Ok lately I've been researching this topic and after watching Blue Gold World Water Wars (
http://www.bluegold-worldwaterwars.com) I watched this documentary called Flow....
http://www.flowthefilm.com/I was shocked.....here is a rundown of what I saw.
* Nestle has been extracting millions of gallons of water from rural US towns without paying for it, they rent a building and pump the water out freely, ruins the ecosystem and limits everyone's water. When you try to stop them they just appeal in court and resume pumping. The irony is that the same water they extract is being sold back to the community for 10 times the price as bottled water.
* they showed in Africa Suez forces ppl living in poverty to buy cards which they swipe to get water from public taps
* Then they went to India and showed how coca cola was pumping water from the ganges river, polluting everyone drinking water and then giving "fertilizer" to the ppl which was actually toxic waste containing cadmium etc and was killing crops and animals.
* They showed that the world bank is about making money and the best way to do that is invest in megaprojects that countries cannot afford themselves, so what do they like.....Dams. They finance those and lock the countries into long term debt thus controlling the water supply. Once these dams are built they displace millions of people, ruin the ecological system and on top of that everything in the dam dies and it starts releasing methane about 10 times that of a coal plant.
* The majority of bottled water brands in the US such as Perrier, Arrowhead, Calistoga, Deer Park, Ice Mountain, Ozarka, Poland Spring, Zephyrhills etc. are all owned by Nestle, no one ever questions where that water comes from, it is not regulated and many times they don't even pay to extract the water
* they showed in india where a group of farmers created their own aquifers by directing rain water into the ground and they created wells....the authorities sent them letters stating that what they were doing was illegal.
