The international save the children union is a group of people who want to help kids around the world who need help. It's like a superhero team, but instead of fighting bad guys they're fighting things that make kids sick or sad, like hunger, poverty, and sickness.
The team is made up of adults who want to make the world a better place for kids. They work together to raise money and awareness about the problems that kids face in different parts of the world. They also work to find ways to solve those problems, like building schools or providing medicine to sick kids.
The international save the children union is a really important group because they help kids who might not have any other way of getting help. They want every kid to have a happy and healthy life, no matter where they live or what their circumstances are. And that's a pretty super thing to do!
