Listening to the Ocean: The Path to Ocean Conservation | Rafaela Prado Cardoso | TEDxPraça Gil Eanes
In this talk, Rafaela Prado Cardoso explores the ocean from a perspective we rarely consider: through sound. She reveals how, beneath the surface, life depends less on sight and far more on hearing — and how understanding this can transform the way we relate to the sea.Drawing from her work at SOMAR, a marine conservation and bioacoustics organization in Portugal, Rafaela presents a world where dolphins use unique whistles as names, whales sing songs that span oceans, and even tiny shrimp produce noise for survival. She also addresses the growing issue of underwater noise pollution and its impact on marine life, urging us to think about how human activity is drowning out vital natural communication.Blending science, storytelling, and emotion, this talk is both a call to awareness and an invitation to connection. Because we protect what we understand — and when we learn to truly listen, we begin to care in deeper ways. Rafaela Prado Cardoso is a Brazilian oceanographer and co-founder of SOMAR - Marine Conservation and Bioacoustics Association, a nonprofit based in the Algarve, Portugal, that uses sound as a powerful tool for ocean literacy and conservation. She currently leads projects that merge science, art, and education to bring people closer to the ocean in inclusive, sensory, and emotionally engaging ways. Through immersive experiences — from underwater soundscapes to interactive exhibitions — Rafaela invites audiences of all ages and backgrounds to listen more deeply to the sea. Her work highlights how sound can reveal the hidden life of the ocean and foster a more conscious, connected relationship with the planet.

- 19:19Manifestation: Will the universe really hear your prayer? | Tâm Bùi | TEDxFTU HanoiAppearing at the event with a topic both familiar and captivating, Tâm Bùi left an unforgettable impression at this year’s TEDx FTU Hanoi in auditorium D201. Through his talk, “Manifestation - Will the Universe Really Hear Our Prayer?”, the speaker sought to share the practicality of the Law of Attraction and how to apply it correctly. From the perspective of a photographer, writer, and traveler who has practiced the Law of Attraction for over a decade, Tâm Bùi delivered a compelling message: cultivating mindfulness is how we gain control over our actions, words, and thoughts. Concerned about the skepticism surrounding the Law of Attraction and its misapplication, he shared three thought-provoking lessons: 1. Don't manifest what beyond our reach! 2. Practise mindfulness everyday so manifesting can happen faster! 3. Whether breakpoint can happen or not, whether the universe hear your prayer or not, lies within you. Through this unique topic, Tâm Bùi conveyed an empowering message to the audience: No one but you decides whether a breaking point will occur, and whether the universe will truly hear your prayer. "We don't fear movement because youth only comes once. It's never too early or too late. If you want to, start today." This is one of the profound quotes from Tâm Bùi, a photographer, travel blogger, and author of the travelog "Bụi đường tuổi trẻ" His journeys and invaluable experiences in India, Tibet, China, and more have been memorable, offering him a myriad of emotions and a fresh perspective on life and youth. Unlike other storytellers who use words, he narrates through images. A prime example is his iconic photobook, 'Rooster, Hen & Dreamers,' which beautifully captures the everyday lives and unique perspectives of “special” families.
