Food without agriculture

Edible molecules can be directly synthesizedwithout agricultural feedstocks, saving land, water andGHG emissions. Dietary fats made from natural gas feedstock and average U.S. electricity would emit~0.8 gCO2-eq/kcal (and 0 if using atmospheric carbon and renewable electricity) compared to 1-3 gCO2-eq/kcal from agricultural fat production.
