( CNN ) -- Dear Girls of the World , . We are under attack . We are denied education . We are bought and sold like cattle . We are threatened and killed for voicing our dreams . We are all suffering . When one girl in the world suffers for being born female , every girl in the world is made vulnerable . Gender-based hate in the most remote corner of the Earth threatens the very core of our dignity . How can any of us be free while our sisters are slaves in this very instant ? To turn a blind eye to a single girl living in sub-human status is to accept that status for each and every one of us . If the girls of the world stay silent , we will protect hate . Only our collective voice can carry our stories far and wide enough to drive out the oppression of girls everywhere . Until the day we all have the opportunity to speak up for ourselves , we have to bear witness for one another . Lift your voice for those who ca n't ! Write an open letter about what girls ' education means to you . - America Ferrera . More : CNN 's `` Girl Rising '' Open letter from Christiane Amanpour : It 's time to power the world .
