That's an amazing thing, but it hides the hugely complicated system that makes it all happen. The largely invisible process can make us blind to our connection to the land. Why do we waste so much food, and what can we do about it? What can we do to make agriculture more sustainable? We tackle these questions with our guests Dr Bethany Turner and Dr Ro MacFarlane from the University of Canberra. Interview by Rod
