   Once you have your greenhouse setup on Mars, making tomatoes should not   
   cost $600 per tomato. I'm not sure which would be more expensive,   
   growing tomatoes on Mars or in Nunavut (not counting the very expensive   
   cost of installing the greenhouse on Mars). In Nunavut, the   
   containerised greenhouses grow plants mostly without human intervention.   
   They just need to have their water tank filled once in a while. One of   
   the difficulties in the Nunavut greenhouses is to give the plants some   
   CO2, that should be easier for the Martian greenhouses.   
      
   Note also, that Martian greenhouses would not only provide produce to   
   the Martian settlers. The greenhouse would make oxygen as a by product,   
   which the settlers would like to have.   
      
   Of course, adapting the greenhouse for Mars and bringing it there will   
   cost many million dollars. But there is a guy named Elon who wants to go   
   live on Mars and we can expect that he will soon have the means to   
   deliver the greenhouse on Mars. And since he has the financial resources   
   subsidise the adaptation work for the Martian environment of the   
   greenhouse, those who build the Nunavut containerised greenhouses, if   
   they join forces with some engineering company, they could probably   
   strike a deal with Elon.

   Musk has more financial resources than any research settlement in   
   Antarctica.

   He wants to go live there.
