Water will be a huge issue right here in the U.S. The whole of the west has very little water and the aquifer in the middle of the country is being sucked dry by too many straws in the ground. CA is sinking from mining ground water and the accompaning subsidence means there's no room for water to seep and replace whats been drawn out. T Boone Pickens owns more private water rights than anyone in the U.S. wonder what he'll charge for water. My favorite movie on this issue is "Chinatown"

I am most concerned, people starving and dying of thirst hurts me deeply! But, one of my dearest friends comes from South Africa (lives in Vietnam now), so I feel even more sensitive! (Ofcourse she feels my pain for trump.) The government is mostly to blame for the disaster which may make it difficult to get outside help! I don't understand how a government cannot/want, care for the people? This is a modern age, not the dark ages! I feel helpless...

People just do not want to look ahead. Watch this space, within 10 years much of the water infrastructure in capital cities in Australia will need replacing. Far greater populations now depending on them, pipes needing replacement in highly populated areas is a much bigger job than laying them before there is any construction. Doable, but at great cost and inconvenience. There is no wisdom in any of this. Great concentrations of populations may be great for cutting some costs in infrastructure but it creates other problems and inefficiencies.

Be concerned....

The solution is to get the population down to 3B and keep it there. Right now it's 7.5B +.

I live in Arizona and Tucson is a disaster waiting to happen. There are no rivers running into that city. Everything in groundwater in the middle of a large desert. They tried bringing in water from the Colorado, a couple of hundred miles, but it was so toxic that it ate all the plumbing in the houses where it went. They are building like there is no tomorrow and one day soon, there won't be.

We should all be concerned. As an hydraulic engineer in the water resource area, we knew that rainfall patterns were changing 30 years ago. The extremes were changing. We have cycles of wet and dry. On the dry end, the droughts were getting longer. If your source for drinking water is surface water runoff, then it is at greater risk. (a simple version). And in a lot of places, the groundwater aquifer is being mined. Water table is going down as out take exceeds the recharge. Back when I was young, we went fishing in some ponds that connected, and had a spring at upper end. Irrigation came in, and in a few years, the spring quit running.

Yes , the world should be concerned. We've covered this subject in a couple other posts. Various critical issues are happening all over - much right here in the US.
We're treating our water like it is an infinite source - which it most definitely is not.

If you can, read "Mirage" by Cynthia Barnett - a real eye opener !
