A lot of resources go into the production of beef. For example, 20 litres of water is needed to produce just 1 gram of beef. In order to produce food more sustainably to feed an ever-growing population, some alternatives to protein have been suggested. What are some of these alternatives? Do you think they will ever replace meat?
