If only we could get over our squeamishness, insects can save the planet, banish hunger, protect the rainforests and reduce the climate catastrophe. At least, that’s what article after article tell us as they sing the praises of feeding our food waste to insects like the larvae of the black soldier fly. Insects can grow 5000-fold in 12 days, producing prodigious quantities of protein in less than 100th the space of soya beans.

There’s just one fly in the ointment, so to speak. Most of the food that insects are fed isn’t waste at all, and after absorbing large amounts of investor cash, some of the biggest companies have gone bust. Dustin Crummett, executive director of the Insect Institute, shared his many reasons for saying that eating insects will not save the planet.

2. If not food or feed, how about “valuable raw materials for various industries”?
