Hay Festival 2026: A Look at a Big Year for the Oceans

From the Hay Festival 2026, BBC Science & Environment brings listeners a discussion about why the oceans may face a defining moment in 2026. The programme looks at the growing importance of ocean science, including how researchers study sea life, water quality, and changing conditions. Speakers highlight that the ocean is not only a home for marine species; it also supports human needs such as fisheries, jobs, and global trade. They also connect ocean health to the wider system of weather and climate, explaining that warming seas and pollution can disrupt ecosystems and reduce biodiversity. The goal of the event is to make these complex topics easier to understand, while showing that public awareness can support stronger action. By combining science with conversation, the session invites people to ask questions and consider practical steps for protecting the sea.
