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.
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
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.
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.
