Nothing less than a call to action can be the focus of this final chapter. This handbook has put forth profound and compelling arguments for rapid transition to sustainable diets. Inaction and excuses cannot be justified; protection of public resources for the common good is of grave importance. Framed by definitions for sustainable diets, issues of dignity, justice, right to food, and governance systems across food systems are discussed. Environmental strategies are illuminated as are approaches to health and well-being. The chapter highlights how education and public engagement, and social policies and food environment are essential. Transformations and food movements are brought to light and their importance in influencing greater shifts. Needed shifts also are underscored in economics and trade policies. Design and measurement mechanisms supplement case studies on food sovereignty. Thus, this concluding chapter provides readers with a comprehensive map of strategies that could dramatically increase sustainability and help to reverse global warming, diet-related non-communicable diseases, and oppression and racism.
