Rayner's presentation was provocative but his argument was serious. A lot of our dietary protein, he explained in a short item in The Observer, comes from meat, and meat, as we've all been told, is a resource intensive way to eat: It takes something like 5-10 pounds of grain feed to make 1 pound of meat, which is to say nothing of all the water livestock slurp on their way to the slaughterhouse. According to Rayner, who has a book on the future of food production coming out this May ("Greedy Man in a Hungry World"), this makes meat an unsustainable protein source for a growing global population.
Insects, however, are also protein-rich, but unlike beef, they're eco-friendly, and bountiful. Rayner doesn't expect Europeans to be chowing down on whole silkworm pupae anytime soon, but he says there will be subtler ways to turn creepy crawlers into food. He references European Union-funded academic projects that are working on ways to "liberate" protein from insects. Once
fried freed, Rayner argues, this protein can be repackaged as some kind of euphemistically named ingredient (he suggests "NaturesBounty") and shaped into delectables like the-food-formerly-known-as-hamburger. Whether or not insect-based foods will take off is hard to say. They could be the food source of the future. Or, they could be a clever ploy by billionaire entrepreneur Peter Thiel to make his in vitro meat venture look delicious by comparison.
