CAN PEOPLE REALLY LIVE ON MARS?
Li Qiang is interviewing Walker Hiller on the space station about his idea for building a new town called “Wonderworld” on Mars.
1. How can “wonderworld” make sure there is enough oxygen? “Woderworld” will provide a covered area for people to live in with special air supply.
2. How can “ wonderworld” make sure there is enough water? “ Wonderworld” make sure there is enough water by collecting some from under the planet’s surface. After use, this water will be cleaned and recycled so that it can be used as rain to water crops and provide clean drinking water. Everyone will put their dirty water in special tanks and animals will have to go to the toilet in special places. Bacteria will clean this dirty water so it can be used again.

LQ: Is it likely you can find and use water to keep the climate similar to that on the earth? WH: Perhaps. We hope there’s water under the planet’s surface. People will have to collect all the used water so it can be cleaned and recycled as rain. Then it can be used again to water plants and crops and provide clean drinking water.
