Around the world millions of children are not getting a proper education because their families are too poor to afford to send them to school. In India, one schoolboy is trying to change that. In the first report in the BBC's Hunger to Learn series, Damian Grammaticas meets Babar Ali, whose remarkable education project is transforming the lives of hundreds of poor children.
At 16 years old, Babar Ali must be the youngest headmaster in the world. He's a teenager who is in charge of teaching hundreds of students in his family's backyard, where he runs classes for poor children from his village.
The story of this young man from Murshidabad in West Bengal is a remarkable tale of the desire to learn amid the direst poverty.
Babar Ali's day starts early. He wakes, pitches in with the household chores, then jumps on an auto-rickshaw which takes him part of the 10km (six mile) ride to the Raj Govinda school. The last couple of kilometres he has to walk.
The school is the best in this part of West Bengal. There are hundreds of students, boys and girls. The classrooms are neat, if bare. But there are desks, chairs, a blackboard, and the teachers are all dedicated and well-qualified.
As the class 12 roll-call is taken, Babar Ali is seated in the middle in the front row. He's a tall, slim, gangly teenager, studious and smart in his blue and white uniform. He takes his notes carefully. He is the model student.
Babar Ali is the first member of his family ever to get a proper education.
"It's not easy for me to come to school because I live so far away," he says, "but the teachers are good and I love learning. And my parents believe I must get the best education possible that's why I am here."
Raj Govinda school is government-run so it is free, all Babar Ali has to pay for is his uniform, his books and the rickshaw ride to get there. But still that means his family has to find around 1,800 rupees a year ($40, £25) to send him to school. In this part of West Bengal that is a lot of money. Many poor families simply can't afford to send their children to school, even when it is free.
Chumki Hajra is one who has never been to school. She is 14 years old and lives in a tiny shack with her grandmother. Their home is simple A-frame supporting a thatched roof next to the rice paddies and coconut palms at the edge of the village. Inside the hut there is just room for a bed and a few possessions.
Every morning, instead of going to school, she scrubs the dishes and cleans the homes of her neighbours. She's done this ever since she was five. For her work she earns just 200 rupees a month ($5, £3). It's not much, but it's money her family desperately needs. And it means that she has to work as a servant everyday in the village.
"My father is handicapped and can't work," Chumki tells me as she scrubs a pot. "We need the money. If I don't work, we can't survive as a family. So I have no choice but to do this job."
But Chumki is now getting an education, thanks to Babar Ali. The 16-year-old has made it his mission to help Chumki and hundreds of other poor children in his village. The minute his lessons are over at Raj Govinda school, Babar Ali doesn't stop to play, he heads off to share what he's learnt with other children from his village.
Forget yourself for others, and others will never forget you.
