The majority of people on Earth will face severe water shortages within a generation or two if pollution and waste continues unabated, scientists warned at a conference in Bonn Friday.
“This handicap will be self-inflicted and is, we believe, entirely avoidable,” read a document entitled The Bonn Declaration issued at the close of the four-day international huddle.
The declaration points out that humanity uses an area the size of South America to grow crops and another the size of Africa to raise livestock.
Two-thirds of major river deltas are sinking due to groundwater extraction, and tens of thousands of large dams are distorting natural river flows on which ecosystems have depended for millennia.
Much damage is being done by river pollution from sewer drainage or agricultural fertiliser and pesticide use.
Whilst I agree we need to stop wasting water, 2/3 of the Earth is covered in the stuff. Building more desalination plants is the answer, using renewable energy to power them.
I seriously doubt the oceans will run out for a few million years.
The largest desalination plant is the sun and it's free. If we can use solar energy to heat water and turn steam turbines we surely can use it to do the same with desalination of salt water. Doubtful that they would do this as it might work too well and then there wouldn't be any money in it.
It is a totally backwards world that we live in..
n addition, the film is super thin — just a single atom thick — so that the water simply “pops through the very very small holes that we make in the graphene and leaves the salt behind,” John Stetson, the chief technologist at Lockheed for this initiative told Business Insider. Lockheed anticipates that their filters will be able to provide clean drinking water “at a fraction of the cost of industry-standard reverse osmosis systems,” their press release says. Water-poor regions of the world will be the first to benefit.

This is a water planet, instead of BS and the war machine, put de-salination plants around the planet. We could be growing food and creating jobs in the driest of places if pipelines were built for water rather than oil.
Yep, I would imagine the price of modern military equipment like fighter jets, a naval warship, a few nuclear bombs/missiles -- could be used for desalinization.
The problem is that helping people is not good for business, and there are some greedy uncaring leaders in place most everywhere around the world.
