Regarding Animal Spawns..
Wouldn't it be great if the dangerous animal spawns were actual viewable items or blocks that we could choose to destroy to remove them from that area? Bear Spawns could be some unique pile of bones and gore that can be destroyed and even have special drops when destroyed (from their past victims). Or for wolf and bear spawns we could at least "claim" their territory even if it involves a small boss battle.. so when destroying a bear or wolf spawn point, one or more of them appears in few moments and we have to kill him and use a special drop to destroy the bear spawn.. Same for wolves - or if we kill X amount of them, we can use a special drop of say, 5 wolf ears to destroy the spawn.. and 5 Bear Paws to do the same for bears? At least we would have to work for it...
Not sure what to do for neutral creatures or less annoying ones.. But there should be a way for us to make them extinct in specific areas.
Regarding Hunger...
Yeah, I'd like to find a way to make it so instead of dying from going hungry within a day, we can be increasingly weakened unless we have some hearty meals to get our strength back up.. It's much better to make us weaker, cutting trees slower, shooting arrows less accurately.. running slower and mining slower while very hungry than to die so quickly. this aspect of the game could be more balanced.
