Listening to "Animal, Vegetable, Miracle" in the car

I have a lot of time in the car, with the school commute, so I'm listening to Barbara Kingsolver's "Animal, Vegetable, Miracle". It's interesting to hear her talk about the drought in the South; it's a tough time here. We are saving the cold water that runs out of the shower before it warms up, and using it to water the bushes in the front of the house. It's astonishing to see how much water we are wasting.
