I hate that i cant find anywhere studies that takes the manure used as a fertilizer account in their calculations. Atleast where i live 100% of the manure from the animals is used as a fertilizer on farms and store bought fertilizers are just supplement. Most countries cant produce fertilizer enough for their agricultural need and need to buy it from outside.

I would love some real research wich would be better for the enivorent. Stop meat produsing completelly or scale it down so farms get still some benefits like fertilizer and biogas for the vehicles, but people would not eat food on every meal.
