Current protein production methods are unsustainable for the growing population.
It takes 2.5kg of feed to make a kilogram of fowl. Global livestock production is expected to increase by 75% by 2030. There’s one major problem–arable land can only increase by 20%.
Overfishing impacts entire ecosystems–8% of annual fishing mass consists of bycatch. Aquaculture consumes 75% of the global fish meal production. We feed fish to fish.
Significant land areas, which could be used for farming or horticulture are used to grow feedstock. More than 30% of global arable land today is already dedicated to animal feed production.
Producing meat requires land that we may not have.
