The Food CalculationThe Food Calculation
The Grim Math The Shortage Grace calculates that he has only enough food for the trip home if he uses the full fuel load. But the Taumoeba contamination forces him to jettison fuel bays, reducing his fuel. The slower trip will require more time, but he does not have enough food. The Options He can either go home and starve or turn back to save Rocky and die. He chooses the latter. The conflict is a life-or-death decision. The Hope of Taumoeba Rocky suggests that Grace can eat Taumoeba. The microbe is nutritious and non-toxic. This provides a solution. The food conflict is resolved by an unexpected resource.
Surviving on EridSurviving on Erid
The New Diet The Cloned Meat On Erid, Grace cannot eat Eridian food because of heavy metals. The Eridians clone his own cells to provide edible meat. He also eats Taumoeba. The food is bland but sustainable. The Nutritional Challenges Grace suffers from vitamin deficiencies initially, but the Eridians synthesize the necessary supplements. He adapts to his new diet. The Long-Term Survival Grace lives for many years on Erid, growing old in the high gravity. The food supply is sufficient. The conflict of survival is resolved, but at the cost of ever returning to Earth.
