Humanity currently numbers in the 7 billion range. By 2050, the United Nations expects Earth to house just shy of 10 billion human beings. Sounds like a lot, right? It is, but arthropods ("insects, spiders and other arachnids, crustaceans and myriapods") reading along know better: Our tiny companions outnumber us (and all other mammals) by a staggering margin of over 300:1. Though most of the world is already on board with munching insects, much of Western Europe and North America view the concept as madness. Exo, a Brooklyn-based protein bar maker, is trying to change that. For every $3 bar you eat, the protein you consume is "mostly" from (powderized) crickets, to the tune of approximately 40 crickets per bar. I tried one and can confirm: They definitely taste like protein bars, crickets or not. For Exo co-founder Greg Sewitz, the secret to getting people comfortable with eating bugs is disguising it in foods they're already comfortable with.
