There's going to be a lot of insects on the menu in the future.
Crickets are twice as efficient in converting feed to meat as chicken, at least four times more efficient than pigs, and 12 times more efficient than cattle. It's estimated that up to 80 percent
of a cricket is edible and digestible compared with 55 percent for chicken and pigs and
40 percent for cattle. With more of us and pressure on resources, this type of calculation will only get more important.
At the moment, they're working on processing insects into things that don't look like insects (think burgers, for instance) to offset the YEUK! reaction. In tests, people eating insects report that they taste fine but are a bit put off by the appearance.
