This report by US think tank ReThinkX examines the implications of ongoing disruptions to livestock industries. It predicts that current livestock production will be replaced to a large extent by a “Food-as-Software” model, where food can be engineered on the molecular level and produced using “precision fermentation”, e.g. using engineered microorganisms to produce proteins that mimic milk proteins.
As a result of technological advances in fermentation, the report predicts that the number of cows in the United States could halve by 2030. The report also estimates that fermentation-based alternatives to livestock production could be an order of magnitude more efficient in terms of feedstock use, water use, production time and waste production, as well as up to 100 times more efficient in land use.
