Melissa Fay Green answers this question in her book There is No Me Without You:
“Adoption is not the answer to HIV/AIDS in Africa. Adoption rescues few. Yet, adoption illustrates by example: these few once-loved children – who lost their parents to preventable diseases – have been offered a second chance at family life in foreign countries; like young ambassadors, they instruct us. From them, we gain impressions about what their age-mates must be like, the ones living and dying by the millions, without parents, in the cities and villages of Africa. For every orphan turning up in a northern-hemisphere household – winning the spelling bee, winning the cross-country race, joining the Boy Scouts, learning to rollerblade, playing the trumpet or the violin – ten thousand African children remain behind alone.” pp. 24-25
