Dear David,
I'm glad you're interested in life on Mars! Living there is challenging. The gravity is weak, so people need special boots. There's no oxygen, so they must carry tanks. Water is scarce, and temperatures are extreme. However, scientists are working on closed ecosystems to grow food and recycle resources. Maybe one day, humans can colonize Mars. What do you think
Best wishes,
Li Hua
