The Green Ages

In *The Green Ages*, historian Annette Kehnel delves into medieval sustainability practices, highlighting communities that implemented sustainable systems such as barter trade, sustainable fishing, common lands, and crowdfunding for infrastructure.

The book draws parallels between these historical practices and modern sustainability needs, demonstrating that premodern societies had innovative and effective methods for living sustainably.

Kehnel's work challenges the conventional view of the Middle Ages and offers practical lessons from the past to address contemporary environmental issues.
