On the other hand, because the number of people in the world is becoming larger and larger, more and more fresh water is needed. So water shortage becomes a big problem. How can we work out this problem? Scientists have found some ways to turn salt water into fresh water. One important way is to boil （使达到沸点）sea water with high heat until vapor （蒸汽）rises, leaving the salt. In this way, a lot of fresh water can be made quickly.

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 foods （转基因食品）, 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 （准备）, for example, which stops people from 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.
