The changes we humans have made in recent decades have altered our world beyond anything it has experienced in its 4.5 billion-year history. Gaia Vince decided to travel the world to explore what all these changes really mean for the people living on the frontline of the planet we've made. She found ordinary people solving severe crises in ingenious, effective ways. Gaia looks at how humanity's changes are reshaping the living planet and identifies some of the ways we need to engineer Earth for our future, and how we might survive the coming centuries.
