Agrobiodiversity and Feeding the World: More of the Same Will Result in More of the Same por Herforth, Anna, Johns, Timothy, Creed-Kanashiro, Hilary M., Jones, Andrew D., Khoury, Colin K., Lang, Timothy, Maundu, Patrick, Powell, Bronwen, Reyes García, Victoria

“…Food system sustainability is threatened by soil erosion, fertilizer pollution, water overuse, tropical forest degradation, climate change, and genetic uniformity in agricultural production. Meanwhile, access by all to healthy, diverse, and safe food choices is far from realized, and food-related noncommunicable diseases such as type 2 diabetes, obesity, and heart disease are now epidemics as the world increasingly partakes in a diet high in sugar, fat, and salt. …”
