Young people can make a difference by learning about experiences different from our own, using respectful language and working with others on shared problems. International cooperation in health, education and environmental protection shows that challenges do not stop at borders. When we replace stereotypes with understanding, boundaries become bridges rather than walls. Thank you. $
