Until those seeds can mature, we’ll have to find alternate means of feeding ourselves. For this, enter the Dutch Organization for Applied Scientific Research. They’re currently exploring the applications for 3-D food printing, using base materials which include algae, insects, and mealworms. At the moment, their research is still in its earliest stages; however, they’ve successfully made a 3-D-printed shortbread cookie from milled mealworms. Of course, this work isn’t being carried out for post-apocalyptic reasons—in fact, they’re looking at 3-D printing as a way of feeding astronauts a varied diet—but it’s easy to see the applications for life after the end.
