I think it's good that these conversations are happening - that people appear to be questioning their dietary choices in terms of personal health, the environment, ethics, economics, safety, sustainability, etc.
I do question the accuracy of the information being presented as fact. One item that immediately caught my attention in 'Visualizing a Nation of Meat Eaters' was the factoid that producing 1/4 beef uses 52.8 gallons of water. The source for the information is a report produced by an anti-vegan/anti-vegetarian writer who is clearly a livestock industry shill, Judith Capper (http://www.bovidiva.com
In the following article, John Robbins makes the case for the frequently cited figure of 2,500 gallons of water per pound of beef (625 gallons per 1/4 lb. of beef): http://www.earthsave.org/environment/water.htm
I'm concerned that this NPR series may be a back-handed attempt to re-write the dialogue about meat consumption with phony facts from industry-biased sources.
Lastly, there is a website called, meatweek.com that promotes the consumption of meat. Was the naming of this NPR discussion designed to send a not-to-subtle message?
