I understand but I think that’s more of a technicality.

Ok but your decision is nonsensical it’s like saying that because you’re breathing carbon dioxide and there’s too much carbon dioxide in the air you shouldn’t breath air out in the open but should instead stay inside a bubble that filters out the carbon.

Then tell me what’s not supported.

And finally you can probably make the calculation on the amount of fertilizer a cow will produce over a given period of time and how much that will improve your crop yield versus the nutrition you’d get from simply eating it. And you can further perform the calculation on the carbon cost of transporting the manure versus creating it in a factory
