Michael Olson hosts Michael Grunwald, Author of "We Are Eating The Earth"

Some say the big problem is not fossil foods, it’s the food we eat!  If what they say is true, we simply must ask:

 Are we really eating up the earth?

Topics include why author Grunwald would say, “We are eating the earth;” how the production of food causes so much of the greenhouse gases emitted into the atmosphere; whether agriculture can be made to reduce its pollution.
