booyou I think its a natural human reaction to want to "rescue" a child in such horrendous circumstances.
However, you would be better of sponsoring a child in Haiti so that a family there has financial support to look after them.
This was my argument with the whole Madonna thing. If you want to "help" a child from a purely selfless position, keep them in their culture but enable a family to look after them. By bringing them over here are you not, in some part, fulfilling your own needs to nurture (and rescue) and therefore being selfish? Also you are assuming that a life in a richer country is a better life than one in a poor country.
Do you honestly believe that the UK is a better, happier, less stressful place for a child to be in the long term? Can you guarantee a child a better quality life at e.g. 12yrs old here than they could be having in a haitian family in a partially rebuilt Haiti?
Inter country adoption is very complex and complicated.
On a practical level, even if the authorities in Haiti wanted children to be adopted overseas (why would they want to lose a generation from a country that has lost so much?), you would need to be an approved adopter before enquiring and, depending where you live, to get approved can take 18months or even up to 2yrs.
There are many orphans in Haiti, there are also many parents who have lost children. Maybe one day these bereaved parents may feel able to adopt a haitian child.
Haiti needs support to find its own solutions.
