let us consider what we can do for thefood problem
the simple way to increase food production ,one might suppose ,is to bring more land into farmland and put more people to work on it.
but it is proved in some developing countries that this will bring some problems.it will quickly make some soil poorer and destroy forest growth furture more ,the people there will always find they need more people to work on this land to produce more food .
duringg the past 20years,some deveoping countries thve increased a lot more farmland in their countries,but their populations in meantime have grown faster,therefore they are faarther than before.and their food increase has been gained at cost of using up rich lands.many of the lands have become poor lands and are producing less food now.
meanwhile ,farming in the develope countries has produced more food through improved technology .since 1940,farmland has been reduced 7 percent in the united states but cereal production has jumped 60 percent .the increase in the corn output ,thanks to hybrid corn ,has been even greater.
the secret is scientific ways,of course,and compared to the developing countries ,the poputions in developed countries have increased just a little larger than twenty years ago .
on the whole ,world population today in increasing at the speed higher than ever before .every year the population in two percent larger ,so that the 6000million people on the earth today will present another 120million mouths to be fed by the time next year.it is a fearsome thought that this time tomorrow there will be added to this world population some 360 thousand persons.
what can we do about the increase population ,or the lack of food to feed such a large ,increasing population that is a very important problem before everyone on the earth ,young or old,men or women.
就让我们想我们可以为thefood问题
的简单方法增加粮食产量,有人可能会想要把更多的土地变为农田,把更多的人去完成它.
但在一些发展中国家,证明了一些问题,这将带来必速速成一些土壤贫穷毁坏森林未来发展更,那里的人总能找到他们需要更多的人工作在这片土地上,制造更多的食物.
在过去的20年中,一些发展国家增加了许多农场在他们的国家,但他们的人口增长要快其间,于是,他们faarther比before.与食物增加成本价取得了丰富lands.许多使用的土地和土地变得贫穷减少食物生产了.
与此同时,农业生产发展国家更多的食物,通过完善的技术约定场所会面.因为1940年,农田已降低7%在美国,谷类产量增加了60%,在玉米产量,由于杂交玉米,甚至更大.
秘诀就是科学的途径,当然,对照发展中国家,poputions在开发中国家,增加只是有点比二十年前的事了.
总的来说,世界人口增长速度今天在每一处比以往任何时候都要每年2%的更大的人口,今天地球上的人们6000million会出现另一个120million嘴喂养从第二年.这是一个可怕的认为明天的这个时候,将会有加入这个世界人口约360万的人.
我们能做些什么关于增加人口、或缺乏食物给这大,人口增长吗?那是一个非常重要的问题,然后大家才在地球上,年轻的或年老的,男人和女人
