Industrial processes that keep animals in unnatural conditions throughout their lives (and cause them suffering), has troubled me more and more: there doesn't seem to be much room for respect there.
Exactly what is "unnatural". Even us living in buildings out milking cows with a robot is "unnatural".
Since agriculture is more modern than keeping livestock, I'd say that eating vegetables is more unnatural.
Additionally, while I don't agree with how some livestock are kept for multinationals ( McDo probably), most of the world gives their livestock plenty of room to live ( Europe) and steroids are forbidden here ( unlike in the US)
Source: my dad is a veterinarian and I came across, what you call "industrial processes" ( = farming) daily in my youth. My dad only had 1 client who kept his animals in bad conditions ( long story, but my dad acted correctly with the means possible)
