Study: World Population Increase Could Force Us to be

according to a new study.  From this story in the (UK) Guardian:
Leading water scientists have issued one of the sternest
warnings yet about global food supplies, saying that the world's
population may have to switch almost completely to a vegetarian
diet over the next 40 years to avoid catastrophic shortages.
Humans derive about 20% of their protein from animal-based
products now, but this may need to drop to just 5% to feed the
extra 2 billion people expected to be alive by 2050, according

"There will not be enough water available on current croplands
to produce food for the expected 9 billion population in 2050 if

western nations," the report by Malik Falkenmark and colleagues
