿。现在在21世纪初，人口已经超过了60亿。人们说截止到2010年人口可能达到70亿。那就意味着在大约600年以后，那将会只有立锥之地。每一个人将会只有半平方米到一平方米的地方居住. 对与任何其他人而言将会没有足够的空间了。
