The stupid thing is - albino variations occur occasionally in most species and as far as I know they have never become dominant, so could never "weaken the herd." Albino moose and deer are far more likely to be the victims of predation at an early age because they lack the protective coloring of the "normal" young. If they also have some of the other physical defects (poor hearing, poor eyesight) quite common with albinism, then they are even LESS likely to survive to adulthood or breeding age. So even without the hunters running around in the woods, shooting a stunning 150,000 moose a year in Scandinavia, the chances of this moose actually reproducing and having albino offspring (who go on to survive and reproduce) is quite slim. Hunting down this particular moose hardly seems necessary - but then, nor does specifically protecting it.
