  Hiya!
  Our science is so advanced now that we can grow food pretty much anywhere! Some of the seeds might need to have their DNA changed so that they can survive the harsh conditions on Mars (this is called genetic modification (GM) and it has lots of great uses for the future!). We have already created GM tomatoes that can grow in the desert, so I have total faith that we can grow GM food on Mars.
