We can definitely agree there is a lot about our current food systems that isn't sustainable. But what's harder to agree on is what we need to do to fix it for the better, while still ensuring everyone on the planet has enough to eat. Everyone has an opinion about what food we should eat and what food we shouldn't, what food systems are harmful and which are sustainable... but those opinions are often at odds. Why are we so passionate about what we eat and how that food gets to our plates? Host Rachelle Saunders talks with development chef and author Anthony Warner about the complexities of food and his new book "Ending Hunger: The Quest to Feed the World Without Destroying It".
