Life in the future will be different from life today. But what will the change be?

The population is growing fast. There will be more people in the world and most of them will live longer than people live now.

Computers will be much smaller and more useful and there will be at least one in every home. And computer studies will be one of the important subjects in school then.

People will work fewer hours than they do now and they will have more free time for sports, watching TV and travel. Traveling will be much cheaper and easier. And many more people will go to other countries for holidays.

There will be changes in our food, too. More land will be used for building new towns and houses for all the people. Then there will be less room for cows and sheep, so meat will be more expensive. Maybe no one will eat it every day. Instead they will eat more fruits and vegetables. Maybe people will be healthier.

Work in the future will be different, too. Dangerous and hard work will be done by robots. Because of this, many people will not have enough work to do. This will be a problem.
