Four million girls are at risk of child marriage in the next two years because of the coronavirus pandemic.
Global charity World Vision said increasing poverty caused by the loss of livelihoods is likely to drive many families to marry off their daughters early.
But 16-year-old Dola, one of several young activists in Bangladesh, is working to educate parents about the harm that can be done to children if they are married off at a young age.
Dola joined and received training from World Vision. She and her colleagues have stopped more than 600 child marriages in the past two years.
