I was watching RT (Russia Today) UK earlier and they interviewed a guy from Wikileaks commenting on a few of their latest leaks.
It mentioned that Nestle had some study done that states the earth will run out of water by 2050.
“Nestle starts by pointing out that a calorie of meat requires 10 times as much water to produce as a calorie of food crops".
From what the guy from Wikileaks said, Nestle did have this report done for humanitarian reasons but mainly because they have over 80 or so brands of bottled water. Nestle had only circulating the report internally and did not publish it which of course i guess what qualifies it as leak.
