Hi, I'm Drew. Welcome to my artisanally-crafted, fair trade, GMO-free website! I am an assistant professor of environmental studies at Oberlin, where (1) I lead a lab that uses satellite data to track pollution back to its source, and (2) I think about connections between technical knowledge, social movements, and democracy. Also, I am reluctant to resort to black magic. Navigate as follows:

Complexity in the air

This story covers the history of the popular reception of complexity and chaos, and how, in the process of translation from natural science to popular culture, ideas like complex systems and the butterfly effect have been used to buttress both deeply reactionary political projects and left-wing ones. This essay asks: Does complexity have any inherent politics? If it does, what are the implications for markets, planning, and collective environmental action?

Nichtstun fürs Klima! Brecht’s Daoism, Useless Trees and the Action of Non-Action (video)

12 February 2026 | Watch here

My co-author Troy Vettese and I talk about the surprising resonances between the playwrite Bertolt Brecht and Laozi: both figures praise forms of non-action and uselessness. In conversation with Heinrich Detering and Alexander Karschnia, comment on the implications for climate action.

Additional interviews and media are available on my interviews page.

Play Half-Earth Socialism: A Planetary Crisis Planning Game!

The Half-Earth Socialism planning game allows anyone to try their hand as a global planner of a post-capitalist science fiction society. The player aims to overcome the environmental crisis, global poverty and inequality, and pursue other goals, all while keeping global parliament happy (else the player will find themselves out of a job, or worse). Consider it a sandbox where you can play with a wide range of technologies and policies spanning different fields and ideologies. The game simulates the impact of your decisions by calculating emissions and using a real climate model (HECTOR) to work out the climate effects, while also simulating impacts to the food system and biodiversity, among other natural systems.

The video game is based on my book, Half-Earth Socialism, and was made by a team including Francis Tseng, Son La Pham, Troy Vettese, and myself. For more, you can visit the book homepage or play the game for free in your browser (mobile/desktop both supported)!
