The Grass Ceiling was originally conceived as a podcast series to discuss topics in sustainability. At first, the goal was to break down the complexity and communicate the basics. To an extent, we’re still doing that with this project, but there’s always more to learn and more to document along the way.
As that learning continued, we also decided that we wanted to go beyond just environmental considerations – and the name of the podcast was born. We want to cultivate dialogues about sustainability that aren’t centred around the “environment” as we traditionally perceive it – somewhere green, somewhere with trees.
That’s why we’re bright yellow! Proudly different. And sneakily Australian.
Yellow is the colour of Wattles blooming in spring – a signal that the turtles are ready to nest and that soon, the eels will be plentiful. We are the colour of gold, shining through the ages on glorious Incan crowns, Conquistador’s spoils, semiconductors, and spacecraft. We are the colour of sunset, sunrise, and supernova – the cosmos at its most serene and savage. There is so much more to sustainability than just the green. We want to show you glimpses through that kaleidoscope.
We’ll explore the familiar regularly too. It’s impossible not to. But we also want to bring a range of topics to the forefront that don’t usually get as much attention. We hope you’ll join us on this journey, as we take each other on a guided tour of sustainability, that’s sometimes more of a guided detour instead. Getting lost can be fun. Exploring can be fun.
