The married couple recently sat down for an interview on CNN show Piers Morgan Tonight to speak about their Real Men Don't Buy Girls campaign, which is helping to stop sex trafficking.
Speaking to Piers Morgan, Kutcher said: 'I don't believe that there's a problem in the world that exists that the solutions didn't exist before the problem. So that's why we're using social media for this campaign.
'It's to actually go right into the heart of where it's taking place. Seventy-six per cent of the transactions for child sex slavery is actually happening online.
'So if we can motivate people while they are online to do something about that, then we can make a dent.'
