National Geographic: A Vegan Diet Saves 600 Gallons of Water Per Day

Here is what National Geographic has to say about water consumption and food choice:

Diet:

The water it takes to produce the average American diet alone—approximately 1,000 gallons per person per day—is more than the global average water footprint of 900 gallons per person per day for diet, household use, transportation, energy, and the consumption of material goods.
That quarter pounder is worth more than 30 average American showers. One of the easiest ways to slim your water footprint is to eat less meat and dairy. Another way is to choose grass-fed, rather than grain-fed, since it can take a lot of water to grow corn and other feed crops.
A serving of poultry costs about 90 gallons of water to produce. There are also water costs embedded in the transportation of food (gasoline costs water to make). So, consider how far your food has to travel, and buy local to cut your water footprint.
Pork costs water to produce, and traditional pork production—to make your sausage, bacon, and chops—has also been the cause of some water pollution, as pig waste runs into local water sources.
On average, a vegan, a person who doesn't eat meat or dairy, indirectly consumes nearly 600 gallons of water per day less than a person who eats the average American diet.
A cup of coffee takes 55 gallons of water to make, with most of that H2O used to grow the coffee beans.

Does this information from National Geographic shock you?

In the midst of the severe California drought, it's important to keep in mind the factors depleting the groundwater supply. Since the biggest portion of California's water goes to growing livestock feed, we can start to use the water that remains much more wisely by eating crops directly instead of through a "middle animal."
