In Changing Tides, Alejandro Frid tackles the big questions: who, or what, represents our essential selves, and what stories might allow us to shift the collective psyche of industrial civilization in time to avert the worst of the climate and biodiversity crises? Merging scientific perspectives with Indigenous knowledge might just help us change the story we tell ourselves about who we are and where we could go. As humanity marches on, causing mass extinctions and destabilizing the climate, the future of Earth will very much reflect the stories that Homo sapiens decide to jettison or accept today into our collective identity. At this pivotal moment in history, the most important story we can be telling ourselves is that humans are not inherently destructive.
