Different voices. One collective.

The Turtle Talks

The Turtle Talks is a youth-led environmental podcast founded by 15-year-old Sienna CJ to amplify young voices in discussions about our planet.

On the podcast, Sienna interviews conservationists, environmental advocates, volunteers, educators, and changemakers worldwide. She asks questions relevant to young people, explores their stories, and examines how ideas become action.

The Turtle Talks goes beyond raising awareness by making environmental issues personal, relatable, and actionable.

Change does not always have to begin with large organizations or grand solutions. It often starts with a conversation, a question, volunteering, or one person choosing to act.

Each episode invites listeners to learn, think differently, and discover their own ways to make a difference.
