Dominic and Cymene chat about community wind power, bioplastics, sucropolitics, and the inevitability of edible children's toys. Then (11:10) Cymene sits down to talk with economist-turned-philosopher John Broome, Emeritus Professor at Oxford and author of Climate Matters: Ethics in a Warming World (Norton, 2012) to talk about morality, ethics and climate change. John explains why he thinks moral messaging around climate change has been ineffective thus far and how we can appeal to self-interest to stimulate climate action. We talk about the intergenerational externalities of high carbon lifestyles, how large scale actions like a carbon tax could change the identity of future generations, and the need to reform mainstream economic theories of efficiency, value, goodness, and nature. John argues that our duty to future generations is not a duty of justice but of making the world a better place. Does economics have a place for ethics? Listen on and find out!
