Limits on biomass and living space make traditional livestock inaccessible to all but the hyperelite. When they do eat meat, most are happy with resource-efficient vat-grown tissue. Genetically-optimized insects can be almost as economical, and for those among whom "real food" still has a certain cachet, entomophagy has come into fashion.
The most popular brand of edible insects is Fabre's Fabulous Flavors, specially designed so that each species has a unique flavor. There are sweet honeybees, sour grubs, spicy hornets, or the famous savory beetles. They are typically sold out of vending machines, mounted as if in a naturalist's collection, or else in cafes as kebabs.
