Crunchy!

One of my favorite topics is speculative agriculture, both science fiction and fantasy. What do people eat? Where does it come from? How is it grown? Answering those questions for a fictional milieu requires a wonderful mix of climate, trade, technology and culture. Sometimes there are real-world sources, like agricultural manuals or cookbooks from a particular time and place (for instance, this wonderful tenth-century agricultural calendar from Cordoba: not only when things happened, but what was important enough to be mentioned).

But this is “science in my fiction,” not “agriculture in my history.” So here’s a really interesting bit of science that if you’re a typical USian or European, you may never have thought about: bugs in space!

Yes, as food.

One of the many challenges that must be overcome if we’re going to leave this planet for extended periods is food. Raising food helps with supply chain problems, and has psychological benefits: would you want to live on preserved food and concentrates for years at a time? But there’s not likely to be room or time for meat animals (maybe fish eventually). So what about insects? They take minimal space and are extremely efficient at converting vegetable matter to protein.

Chinese research has concentrated on silkworms as a source of insect protein, but there are lots of other options, from mealworms to grasshoppers.

Eating insects could help out here on Earth too: raising insects to provide protein is enormously less resource-intensive than beef, pork or even chicken. It’s already an accepted part of the diet in many parts of the world. (And even squeamish Westerners eat plenty of insects in a year.)

Can’t go into space but want to try eating insects yourself? There are plenty of prepared and packaged options.
