We have become incredibly good at producing food. In doing so we have transformed our planet. Yet when we go to the supermarket or eat at a restaurant, the supply chains, labour and environmental impacts that went into our food are all but invisible.

Those impacts are huge. Today, humans and livestock make up 96 per cent of all mammals. Agriculture consumes about 70 per cent of global freshwater, and is responsible for some 80 per cent of deforestation. And yet despite producing more than enough food to feed everyone on earth, every day a minimum of 800 million people go hungry, while a fifth of all food produced for human consumption goes to waste.

Clearly, something has got to give. Thankfully, here to help us out of the mess is Dr. Sonali McDermid, a climate scientist and Chair of the Department of Environmental Studies at NYU. In this episode, she breaks down how climate and ecological crisis threaten our food systems — and how we can feed the world without wrecking the planet.
