The food production experts talk to science presenter Kate Humble. Could cultivated meat from stem-cells grown in a bioreactor beat climate change? Provide real meat but without the slaughter? Cultivated Meat to Secure Our Future: Hope for Animals, Food Security, and the Environment, co-edited by Philip Lymbery, argues that it could be a game-changer in reducing animal suffering and helping solve the growing crisis of climate change, biodiversity loss, and the rise of ill-health. Ed Winters demonstrates How to Argue With a Meat Eater (and Win Every Time), explaining the principles of veganism as a way to create a more ethical, kind and sustainable world, and breaking down every argument used against it.
