Earth in Human Hands: The Rise of Terra Sapiens and Hope for Our Planet

NASA astrobiologist and renowned scientist Dr. David Grinspoon brings listeners an optimistic message about humanity's future in the face of climate change.

For the first time in Earth's history, one species -- humans -- is knowingly altering our planet's evolution, exerting increasing influence, and attempting stewardship. How we handle this juncture may very well determine the fate not just of our species, but of life, and the planet. Without minimizing the challenges of the next century, Grinspoon shows how the 10,000-year view is both essential and hopeful. Having spent his career studying the ways in which planets undergo catastrophic changes, he suggests that the present moment is not only one of peril, but also great potential. We need a new vision of the future, one in which we have embraced our role as planet-shapers, and learned to use our technological skills to enhance the survival prospects not just of humanity but of all life on Earth.
