With food being necessary for all life forms including humans to live, the U.S. Government should consider formally creating a Department of Space Agriculture to coordinate extra-terrestrial farming methods beginning with the moon. Farming should be prioritized for all extra-terrestrial settlements.
It should be possible to create a terrarium on the moon to grow food under glass or under-ground in air-sealed chambers. making space agriculture greatly productive is not a bad idea. Some of the food might even be dehydrated and returned to Earth in compressed form.
