Will the world have to become vegetarian by 2050?
Here's the article:
Food shortages could force world into vegetarianism, warn scientists | Global development | The Guardian
I think it's kind of an example of "the sky is falling" mentality. Basically it says that the world is facing a water shortage, and "scientists" are recommending that people move to a veg diet (because of all the grain it takes to feed livestock that could go to feed starving people). It's clear that there's an agenda behind this story.
