Perhaps you are one of the millions of people who viewed the online trailer for a documentary called "The Drop Box". It's about a church leader in South Korea behind a scheme which has seen hundreds of abandoned babies adopted. FRANCE 24 went to meet him at a time when the country is seeing a drastic rise in the number of babies abandoned by their mothers. It's an unintended side effect, ironically, of a change to the adoption law last year to reduce unregistered adoptions of children overseas.
