Because we have too many religion-addled fools for parents who are dead set against teaching science to their children if that science conflicts with their religious myths. That's why.
Aha, just what I suspected!
Damn those parents anyway! Who do they think they are, anyway? Who do they think those children belong to?
I'm really surprised that all those addled fools have sense enough to reproduce! Maybe they'll die off or get eaten by predators or something.
More funding is needed, that's for sure.
