Q: Which country does the article mention taking active measures to discourage child labour?, Context: Concerns have often been raised over the buying public's moral complicity in purchasing products assembled or otherwise manufactured in developing countries with child labour. However, others have raised concerns that boycotting products manufactured through child labour may force these children to turn to more dangerous or strenuous professions, such as prostitution or agriculture. For example, a UNICEF study found that after the Child Labour Deterrence Act was introduced in the US, an estimated 50,000 children were dismissed from their garment industry jobs in Bangladesh, leaving many to resort to jobs such as "stone-crushing, street hustling, and prostitution", jobs that are "more hazardous and exploitative than garment production". The study suggests that boycotts are "blunt instruments with long-term consequences, that can actually harm rather than help the children involved."
