> Why not say he would like to live on Mars? Maybe because it's a dead planet and not very livable.
One could grow plants on Mars. It has close to a 24 hour day-night cycle, and enough sunlight. Growing plants on continental agricultural scales is infeasible with artificial light, but on Earth and Mars, you don't need that. All you need are pressurized greenhouses, and you could have full-blown agriculture on Mars. The industrial processes for creating polymer films from Martian resources on Mars to enable this have already been worked out.
With some genetic engineering, we might not even need the greenhouses.
