personally in that respect my opinion is we ought to eat what we kill --Fallen_angel_666
Do they not eat seals that they kill for fur? Is seal even edible? If it's edible and if they just kill seals for fur and discard the rest, that's a terrible waste, yes.
I don't really know how humane you can get when you're killing animals on a large scale. A bullet isn't humane, no, because you can miss and wound the animal without killing it. I don't really know how animals are slaughtered in general, but I imagine never with bullets. I imagine many animals have their necks broken or something of that sort; a broken neck / severed spine is instant death, so far as I know, and probably as painless as you can get while still being efficient.
