Producing meat pollutes and requires a lot of space and resources (water, grains . . . ). To protect the planet, we must therefore find new sources of protein. One of the solutions is to replace, at least partially, meat by insects.
The problem is that insects, as a food, are rejected by Europeans and North Americans as inedible, dirty and disgusting. Yet, 2 billion humans (in Asia, Africa, South America) eat them regularly. The most commonly consumed in the world are beetles such as beetles, mainly in larval form (like the mealworm), lepidopterans (caterpillars) and hymenopterans (bees, wasps and ants).
