Hello.

Today we sit down with a Colombian drug dealer.

Like any other businessman, he's keen on diversifying,

but not without a touch of serious violence.

Business on the border between Afghanistan and Tajikistan, the fruit and veg trade is doing well,

despite an ongoing insurgency, and somewhere more peaceful and warmer, we go in search of

paradise heading for Costa Rica.

We begin in India. Although reliable figures are hard to come by, campaigners estimate

that hundreds of thousands of children go missing there every year. Many are sold into slavery. Special booths have been set up in some train stations

in the hope of rescuing missing children and deterring traffickers. Online campaigns encourage people to take photos of young street beggars and share

them on social media, but many are never found.

And as Sonia Philiro discovered, parents struggled to protect their sons and daughters.

On the morning that I met Ram Perran, a brickmaker in a remote village in the Northern Indian state of Uttar Pradesh. His family was in the midst of wedding preparations.

The bride was Rambharen's 15-year-old daughter.

The sweet-faced teenager was seated on the floor of their mud hut slathered with

turmeric in a pre-wetting ritual meant to purify the skin. But unlike any

wedding ceremony had been to, this one was devoid of music, dance, even joy. The atmosphere was laden with sadness.

Rumparen hadn't planned to marry his daughter off so young.

He was an illiterate daily wage laborer and like any father he wanted the

best for his children. The legal minimum age to marry in India is 18 for girls and

Rambaran would have liked his daughter to finish her education.
