Foods that don't need bee pollination are the main foods the world eats because they produce, are more easily planted, store easily, and grow under harder conditions.
There's a reason foods like this are considered sacred in some cultures. Rice, Wheat, Barley, and Maize have all been lifted to a "holy" status in different times, under different cultures, and even in ours.
"Bread." Made from wheat. It's used at communion to remind us of the sacrifice Jesus Christ made. Barley was the symbol of Demeter or Ceres, and where we get the word Cereal. Rice is the most widely grown crop in the world, and rice flour is used to bless with; though I can't think of an example, and Maize is the sacred food of Native Americans and has been for thousands of years.
Even the Lakota, who are hunter-gatherers traditionally, have maize as one of the four sacred foods. To make offerings with. Spring water, Dried meat (Preferably Buffalo), Dried berries (Preferably Chokecherries), and Corn (Maize)...
The simple truth is: If we tried to feed the world using nothing but the foods bees pollinate, we would starve.
