Guarding Eden tells the personal stories of twelve ordinary people who were so concerned about climate change that they altered their lives to do something about it. Some did quiet backroom work in research, drafted submissions or wrote to politicians; others decided to go public, really public - one was part of the team occupying a 160-metre power-plant chimney, one went on a hunger strike publicised around the world, another started the Lock the Gate Alliance. They come from all walks of life: there’s a nurse, a musician, an insurance broker, a teacher, a lawyer, a vet.

Surprisingly touching, Guarding Eden makes an issue as complex and controversial as climate change feel human and deeply real.
