World water supplies will not be enough for our descendants to enjoy the sort of diet the West eats now, experts say.
The World Water Week in Stockholm will be told the growth in demand for meat and dairy products is unsustainable.

Animals need much more water than grain to produce the same amount of food, and ending malnutrition and feeding even more mouths will take still more water.

Scientists say the world will have to change its consumption patterns to have any realistic hope of feeding itself.
