> As factory farms already feed those herds, clearly there's enough grain to feed them.
1. Feed Conversion Ratio is worse for pasture-raised vs. factory farmed so that's not a given - animals being able to move more, waste more calories that aren't being converted to meat
2. You still haven't provided a source for your claim about land usage
We already throw away 30% of our food, and everywhere I look there's fallow land ripe for crops where I live. Rural Canada.
That said, cattle don't need cropland to graze. They just need land that can grow some grass, and space to move around.
Yes there is a higher calorie count for moving around compared to sitting in a box every day. So? It's fairly widely known that we throw away massive amounts of grain due to lack of market.
No, I won't be providing sources or references. I'm the source and reference. You of course can disagree.
If you don't like this path to end factory farming, you may choose another. However I will fight anyone taking my food away. I will at the same time, help those working towards traditional humane farming methods.
Choose which battle you prefer. One with allies, one with enemies. Decide which will get closer to your current goal, even if it doesn't fully align with mine, and others like me.
