Speaking Topics
Storytelling as an Indigenous practice is alive and immersive, as much about the moment and the listener as about the teller. For decades Clayton has toured extensively as a public speaker, engaging audiences at venues around the world and inspiring listeners to take action for climate justice and decolonization.

Clayton can speak on a variety of topics concerning Indigenous Rights, the environment, and crucial issues about land and the extraction industry.
