Why albino giraffes do not survive in the wild

Same reason very few albino anything survive in the wild...

They stand out like a sore thumb to preditors (white is a very bad camouflage someplace the never sees snow)... and if they survived the preditors the effects of the sun would take their toll do to lack of pigmentation tp block out the suns harmfull effects.

FACT: White giraffes are extremely rare and are not albininos. In 1938, a giraffe bull was filmed in Kenya that was almost entirely white except for its dark eyes. Since that time, a number of white giraffe bulls have been described (the most recent being spotted by Charles Foley of the Wildlife Conservation Society in 2005). But all of these white giraffes have had some pigmentation, either dark eyes or a faint coat pattern. As a result, no true albino giraffes have ever been discovered.
