It's better to grow what grows best in the local environment. You can't grow everything everywhere. Everyone would be really limited in their choice of food if everything was local. Unless we're using some kind of greenhouses, which might eventually be a good idea. But it would require insane amounts of energy. I'm not sure you know what efficiency means. From Wikipedia: "Efficiency is the often measurable ability to avoid wasting materials, energy, efforts, money, and time while performing a task. In a more general sense, it is the ability to do things well, successfully, and without waste." Being less efficient means that you're wasting resources, i.e. using more resources than necessary.
