Episode 234 Autumn Blum Stream2Sea

In this episode of The BiG Scuba Podcast, Gemma and Ian catch up with a former guest, Autum Blum. She is the founder of Stream2Sea and a passionate diver, cosmetic chemist and ocean advocate. Autumn shares the story behind Stream2Sea and the moment a dive in Palau made her question what we were putting into our oceans through sunscreens, shampoos and personal care products. We chat about **reef-safe claims, aquatic toxicity, marine-friendly ingredients, sustainable packaging and why reading the ingredients on your sunscreen really matters**. Autumn also talks about her passion for diving, shark diving, technical diving, the Women Divers Hall of Fame and her hopes to experience UK cold-water diving. A fascinating conversation about **diving, science and protecting the water we love.** Whether you are already a diver, a keen snorkeler or simply curious about exploring beneath the surface, this episode is packed with inspiration and a reminder of why we love the ocean and the amazing community that surrounds it.
