For the last 20 years, insects have been touted as the next big thing in food, because they have a lot of protein and would be reasonable to produce at scale. And people who don't understand agriculture think land only suitable for animal husbandry could magically support amber waves of grain if we stopped eating steers.
But are insects too icky? Perhaps to people who have never seen animals slaughtered but have killed an insect. However, people who claim to know a lot about animal welfare and food, vegetarians, are okay with insects
. Zoologically, they are correct, insects are not animals the way they think of animals any more than sponges are, though all share the broad Animalia kingdom.
