When we all become vegetarians we can solve global food security and save the planet

By: Dr. Ir. Sanderine Nonhebel

The production of meat requires a lot of extra resources. For the production of 1 kg of meat you have to feed an animal about 6 kg of wheat. Refraining from meat means that there is 6 times more food (wheat) available for human consumption. Next to this agriculture in itself has a large impact on the environment (deforestation for soybean fields, use of fertilizers and pesticides to increase yields). No meat also means less agriculture and so less environmental impacts. However…a vegetarian meal is not a ’normal’ meal without the meat. Vegetarians use other ingredients in their meals as meat-eaters and these other ingredients also have their environmental impacts. During this lecture we will determine the environmental impact a typical meat menu and a typical vegetarian menu and discuss the rather surprising outcomes.
