Half-Earth Socialism

Half-Earth Socialism is a book I co-authored with environmental historian Troy Vettese on how we can get out of our current ecological mess. Published in April 2022 by Verso Books, you can order it from the publisher here. The book has been translated into Italian, Thai, Korean, Spanish, and Swedish; all translations can be ordered from my books 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)!
