英语翻译
Today,there are 6 billion people on the earth.By the year 2050 there may be 12.5 bil-
lion.There are a lot of people to feed.We need more food.
One way to produce more is by growing stronger plants.For thousands of years,farm-
ers have made plants better.Every season,they pick the best plants for the next season.It
works very slowly.Since 1983,scientists have been able to change plants more quickly by
changing their genetic material (遗传物质).Foods from plants grown in this way are called
genetically modified food,or GM foods.
By changing the genetic material of a plant,it is possible to make new plants.They
make plants which are strong against plant diseases.They can also help in our diseases.,a
kind of rice is being prepared,for example,which stops people from becoming blind.
Rich countries produce GM foods because they are easy to grow and bring in more mon-
ey.Poor countries are interested in them because they help produce more food.
GM plants are not natural.No one knows how good or bad they are.Making GM foods
is only one way of feeding people in 2050.There are strong feelings against them,because
they are unnatural.They feed people,then hurt them or their children later.But both rich
and poor countries are very interested in their use,and are not going to go away.In 2050,
we may think differently about them.

今天,地球上有六十亿人.到2050年时,可能会有125亿人.将有更多的人需要喂养,将会需要更多的食物.
一方面生产更多的食物需要种植更多的植物,这几千年以来,农民的种植能力已经有了很大的提高.每年,人们选取最好的植物留给下一季节种植.但是这样的种植方式很慢.自从1983年以来,科学家已经找到了可以通过改变遗传物质的方式来使农作物的种植交替转换的更快.食物通过这种方式种植收获来的,叫做转基因食物.
通过改变农作物的的基因,种植出新的农作物已经成为了可能.这里改变可以使农作物抗病.同时,还有一些可以帮助人并治疗疾病,比如说,有一种已经发明出的大米,可以帮助人们预防失明.
转基因植物不是纯天然的植物.现在还没有人能确定这些植物是好是坏,但始终只转基因植物是唯一可以在2050年满足人们对食物需求的方式.有许多人强烈方对这种转基因植物,因为他们觉得这些植物是非天然的.
用他们来给人们吃,转基因植物迟早会对他们或者下一代造成伤害.
但是无论是穷国还是富国都对转基因农作物的用处十分感兴趣,并且不准备放弃研究.到2050年,我们可能会对转基因植物的看法有大大的改变
