In Satkhira, in Bangladesh's southwest, most families have always lived off the land - in Kaliganj, more than half still do. But the climate that made farming possible is now taking it away. Cyclones, creeping salinity and floods are wearing down the soil and the harvests with it, and when the farming income goes, families are left with little to fall back on.

That's when the dangerous options start to look like the only ones - and too many young people are pushed toward drug selling, gambling, or risky journeys abroad that end in trafficking.

What's missing isn't drive or ability. It's a way to earn that the weather can't wash away. And in a country where nearly everyone now owns a mobile phone, the skill to repair one is exactly that - steady, local work that doesn't depend on the land at all.
