How do we build a sustainable tomorrow? That is a key question at the 2025 APEC Meeting in South Korea. With today's youth shaping the future, meet four young change-makers who are turning ideas into action for a sustainable world. From speaking up for biodiversity to engaging in climate research, volunteering across borders and promoting cultural exchange, young people are not waiting for change passively – they are making it happen. As the butterfly emblem of this year's summit symbolizes, even the smallest flutter can spark change – and together, they create a more sustainable and prosperous world.
