Good answer! It takes ten square meters of plants to recycle just one astronaut's air. That would fill up a small bedroom!
So a crew of three astronauts would need thirty square meters of plantsthat's enough plants to fill a third of the Space Shuttle's cargo bay! Your space station will have to be very big to hold all these plants.
And that's not all you'll need room for. You also need to produce your
own food. How will you do that?
