Malthus sigue estando equivocado Podemos dar de comer a un mundo con 10.000 millones de habitantes si reducimos la demanda de alimentos

Septiembre 2015

Estamos dejando atrás la era en que la tecnología podía ofrecernos niveles cada vez mayores de consumo, y estamos entrando en otra en que necesitaremos empezar a controlar nuestra demanda. Esto será, sin duda, políticamente y socialmente más difícil que el desarrollo basado en soluciones tecnológicas pero resultará esencial si queremos seguir demostrando que Malthus estaba equivocado sin arruinar nuestro planeta para las próximas generaciones.
