The population of the world has been increasing faster and faster.In 10.000 B.C.There were probably only 10 milion ppl.In A.D.1 there were 300 milion.It took 1750 years for the world population reached 625 milion.In 1850,only 100 years later,the population reached the figure of 1300 milion.In 1950,the figure has more than doubled to reach 2510 milion.In 1985,only 35 years later,there were 4670 milion ppl.In 2000,the world's population was about 6.6 bilion,and by 2010 it's expected to be over 7 bilion.
Does the earth have enough resources to support this many ppl?Diferent sientists give different answer to this question.Some say that there are enough resources to support 8 bilion ppl.Others say that we must limit population growth b/c our resources are limited.Only 10 percent of the earth's land can be used for farming abd another 20% for raising animals.there's limited amount of petroleum.There are also limits to the amouts of iron,silver,gold,and other metals.There's a limit to the water we can use-most of the earth's water is salt water,and most of the fresh water is frozen at the North and South Poles.
Research has repeatedly shown that average Third World woman has more children than she wants.Among the women who don't think thay have too many children,half of them don't want any more,they think they have already had enough.However,although milions of women in the world want to limit the size of their families,they know of no safe way to have fewer children.Safe birth-control methods for family planning are not avaiable to them.It's time governments and international organisations should do something to help them so that the world population growth can desrease intead od continuing to increase.
