While most people don't die because starvation, most humans have enough food in their lives to die for other causes/reasons.
The idea is to reduce our dependence of external food, to have enough energy in ourselves, to have a good storage system, so the need for assimilation of food (ethical assimilation) is reduced.
Our final goal is to be completely self-sufficient (no need for something external, we should have all that it is needed). We should have the best efficient (efficiency) energetic system (for all possibles energetic systems), and yet we should be able to increase our expansion and growth until we reach our biggest desirable energetic size.
