Life in the future will be different from the life today. Between then and now many changes will happen. But what will the changes be? Here are some predictions.
First, work in the future will be different. People won't have enough work to do, and robots will do most work. People will use robots to make cars, do the housework, look after sick people and teach students. People will spend most of their time playing sports and traveling. So people will become stronger and healthier, and they will live to be about 200 years old.
Second, cars will become very small and computers will control their speed. So there will be fewer accidents on the road. Planes will be very popular, and most people would like to take them to travel.
Third, the population（人口） is growing fast. There will be many people in the world and most of them will live longer than people live now. So maybe people will be able to live in the sea, on the moon or on Mars. The earth won't be crowded or noisy. So there will be much space for people to plant trees. There will be less pollution, and the air will become much fresher.
However, water shortage will become one of the most serious problems. If people don't save water now, there will be water wars in 50 years.
