Today there are 6.4 billion people on the earth. By the year 2050 there may be 12.5 billion . There are a lot of people to feed. We need more and more food.
One way to produce more food is growing stronger plants. For thousands of years, farmers 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（遗传的） material. Foods from plants grown in this way are called genetically modified(改变的) foods, 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 becoming blind.
Rich countries produce GM foods because they are easy to grow and bring in more money. 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 may feed people , then hurt them or their children later. But both rich and poor countries are interested in their use, and they are not going to go away. In 2050, we may think differently about them.

“Everything happens for the best,” my mother said whenever things weren’t going my way. “Don’t worry, one day your luck will change.”
Mother was right, as I discovered after I had finished my college education. I had decided to try for a job in radio. One day, I wanted to host(主持) a sports program. I went to Chicago and knocked on the door of every station. But I got turned down every time.
In one station, a kind lady said my problem was that I hadn’t got enough experience. “ Get some work with a small station and work your way up,” she said.
I went back home. I couldn’t get a job there, either. Then my dad told me a businessman had opened a store and needed someone to help him. But again, I didn’t get the job.
I felt really down. “ Your luck will change,” Mom said to me. Dad lent me the car to help me to look for my job. I tried another radio station in Iowa. But the owner, a nice man, told me he had already had someone.
As I left his office, I asked, “How can someone be a sports announcer(播音员) if he can’t get a job in a radio station?”
I was waiting for the lift when I heard the man call. “ What did you mean? Do you know anything about football?” He put me in front of a microphone and asked me to try to imagine that I was giving my opinion on a football game, I succeeded.
On my way home, Mom’s words came back to me, “One day your luck will change, Son. And when it happens, it’ll feel doubly(加倍的) good because of all the hard work you’ve had.” At that moment I knew what just what she meant.
