Question

Why can't we grow plants on Mars?

Answer 1

Answer:

Under Martian gravity, the soil can hold more water than on Earth, and water and nutrients within the soil would drain away more slowly. Some conditions would make it difficult for plants to grow on Mars. ... Also, the Martian atmosphere is not as thick as Earth's atmosphere, which keeps our planet warm.
