In the future cities, will we have smart buildings and flying cars? Or robots that will pick up our rubbish? What about schools? Will we still travel to school or will we study online from home?
Maybe ... or maybe not, but what we do know is that in the future, cities are going to have more and more people living in them. More than half the world’s people already live in cities, and by 2050, cities will become home to about 6.5 billion people. That’s a lot of people and very little space! More people means that we’re going to have more pollution, traffic and noise. It also means that we’ll need more homes, schools, hospitals, jobs and transport. We’ll need more resources, like water and energy, and more ways to grow food too. Oh, and more parks to play in!
Many cities are already planning for the future. For example, Bristol is a cycling city in England. You can hire (租借) a bike (instead of taking a car or bus) and ride in cycle lanes which are separated from the traffic. In Singapore, people are looking “up” to grow food! To save space, they grow vegetables in lots of layers (层) in special tall buildings, called “vertical farms”. And in Amsterdam in the Netherlands, there are “floating houses” built on water instead of on land!
