The answer to providing clean drinkable water to the bulk of humanity is the same as it always has been for about the last 7,000 years.
Problem solved faggots..... Seriously!
Not only has beer been the breakfast of champions for a huge amount of Western history, But has provided safe drinkable hydration generations.
Sure it sounds a bit degenerate by current standards having a beer for breakfast, lunch and dinner. But actually in the past it made sense. Beer has nutritional value, calories, and was free of the bacteria commonly found drinking water.
In fact if I remember my history correctly some British doctors actually figured out that cholera was a waterborne illness when they studied the outbreak maps of London and realized that people that lived around breweries didn't suffer cholera outbreaks like everybody else.
Just walking down the beer section in the supermarket the selection of beers there is mind boggling. Despite what Barcy and some of the other Euros think. Talking just a regular grocery store, by my place, the selection of beers available is ridiculous. I have no idea how they can possibly find a market where there's a demand for such a variety. Economically it just doesn't make any sense to me. The Beer market is so over saturated with the plethora of beers that they should be selling it for dirt cheap.
Current price of beer has to be completely artificial. A little bit of government regulation to make this valuable commodity affordable to all humans, exporting of our beer technology to the nations most in need, a little education and worldwide hydration crisis is resolved.
You can go with HM and Foota plans, force compliance, Make people drink recycled piss.
Or follow my vision, for happier, more relaxing, and more peaceful world.
Don't bother trying to argue the point, you know I'm right.
