If Earth might have to feed 9 billion people in the coming decades, insects are what’s for dinner.
sustainability fits a pattern. “We think, oh, insects are going to be the silver bullet on protein and nutrition. But what about all this other stuff?” says Bob Martin, director of the Food System Policy Program at the Johns Hopkins School of Public Health. It happened with chicken, he says, and it’s currently happening with aquaculture, as people start building huge offshore fish farms and dousing them with antibiotics.
For example, Aspire Food Group, which produces crickets and cricket flour, sells all its “frass”—cricket poop—to farmers, who use it as a soil amendment. Frass’ percentage amounts of nitrogen, phosphorous, and potassium aren’t much better than readily available fertilizers, says Gabe Mott, Aspire’s cofounder and chief operating officer, but some people think frass amps up plant growth rates. Published work isn’t clear; the body of literature on cricket frass is more of a thorax, apparently.
That day is coming. “We’re putting in the neighborhood of 5,000 or 10,000 crickets in a container, and we’ve got thousands of containers,” Mott says. “We can do research on a scale no lab has ever done.” That translates to processing 1 million crickets a day. To be clear, by some measures, the problem with feeding the world isn’t one of quantity but of distribution. Cut the amount of protein Americans eat, and the land used to produce the plants that feed that meat could instead grow fruits and vegetables, presumably. Americans still eat way
