Human societies have not just adapted to the natural world. They have steadily learned how to transform it. Drawing on research from archaeology, ecology, anthropology, and evolutionary theory, Erle Ellis, professor of geography and environmental systems at the University of Maryland Baltimore County, explains how cultural practices have evolved to give humans extraordinary influence over the ecosystems that sustain them.

From early uses of fire to cook food and shape landscapes to modern systems like industrial agriculture, global trade, and rapidly growing cities, societies have developed powerful tools and institutions. These social and cultural advances have allowed humans to reshape the planet on a massive scale while improving their ability to survive and thrive.

Understanding the Anthropocene and Human Impact

Ellis is a leading researcher studying the Anthropocene, the current geological age defined by the large-scale impact of human activity on Earth. He leads the Anthroecology Lab, which examines how human societies interact with ecosystems at every level, from local environments to the entire planet. His work focuses on how these relationships can be guided toward more sustainable outcomes.
