How Our Food Choices Shape the Future of Humanity | Dr Peter Johnston

In this World Food Day presentation, Dr Peter Johnston, accredited practising dietitian, lifestyle medicine practitioner and Fellow of the Australasian Society of Lifestyle Medicine, explores the profound connections between our food choices, human health, ecological sustainability and the future of humanity. Drawing on decades of experience studying nutrition, food systems and the environment, Peter examines how our current food systems contribute to some of the world's most pressing challenges — from chronic disease, biodiversity loss and deforestation to climate change, food insecurity, resource depletion and ecological overshoot. He also explores why transitioning towards more plant-based food systems could offer multiple benefits for people and planet, and what individuals, communities, governments and institutions can do to support that transition.
