Climate and Food Production: Insects vs. Livestock>

“For crickets fed diets comparable in quality to the feed given to
conventional Western livestock, diet conversion efficiency is about
twice as high as for broiler chicks and pigs, four times higher than
sheep and nearly six times higher than steers, DeFoliart reports.
Insects’ quick reproduction and high fecundity makes them look even
more environmentally attractive. For the crickets, DeFoliart has
calculated, this translates into “a true food conversion efficiency
close to 20 times better than that of beef.”

Gracer likens these differences to gas-guzzling versus gas-sipping
vehicles: “Cows and pigs are the SUVs of the food world. And
bugs-they’re the Priuses, maybe even bicycles.”>
