The problem occurs because the majority of white women have abortions rather than give their child up for adoptions, and the majority of families who want to adopt are anglo. Meanwhile, minority children remain in foster care with no one to adopt them.
Adoptive parents have trouble with interracial adoption because of the controversy that it entails.
However, interracial adoptions are a positive and ethical approach to placing children in loving homes. While many argue that interracial adoptions are wrong, they need only to look in that child's face and consider condemning them to a life of endless foster homes. Surely, then they would agree that an interracial family is much better than no family at all.
