The increasing population
may be the greatest challenge of the world world's population is growing faster and thousang years ago,there only 250millon people on the earth. 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.
你只需看你的手錶一分鐘，在這段時間內，世界的人口又增加了259人。也許你會認為數量沒有那麼多。然而，在下一個小時之內，將會有超過15540個嬰兒出生在這個世界上。
數量就這樣延續著，一個小時接著一個小時。將來的某一天，人們不得不為了370000多張嘴製造更多的食物。將這個數量乘以365。你可以想象在一年之內將會有多少!那麼一百年之後會發生什麼事情呢?
不斷增加的人口數量將會是今天這個世界上最大挑戰。世界人口的`數量增加的越來越快。兩千年以前，在這個地球上僅僅只有2億5千萬人。在20世紀初，世界人口的數量大約是17億。在1990年，人口數量已經超過了50億。現在在21世紀初，人口已經超過了60億。人們說截止到2010年人口可能達到70億。那就意味著在大約600年以後，那將會只有立錐之地。每一個人將會只有半平方米到一平方米的地方居住. 對與任何其他人而言將會沒有足夠的空間了。
