Did the Book Change the Industry?

My guest this week is Eric Schlosser, the investigative journalist and author whose work has fundamentally changed how we think about what we eat. Fast Food Nation was a landmark book that exposed the abuse of animals and the exploitation of workers at the heart of America's food industry. 

Now, 25 years after it was first published, Schlosser says he is astonished that not only has the industry failed to improve, in many ways it has gotten worse. And yet, despite this, he still believes change is possible.
