This passage tells what some experts think our lives will be like in the future. It begins with a timeline showing predictions from the year 2011 to 2036. Looking further into the future, it predicts that the world’s population will be 11 billion people by the year 2100. As the population grows, more and more people will live in tall buildings that are like small cities. They will drive in cars that steer themselves and fly in hypersonic airplanes that travel at least five times faster than the speed of sound. People may also be able to fly with personal jetpacks and may even live on Mars some day.
