回答: 海地据说可能有50万死亡 由 meiyou 于 2010-01-13, 22:04:50:

海地目前的饥饿和赤贫是社会和历史原因造成的,高生育率只是贫穷的结果而已。

PUZZLE #2: OVERPOPULATION

Haiti is a small country, about the size of Maryland. It has between 6 and 6.5 million people. The soil erosion, inability to compete in the international economy, backward agricultural technology and many other factors combine to make this population of 6 to 6.5 million one which Haiti cannot easily support.

The overwhelming portions of the best Haitian lands are used to grow export crops for North America and Europe. This production benefits only a handful of the Haitian elite. Thus, if only the land were returned to the Haitian people and used for local food crops, Haiti would have no difficulty in providing a sound diet for all her people.

Even minimal improvements in agricultural technology (wider use of oxen and plow, for example), or improved understanding of agricultural problems (stronger national help in fighting soil erosion) and the land that is in production of local food crops could be much more productive.

Since hunger is caused by the present social system, it would seem that it is not overpopulation which causes the crisis in Haiti. But this view is shortsighted. A reformed use and understanding of agriculture (both highly unlikely) would make it possible for Haiti to feed its present population and even the expected population into the next century. But, eventually, Haiti will face a population crisis. Certainly by 2025, only 38 years from now, Haiti's present 2.2% growth rate will make Haiti incapable of feeding her people in the best of circumstances.

There are population control programs throughout Haiti. But they simply don't work. Much research shows that moral preaching, sex education, available contraceptive measures and even force do little to reduce populations in very poor nations. This is because people NEED lots of children. They need them for 4 reasons:

As workers in the farm fields.
As old age insurance for parents who have no other security.
Because in a life of low material gratification, raising children is among the few joys and delights one can have.
Because they suffer high children mortality rates, people must have many children so that enough will survive to accomplish 1-2-3.
Sociologists know that only economic development can effectively lower the birthrate, and that economic development--providing old age security, and some level of material comfort, almost invariably lead people to voluntarily limit birth rates. Such a rise in material standard is also accompanied by higher levels of education, which further contributes to voluntary birthrate limits.

Is it really overpopulation which causes Haiti's misery, or is the overpopulation another result of Haiti's misery? It's not a clear case at all. With more humane social planning, Haiti could provide for its people NOW. But what about in a few years? Population is a puzzle.
