FWIW the pig farm industry isn't nearly as bad as it was in that vide now.
It's not much, but the pigs that went through my parents farm were treated very well.
Sow farms, were you saw all the clipping and sows unable to move have had some significant changes.
I wish free range was viable, but there are just to many mouths to feed.
The fact is that livestock agriculture is very inefficient in regards to land-use. If we are going to continue to feed the planet, we need to move away from animal proteins, as a primary source, collectively.
