AceShowbiz - Hollywood couple Demi Moore and Ashton Kutcher have launched a new campaign against child slavery in earthquake-ravaged Haiti to put a stop to the unethical practice. The pair has teamed up to voice their concerns over the country's 'restavec' system, in which a child is sent to work as a domestic servant for another family as a means of supporting themselves.

Moore and Kutcher claim the slavery prevents youngsters from gaining an education and experiencing their childhood, and have used their Demi & Ashton foundation to sponsor a pledge to encourage members at a United Nations meeting on Wednesday, March 31 to donate to Haiti and call for the restavec system to be banned altogether.

Speaking to website Mashable.com, Kutcher says, "Let's support the Haitian people, but let's support them the right way, and let's support all of them; don't forget about the 300,000 children that are enslaved. It's going to take a lot of loud voices."

Moore adds, "It's about creating the awareness that draws the line of what's acceptable and unacceptable. Any human being enslaved is unacceptable. As long as one is enslaved, then we are all enslaved. It's an atrocity to stand by and let this happen."
