Answer
We would need breathable air, liquid water and warmth; air is hardest.

Explanation

  • We need breathable air with oxygen for respiration.
  • We need liquid water for drinking and growing food.
  • We need the right temperature to stay warm.
  • A breathable atmosphere is hardest, since Mars's gravity is too weak to hold one.
Air, water and warmth are needed; air is hardest to recreate.
