The Dawn of Everything by David Graeber and David Wengrow. Showed all of the archaeological evidence for vast time periods where alternate governance models were put into practice, and how the history of progress that we are given is not the whole story. Useful for seeing that we are in a local minim, and can evolve into something better.
Dark Emu by Bruce Pascoe. Goes through the diaries and historical evidence of the early interactions with Australia's Aboriginals. Shows how over time their agricultural practices, towns and living environments were destroyed and replaced with a narrative that they were backwards and not using the land. Good example of how sustainable practices can look like unused natural spaces, and thus dismissed as poor uses of space.
