We use an autotrophic microorganism called an acetogen. Autotrophic means it can use inorganic carbon to feed itself. Plants are another example of an autotroph. Humans are heterotrophs, meaning we depend on other sources for food.
Is there a possible future where these critters could eventually turn a clean CO2 source into recreationally drinkable fluid?
And yes they could convert CO2 into recreational drinking fluid, and I learned from someone else in this thread that it would be totally legal!
