In many places，agriculture（農(nóng)業(yè)） is developing quickly and people are growing fruit and vegetables for export．This uses a lot of water．Therefore，there could be serious shortages．Some futurologists predict（預(yù)測） that water could be the cause of war if we don't act now．
In future，cars will run on new，clean fuels and they will go very fast．Cars will have computers to control the speed of them and there won't be any accidents．Today，many cars have computers that tell drivers exactly where they are．By 2050，the computer will control the car and drive it to your destination．Also，by 2050，space planes will fly people from Los Angels to Tokyo in just two hours．
