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.
