Except that everywhere you say "animal agriculture", the correct term is "Grain agriculture to feed CAFO animals". That same soy and corn land, returned to pasture, would correct almost everything else you mention.
The way to make that happen is not to stop eating meat, that just makes you not a customer and so not a concern.
The functional, non-totalitarian way is for individuals to buy local, grass fed, humanely slaughtered animal foods. That's what will decrease the CAFOS, restore the soil, replenish desertified lands (which are now only kept in crops by oil based fertilizer and irrigation), end the need for antibiotics, reduce the dependance on 3rd world sources (although that might drive them even deeper into poverty), and produce healthier food for everyone.
People like Saladin and Savory are already making this happen, but the religion of veganism just condemns them and ignores the good they are doing. Because feelings. And famous actors.
Except it takes more grain to feed the animal we eat than if we ate the grain we fed the animal and that most of the amazon deforestation has happen because of the grain agriculture needed to feed the animal we eat.
This has nothing to do between you and me. Saladin and Savory have been rebutted for obvious reasons.

Since the only thing I said about grain is to stop using it, I don't know what you are talking about. You might not be considering the benefits of a diverse pasture land.
Saladin and Savory are still producing verifiable results so I guess someone needs to step up the rebutting. They better hurry because thousands of other folks are duplicating the results on their own lands.
It take some land for grazing but the land is already taken to the point we have to deforest large part of tropical forest.
If that were true, that would be a good point.
Good news! It is true! :D
Sad news, it's true!
