In "Earth: A Tenant's Manual," distinguished geologist Frank H. T. Rhodes, President Emeritus of Cornell University, provides a sweeping, accessible, and informed guide to the home we all share, showing us how we might best preserve the Earth's livability for ourselves and future generations.

The book, published in June by Cornell University Press, is a comprehensive look at the structure of the planet, an analysis of how it is being depleted, and a road map for sustainability.

In this "Chat in the Stacks," Dr. Rhodes discusses how new resources, new priorities and policies, and most of all, new knowledge, can lead us to a sustainable future.
