He also did a piece on mealworms. Their thinking is that you can grow enough mealworms in a 20 gal aquarium to provide all of your protein requirements. This vs the acres of land required to grow cows and pigs.
That simply is not true. I have grown meal worms to feed to the chickens... They make a nice treat for them... and make for a serious protein source in the winter. But a 20 gallon aquarium will not grow enough meal worms to provide wholly for a single chicken, not to mention a hoomin.
Meal worms ain't bad, btw... fried, they have a delicious nutty taste.
