The need for diversity in our food supply has been a hot topic lately [1, 2].
Green Revolution agriculture gave us monocultures of a tiny
range of high-calorie crops. The Gene
Revolution of recent decades compounded this with GM versions of the same
crops. Commercial GM plants are overwhelmingly designed to be used in conjunction
with a single herbicide, and many generate a small range of very similar
insecticides.
Paradoxically, the end-products of these staple crops have
diversified. The excuse for developing
them may originally have been feeding the hungry, but large quantities of that
'food' are now diverted into biofuel-production, industrial chemicals and
animal feed.
Those that
do reach the human stomach are highly processed carbohydrates and
chemicals (a.k.a. junk food, or food-like substances). In the dietary desert we now inhabit, our
animals' nutritional needs are better met than ours.
