Now we can understand it. We sustain a conversation and our successful thrillers sustain tension. We are sustained by nourishment. It's about the future, it's about things that grow, it's about stewardship of the earth, and it's suitably vague. Unfortunately, though, we have to puzzle not about the noun yield, but about the noun cuisine.
Cuisine is about cooking, which is about eating and nourishment and health and survival.
Cooking is also about food, which is about growing and transporting and markets and selling and buying and preserving and storing and learned kitchen skills. And in every culture, cooking is about religious festivals and family feasts and daily rituals and courtship. Opening the lid on sustainable cuisine, then, lets loose thousands of pieces of our definitional puzzle, which suddenly looks a lot more complicated. It's time for some help. We have sustainable agriculture, sustainable development, sustainable diets, sustainable cities, sustainable tourism, and now sustainable cuisine.
