I completely understand your standpoint. Animals generally do have a will to survive. But they generally also have no regard for the lives of other animals. An elk or a cougar would happily kill me if they felt so compelled; the elk doing so defensively(they don’t normally accept scare tactics as being good enough, they want to end the threat completely), and the cougar doing so with the intention of eating me for sustenance. I feel no bitterness towards them for that fact, but I share their views. Other animals are outside of my life, unless they become part of my life as threats, as food, or as companions. I would not kill an animal for any reason other than for food or in defence.
The environmental impact is another issue altogether…I disagree that eliminating suffering exacerbates the environmental impact, because it means fewer animals producing less greenhouse gasses. More land use, yes, but the land doesn’t need to be clear-cut and grazing/roaming land can be used in rotation as crop land as well. If all meat farming made the switch to more ethical arrangements, then certainly meat would become less common in grocery stores and much more expensive and I’d probably stop eating it for that reason. Beyond that, the environmental impact of farming meats vs plants is hotly debated and I have not looked into it in great enough detail to decide my own standpoint on it thus far. That’s not because of my love of meat, though. I just haven’t gotten to that point in my assessment of my environmental footprint.
All that said, I do not in any way think that your opinions are wrong or misguided at all. They’re just different from mine.
