What are the three food systems that supply most of our food? What concerns are there that the majority of the world's food calories are supplied by a very small number of plant and animal species?
What will be an ideal response?
?Croplands, rangelands/pastures/feedlots, and ocean fisheries/aquaculture supply most of our food.
Of the tens of thousands of possible plant and animal species, we rely on only a few species for the majority of our food. This leaves us vulnerable to the collapse of our food supply if disease or natural disaster strikes. It also reduces the genetic variation available for overcoming such problems.
