„Hunger ist nicht ein Problem von zu wenig produzierter Nahrung“, betonte Professor Robert S. Lawrence von der Johns Hopkins Universität in seinem Referat am 13. Wissenschaftskongress der Stiftung Academia Engelberg. Es sei vielmehr ein Problem von Armut, fehlenden Investitionen in die Landwirtschaft und die Infrastruktur, von Klima und Wetter, Nahrungsverschwendung, Kriegen und unstabilen Märkten.
Weltweit sei die Landwirtschaft für 70 % des totalen Wasserverbrauchs verantwortlich. Weltweit werde das Grundwasser für Bewässerung schneller verbraucht, als es wieder aufgefüllt werden könne. Die Landwirtschaft und der Mensch hätten aber nicht nur Einfluss auf den Wasserverbrauch, sondern auch auf die Biodiversität. So sei die Biodiversität stark zurückgegangen seit sich der Mensch zunehmend in die Natur einmische.
Lawrence sprach einen weiteren wichtigen Aspekt an: Den Energieverbrauch. Er wies darauf hin, dass eine durchschnittliche amerikanische Farm 3kcal fossile Energie benötige um 1 kcal Nahrungsenergie zu produzieren.
