How the fridge changed food | Nicola Twilley

Scientists estimate that 80 percent of life on Earth is still unknown to humanity. But as global temperatures rise, habitats shrink and food and water sources dry up, we're losing these species faster than we can discover them. AI naturalist Sara Beery reveals how the knowledge to study (and save) the natural world may already exist, buried in millions of images, recordings and observations. We just need to learn how to read them before it's too late. Hosted on Acast. See acast.com/privacy for more information.

Impact investor Tom Chi challenges a dangerous assumption: that economic growth and ecological health are opposing forces. He reveals how advances in AI and robotics are enabling a radical shift towards innovation as a force for restoration. Imagine mines that extract less, farms that regenerate soil and fleets of robots that can plant 100,000 mangroves in a single day. What if the same technologies that power our economy could actively repair the planet at the same time? Hosted on Acast. See acast.com/privacy for more information.

In a world that prizes certainty, hot takes and instant answers, what happens when we celebrate the power of ... not knowing?
