Marine biologist and ocean climate advocate Carissa Cabrera joins us to talk about ocean conservation, youth engagement, and the importance of storytelling in driving global action. Drawing a powerful link between the work of the Universal Postal Union and the ocean movement, Carissa highlights how multilateral frameworks must be paired with bottom-up, community-driven accountability to truly deliver results.
 
Speaking as a juror for the 2025 International Letter-Writing Competition, Carissa reflects on the voices of young people who imagined themselves as the ocean, calling on humanity to care. Their words, she says, reveal not only deep empathy but a shared determination to act.
 
With over a decade of experience in science communication, Carissa also explores how creative expression, through letters, social media, or digital campaigns, can transform awareness into action, and how small, personal stories can influence global change.
 
This conversation is a reminder that youth are not just the leaders of tomorrow, they are shaping the future today.
