Albinism is caused by a genetic mutation. It can he inherited or happen randomly in vertebrate populations. The fact of the matter is that albino animals are less fit and have poorer odds of survival. They lack melanin which protects the skin from the sun, they're more likely to have sunburn and skin cancers, vision and hearing problems, and the lack of hair pigmentation does little to conceal them from predators unless they're in the middle of a snowscape, and in harsh winter climates those all white animals would not absorb heat from the sun as easily as their normally colored herd mates.
Being different or unique does not make them deserving of special protection. The reason that albino animals are rare is that they are poorly equipped for survival compared to their "normal" herdmates.
Albinism is probably not a traits to encourage in the population if we want fittest, most adaptable animals to pass on their genes.
Albino or piebald, if it strikes your fancy, shoot.
