Response to Postel Discussion

I enjoyed hearing all of the opinions on Postel's water article. However, it seemed in class that everyone pretty much agreed with Postel, and nobody challenged what she wrote. Our class as a whole agreed that we needed to be more water conservative. Also, I think most of our class was as surprised as I was that water was even an issue. In this video: http://www.youtube.com/watch?v=wWiabqZ1isE Dr. Peter Evans  speaks about the importance of renewable energy. About halfway through the video, Dan Walter, General manager of Food and Beverage Energy Solutions at GE speaks about the importance of water conservation, more specifically. I am more interested to hear Mr. Walter's advice and opinions on the subject, which he did not elaborate on due to it being such a short video. I am astonished at how much water it takes to make food and beverage, and would love to know more details on that subject.
