This week, Grace speaks to Troy Vettese and Drew Pendergrass about their book Half-Earth Socialism. They discuss the problems with proposed solutions to climate breakdown like geoengineering, how neoliberals are coping with the recognition that state planning will be necessary to tackle climate breakdown, and how we can build coalitions to make sure that planning is democratic.Thanks to producer Sarah Hurd for filling in this week and to Left Book Club for making this episode possible.
