Potato chips are very popular in the world. Do you know how they were invented (发明)? In 1853, a native (本土的) American named George Crum made the first potato chips. Crum was a chef (厨师) in an expensive restaurant in Saratoga Springs, New York. One day, a customer (顾客) did not like the French fries. He said they were cut too thick. That day Crum was in a bad mood, so he cut the potatoes really, really thin and he cooked them for a long time until they were very crispy (酥脆的). He wanted to make the customer dislike them. But the customer loved them very much and asked for more.

Other people wanted Crum’s potato chips. Now, there was a new food on the menu—Saratoga chips. Soon Crum opened his own restaurant and made his special chips. It took a long time to make potato chips. People peeled the potatoes by hand. Then in 1920, the automatic (自动的) potato peeler changed everything. Now it was faster and easier to make potato chips. Now potato chips were not a specialty. They were a popular snack food, but only in the north.

A salesman named Herman Lay wanted to sell potato chips in the south. He sold potato chips in bags. His business grew. Today, Americans eat a lot of potato chips every day.

Today there are 6.4 billion people on the earth. By the year 2050 there may be 12.5 billion. There are many 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 (转基因的) foods, or GM foods.

By changing the genetic material of a plant, it is possible to make new plants. Scientists make plants which are strong against plant diseases. They can also help in our diseases; a kind of rice will be grown, 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 uses, and they are not going to go away. In 2050, we may think differently about them.
