Including celebrated writers like Bill McKibben and scholars like Gus Speth, as well as young activists, the authors draw on direct experience in grass-roots organization, education, law, and social leadership. They share a belief that private fears about deadly heat waves and disastrous hurricanes can translate into powerful public action.

Combining incisive essays with success stories and web resources, the book helps readers answer the most important question we all face: "What can I do?"
