This film investigates the future of the world's water, and paints a disturbing picture of a world running out of the most basic of life's essentials.

This is bloody obscene, the more I learn about big business the more I understand the guillotine.
A the end they say that in some places they use 800 litres a day PER PERSON, WTF! We lived quite well for years on about 7 liters pppd, that maybe be a little extreme for most but 20-30pppd should be heaps.

800L per day per person? An average bathtub - as a google search tells me - is around 150L. I'm not sure I want to watch this video now...

Yet to watch it also... but I imagine such a figure could be easily reached by dividing total usage by population. If you lived near an industrial area or near anything with irrigation it wouldn't be hard to reach such a figure.
Also imagine all the water that is 'used' to make the products we buy at the store...
When I used to live in the suburbs we would always be told how little water we used compared to our neighbours when we got the bill. At the time we were using around 140,000L per year... which is 383L per day, 191L per person.
We use a lot less now but I can really see how such a figure could be reached in some areas.

Water is recyclable, many countries recycle sewerage water etc, including heavy industries.. Industries like metal working and mining make more money per kl of water than most other big users. Flood irrigation farming is the most wasteful use of water - but no one talks about it - it is only heavy industry that gets a bad rap. Steel is also recycled so initial water used if calculated against multiple product life - it is not that much water. There is also desalinate of sea water so there is an unlimited supply if you have the energy.

Valid points all. But if water consumption is such an issue, perhaps local government should stop watering their parks twice a day in the middle of winter...

I'll watch the doco tomorrow at work...fast free wifi and no SWMBO looking over my shoulder telling me not to waste time. While the area I live in gets around 1,300mm average precipitation per year, most people also waste a huge amount of water. While I am apparently a freak for having a shower every day, my 4 minute showers still use less water overall than the average person's 20 to 30 minutes a couple of times a week. Meanwhile, the older generation's favourite method for washing dishes is to just rinse each one under high-flowing continually running water. Washing clothes means putting a few items in the sink, then filling it up with water to soak for x amount of time. Empty the sink, refill, then leave to soak again. Repeat a few times, then turn the tap to the highest flow rate and leave on for ten minutes to continually rinse. Apparently this way saves a lot more time and water than the washing machine (NOT!). I always tell friends who are visiting Aus that people don't look too kindly on wasting water. When they say that they don't, I then explain about things like 4 minute showers, regulated sprinkler times, greywater on the garden etc, and wait for their jaws to drop and wonder what backward place they're going to for a holiday.

I couldn't agree more... there's also the matter of appropriate species selection.
For some reason all the park designers try to build to the European ideal then we struggle to keep it green through our climate.
Perth was particularly bad for this, all the new developments put in these huge irrigated parks... which is nice until you start getting your rates notices.

Peer into a glass of drinking water and you are looking at a drop of human history—the water we consume today has been around in one form or another for thousands of years, continually recycled through the atmosphere and back into our cups.

Read the rest of the article here; www.nationalgeographic.com/freshwater/freshwater-crisis.htmlA lot of people misunderstand just how little of the worlds water is actually usable. I'm very interested in the politics of the MDB and the lake... another very misunderstood system.
The drought a few years back coupled with the high water allocations killed most of the natural filtration system that exists within the Murray river. We had a good rainfall this summer so many of the irrigators are pushing to get some of the bought back water claiming there was an over reduction in licences. Without environmental flooding events much of this filter will never grow back and another drought could kill the system for good.
Any large enough scale SHTF event would kill the MDB & lake Alexandrina as it's such a micro-managed house of cards these days. Failure to manage the barrages would quickly turn the lake saline & we'd loose much of the natural lake resources along with all the irrigators who exist around the lake.
So many of these systems around Australia & the world are used to their limits without sufficient thought given to long term resiliency & effective water efficiency methods.
Far too often the political cry is to just build another desal plant rather than address the way in which we use water.
