On this week's show:

We take time to listen to three writers and activists who help us see our world differently, helping us to imagine other possible futures.

Hannah Donnelly is a Wiradjuri woman from New South Wales. She is the creator of the Sovereign Trax music blog, celebrating Aboriginal and Torres Strait Islander music and culture. Hannah is also the co-editor of the Sovereign Apocalypse. Her writing experiments with speculative fiction and future imaginings of Indigenous responses to climate change.

Claire G. Coleman is a Noongar woman from the south coast of Western Australia.

She writes fiction, essays and poetry. Her debut novel 'Terra Nullius' is published by Hachette Australia, 2017.

Ursula K. Le Guin was a writer of fantasy, science fiction and poetry. She created worlds that were both alien and also entirely relevant to our own.

Earth Matters #1126 was produced by Teishan Ahearne.
