Our grandchildren in the late 21st century will be forced to eat vevetables as the global population soars to more than 10 billion...?

It simply takes too much water to grow a steak. In a new report, leading water scientists say the human population would have to switch to an almost entirely vegetarian diet by 2050 to avoid catastrophic global food and water shortages.

"There will not be enough water available 芒聙娄 to produce food for the expected 9 billion population in 2050 if we follow current trends," Malin Falkenmark and colleagues at the Stockholm International Water Institute stated in the report. By their estimation, there should be just enough water to go around if humans derive just 5 percent of their calories from animal-based foods by midcentury, instead of the 20 percent of calories that they currently get from meat, eggs and dairy.

It's a simple numbers game: Cattle, for example, consume a shocking 17 times more grain calories than they produce as meat calories. All that lost grain (which humans could have eaten) requires water. "Producing food requires more water than any other human activity 芒聙聰 and meat production is very water-intensive," Josh Weinberg, the institute's communications officer, told Life's Little Mysteries.

They'll be forced to eat less meat, experts say. But not by government intervention or their own inner moral compasses. For most people, the choice between a juicy, medium-rare sirloin steak and a humble plateful of soybeans won't turn on which one is sucking wells dry in Texas. It will hinge on the contents of their wallets.
