Changing our diet would help absorb global food shocks, such as during the Russia-Ukraine conflict
A plant-based diet could improve the resilience of our food system. Moving to such a diet in the European Union (EU) and United Kingdom (UK) alone could replace almost all the production losses from Russia and Ukraine. That’s what an international team of researchers conclude in Nature Food. Leiden…
