What will our life be like in 100 years? No one can truly know the answer, but we are sure that it will be very different from the life today. My brother David makes some predictions. Here are some of his ideas.
First, people will have less work to do. People will spend most of their time playing sports and traveling. So people will become stronger and healthier, and they will live longer as well.
Second, computers will control the cars and people don't need to drive. So there will be fewer and fewer traffic accidents on the road. Planes will be very popular, and most people would like to take a plane for their trips. As for robots, they'll be very popular with human beings. Every family will have a robot. Robots will do dangerous and heavy work for people.
Third, people will be able to live in the sea, on the moon or on other planets. The earth won't be crowded or noisy any more. So there will be much place for people to plant trees. There will be less pollution, and the air will become much fresher.
Finally, water shortage (短缺) will become one of the most serious problems. If we don't save water now, people will start wars for water in 100 years.
