15-year-old Global Changemaker Yeon-seo advocates to end cyberbullying.

“Cyberbullying is happening not only in Korea where I live, but also all over the world,” she says.

Yeon-seo mobilises children and young people to “be brave and speak your voice,” because together, their voices “gather and become the power to change the world.”

She hopes her advocacy can provide comfort to victims who feel helpless and anxious that they may experience cyberbullying again.

“Let's all work together to solve cyberbullying. Let’s go for it!”
