Life in the 2050s will be different from that in the present time，because many changes will take place．What will the changes be?

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

Computers will be much smaller and more useful，and there will be at least one in every home．And computer study will be one of the important subjects in schools．

People will work fewer hours，but have more free time for sports，watching TV and traveling．Traveling will be much cheaper and easier．And many people will go to other countries for a holiday．

There will be changes in our food，too．Because more and more people know the importance of healthy diet，maybe no one will eat meat．They will eat more vegetables and fruit，too．Dangerous and hard work will be done by robots．Because of this，many people won't have enough work to do．This will be a problem．
