In our latest episode of the Healthy Seas Podcast, we explored an innovative approach to education that’s not just about learning—it’s about living and interacting with the world around us. Our guest, Dr. Aristea Kyriakou, founder of the European Outdoor Education Hub, shares fascinating insights on how outdoor education can transform not only how students learn but also how they connect with their environment.

Outdoor education is more than just taking lessons outside. It’s a comprehensive methodology and philosophy that places students in natural settings, engaging them directly with their environment. Unlike traditional classroom-based instruction, which often relies on theoretical learning, outdoor education emphasizes experiential learning. This approach allows students to interact with their surroundings, engage multiple senses, and gain practical understanding through hands-on activities.

Aristea’s work with Healthy Seas in our Operation Ghost Farms exemplifies this methodology. By combining cleanups of abandoned fish farms with educational activities for kids, the program not only addresses immediate environmental issues but also fosters a deep, personal connection between students and their natural surroundings.

Listen to the full episode to learn how outdoor education can revolutionize learning and inspire future environmental stewards.
