There are some instances where we need to control animals, such as the rampage of feral cats on the native bird populations but I don't support actually killing them. It's not the cat's fault nor the gull's fault they invade parking lots. It's not the House Sparrow's fault nor the coyote's fault they're common. We invite them to live here, we give them the proper conditions to thrive, and by leaving trash out because of utter negligence, we give them a strong motivation to be here in abundance. The best way to get rid of them is to stop recklessly providing the environment they love.
I also hate the practice of hunting animals such as crows and mourning doves. At least they're far more controlled now, so the "sport" doesn't have impact on their populations, but back then, they're responsible for the genocide of the Passenger Pigeons, which were far from being endangered. Many animals became endangered because of them.
As for eating meat, DF, humans are omnivores. Most of us like meat and wouldn't give it up. Other animals eat each other on a daily basis, I don't see why it's bad for us to eat it. Sure, it may raise questions on how we raise animals to eat them, but eh, it's not much different from hunting them in the wild, aside from the appalling conditions the animals are raised on, which also grinds my gears, but not enough to make me stop eating meat.
