EXERCISE 3. READING COMPREHENSIVE
A New Home in the Future - by James Stone
Our planet, Earth, is becoming more and more crowded. The world's population will reach 11 billion by 2100*. I think we will need to find a new home in the future. The options are really exciting!
One option is to live on another planet, like Mars or Venus. It's important that the planet has similar gravity to Earth. We need gravity to stay healthy and on the ground! Venus's gravity is similar to Earth's, but Mars's is much lower. Temperature will also be a problem. Mars is very cold, and Venus is very hot. People will need to stay inside all the time. Mars and Venus also don't have enough oxygen for humans.
Another alternative is to inhabit space stations, which could be built near Earth to minimize travel distance [2]. However, space stations are limited in size, restricting movement, and the lack of gravity over prolonged periods could negatively impact human health [2].
