All animals being used in animal agriculture and industry suffer, every choice for any products from animals contributes to animal suffering, while every time we do not need those things, there are alternatives without anything from animals for those. But there are addictive substances in food from animal products in them. These are so easy to get past, like within several weeks, and I found the alternatives are not even needed with just having tasty healthy food, that I continue with, and I can say ways I know to have that.
Don’t forget the wildlife issue is multifactorial. You have the impact of animal agriculture on the climate & Earth’s natural ecosystems, ghgs, pollution, land/water/crop/resource use, deforestation, habitat destruction, species extinction, etc (all of which harms and threatens most life on Earth including humans)… but more directly not only do humans wipe out wild animal populations in order to protect “livestock” farming operations (that disturbing irony of “farmers heroically saving the animals from danger so that they can kill them later”…) but then also use that to vindicate the killing of the other animals that become more densely populated as a result of humans’ prior disruption to the balance of the various species within the ecosystem. So it’s literally… killing animals to kill animals to kill animals. E.g. killing the deers in order to kill the foxes/bears in order to kill the cows/pigs/chickens …violence begets violence
