En dicho documento se indicaba que de las casi 400.000 especies de plantas vasculares existentes en el planeta (las que tienen raíces, tallos y hojas), solo 6.000 (un 1,5%) han sido cultivadas de forma activa con destino a la producción de alimentos. Además, señalaba que los grandes sistemas de producción agrícola dependen hoy de una lista muy reducida de especies cultivadas, gran parte de ellas vinculada a empresas transnacionales de semillas. De hecho, como indica el citado documento, sólo nueve cultivos (caña de azúcar, maíz, trigo, arroz, patatas, soja, palma de aceite, remolacha azucarera y yuca) representaron en 2013 más de la mitad del consumo mundial medio de calorías diarias en la población humana.
