For the first time ever, love letters consciously written by elders of one geologic epoch to the young of another. Our children's and grandchildren's generation will face a different world, one affected by climate instability, mass uncertainty, and breathtaking extinction. In fact, the next generation will face the reality that human activity is changing the planet from one geological epoch to another. From this vantage point--two generations across two geological epochs facing a fundamentally changing planet--Larry Rasmussen writes to his grandchildren. As a grandfather invested in a green earth and climate justice as well as a scholar of faith-based earth ethics, Rasmussen bridges this gap between generations to write to the future about climate change, global citizenship, democracy, and legacy. In topics ranging from "A Viable Way of Life" and "Democracy" to "Where We've Come From" and "Who We Are Now, " Rasmussen explores the large questions of justice, meaning, and faith, encouraging us to speak to and look to the future generation and their future world.
