The article seems more about all the water trapped in the Earth mantle. It mentiones it about a dozen times ;-)

There was an intersting comment related to that on reddit AskScience today: http://www.reddit.com/r/askscience/comments/204xxh/is_it_jus...

Another example of HN preserving a useless headline.

Learning some 2% of water is fresh and the need to conserve water or it will run out by 2050 was a lie. There will always be fresh water and oil. The price will not soar when supply is limited, there usually happens to be a new discovery. Eg. The US is a huge unexploited oil field

The word you're looking for is wrong, unless you're claiming that there was a conspiracy to keep this knowledge a secret.

I don't like being the tinfoil hat in a discussion, but given that what most tinfoil hats have been thinking wrt NSA, etc have been proven true thanks to Snowden, maybe there is a conspiracy to keep clean fresh water a secret to start a civil war on water rights in the US.

And if not, it'd probably make for a good movie.

As a person who thinks the opposite, this comes as a shock to me. Care to explain?

It won't ever be economical to extract water from 600km below the surface. Also, oil won't last forever.

Well, the stone age didn't end for lack of stones.

It's economical to desalinize seawater (once memorably [to me] described as "the most worthless substance in the world") now. We don't do it because using already-fresh water is even cheaper, but desalinization isn't exactly expensive.

I haven't read the full article. But somehow it surprises me that the diamond was found in Brazil and not a single author is at least from a Brazilian university.
