Yeah, but gameplay trumps realism. The forest is where you start, and with 2.0, it'll be where you mostly have to stay for at least a little bit of time. Like with water, the goal isn't to make it challenging all game, but to make it a challenge in the early game. Not that food or water is any challenge currently unless you're a new player. But that's what they want... something you overcome. So you have less meat in the forest to make it harder in the early game, but then as you progress, it's much easier to get meat for food. No, it isn't realistic. Though unless you're an experienced hunter, you can walk through a forest and never see anything other than a bird or squirrel or similar small animal. Deer might be seen in fields, which the "forest" in the game mostly is, but how often you might see them depends on the time of year and where you are in the country.
Either way, if you want to have a hunger mechanic in the game, you need to have gameplay that makes it at least somewhat challenging, especially in the early game. If it's easy because you can find a dozen animals to kill within a 200 yards radius of your base in the early game, then you might as well remove the hunger mechanic as it's pointless to have. Looking realistic doesn't make it better if you're not playing a true sim game. Even then, if you play any hunting sims, you can spend hours of real time trying to get a single kill because animals don't just walk around waiting to be killed like they do here. That's not something people would want to do in this game.
To be clear, I do like having wolves and bear in the forest. But the numbers of animals you can kill should be low to prevent overabundance of meat.
