The problem with our food supply
6.5 billion people
15 crop species and 8 livestock species
Higher food diversity would:
Increase food stability
Increase food biomass
So many other taxa to choose from:
Insects, earthworms, spiders, snails,
small rodents, algae, fungiÉ
And many more as well.
All edible and nutritious, and more efficient than what we currently eat.
