Mostly concerned with health reasons.
It's sad when the animals die of course but that's nature, the circle of life.
There are animals out there( Lions, Tigers and bears oh my!) that'd happily eat any of us people without thinking twice, so I fail to see why it's wrong to eat animals, as long as they're not tortured into death or throughout their life time.
That said I don't agree with animal cruelty, and I think it's sad the bad condition's farm animals are kept in and how they're later put down.
