Supply chain issues, labour shortages and climate change are posing unprecedented challenges to the world’s food supply and with the population expected to climb to 10 billion by 2050, we'll need to produce more food – not less. This problem has sparked a major wave of innovation in food production– in vertical farming and in cellular agriculture, which creates animal protein without the animals. On this week’s episode of The New Reality, Krista Hessey explores the future of our food supply and takes us inside two facilities that look nothing like the farm you know. Plus – from a supply chain crunch, to a housing crisis, to a shortage of life-saving donor organs: 3D printing is providing solutions to all these challenges and more. It has evolved from novelty to a sky's-the-limit technology. Marianne Dimain looks inside the rapidly evolving world of 3D printing, and meets some of the key players pushing the frontiers of modern manufacturing, construction, and medicine.
