Meat-Eaters Soak Up the World's Water

From the Guardian:

Governments may have to persuade people to eat less meat because of increasing demands on water supplies, according to agricultural scientists investigating how the world can best feed itself.
...
"Western diets, which depend largely on meat, are already putting great pressures on the environment. Meat-eaters consume the equivalent of about 5,000 liters[1,100 gallons] of water a day compared to the 1,000-2,000 liters used by people on vegetarian diets in developing countries. All that water has to come from somewhere."

The consensus emerging among scientists is that it will be almost impossible to feed future generations the typical diet eaten in western Europe and North America without destroying the environment.

So treat your mother right--don't have a cow.
