 Rutgers University's Department of Human Ecology at the School of Environmental and Biological Sciences's associate professor, Pamela McElwee, who is one of Chapter 5's co-authors, said that "dietary change"—"particularly in developed countries of the West"—such as reducing "excess" consumption of "high-greenhouse-gas-emissions diets" high in lamb and cattle consumption is a "win-win" because it addresses both climate crisis and health problems at the same time.McElwee said that food security is a major concern as there is potential for "food crises developing "on several continents at once," according to "The Times".Climate warming speeds up the "rate of soil loss and land degradation" which heightens the risk of "severe food shortages."
