If it strikes you that everything is starting to taste the same wherever you are in the world, you’re by no means alone. This matters: when we lose diversity and foods become endangered, we not only risk the loss of traditional foodways, but also of flavors, smells, and textures that may never be experienced again. And the consolidation of our food has other steep costs, including a lack of resilience in the face of climate change, pests, and parasites. Our food monoculture is a threat to our health―and to the planet.
