Food vs. Feed – When Humans and Animals Compete for Food

Should farm animals play any role at all in a sustainable food system? Only if they are fed in a way that does not jeopardize global food security, researchers say.

One third of the world's farmland is used to produce food for livestock. More and more people are saying that this is inefficient and unsustainable for a growing world population. Animals could eat what humans can't. Waste from the food industry, for example. But it's not that simple. Some options are banned by law, such as kitchen or food waste. And so scientists and startups across Europe are researching the feed of the future. Is it the black soldier fly or duckweed that thrives best on manure? Or do we need to think about the food cycle in a completely different way?
