Brad Pitt is convinced his eldest daughter with Angelina Jolie would certainly have died if she had not been adopted from Africa by the Hollywood couple.
The actor and his partner are parents to six children - three biological kids and three who were adopted from various countries around the world.
The couple adopted Zahara, now six, from an orphanage in Addis Ababa, Ethiopia in 2005 when she was just six months old, and Pitt is convinced the youngster would not have survived if they had not taken her in.
He tells Parade magazine, "I have seen children suffer far beyond what we experience in America - like our oldest daughter. I know she would not be alive (if she had not been adopted). I know what care was available to her, and it was nil. I cannot imagine life without her."
