One of the most fascinating and thought-provoking books of our time is Half-Earth Socialism: A Plan to Save the Future from Extinction, Climate Change and Pandemics (Verso) by Troy Vettese and Drew Pendergrass. The book asks the question: how could we actually have a future for Earth that is both green and socialist? The authors dive into the history of attempts to plan the economy, unearthing useful insights from neglected thinkers like Otto Neurath (developer of the very cool Isotype system). They combine utopian fiction and serious scientific analysis to offer a vision of what humans might be capable of if we put our know-how to work. It's very rare these days to have serious scientific thinkers trying to imagine the path to radical futures, so Pendergrass and Vettese have given us a wonderful gift that all leftists should debate and discuss. The book has an eclectic mix of influences, as the authors write:Half-Earth Socialism draws on ecology, energy studies, epidemiology, biogeography, Chilean cybernetics, history, eighteenth-century philosophy, Soviet mathematics, the socialist calculation debate, Hayekian epistemology, cutting-edge climate modelling, feminist sci-fi, and the forgotten tradition of utopian socialism.Vettese and Pendergrass have even designed a free computer game to go along with their book, in which YOU can attempt to plan the entire global economy, reducing emissions and the destruction of life while keeping the population happy. It's like SimCity but with the whole world, and instead of your task being to build a city it's to maintain a viable eco-socialist global government. GOOD LUCK!
