Our future diet will be shaped by diverse forces. It will be shaped by novel technologies and the logic of globalisation, by geopolitical tensions and the evolution of cultural preferences, by shocks to the status quo - pandemics and economic strife, the escalation of the climate and ecological crises - and by how we choose to respond. It will also be shaped by our emotions. It will be shaped by the meat paradox. Rob Percival, an expert in the politics of meat, searches for the evolutionary origins of the meat paradox, asking when our relationship with meat first became emotionally and ethically complicated. Every society must eat, and meat provides an important source of nutrients. But every society is moved by its empathy. We must all find a way of balancing competing and contradictory imperatives.
