“nature doesn’t work this way. Nature de-centralizes and is self-sustaining.”. Good point, however, man needs to work within the constraints of the current technology which means we can necessarily mimic natures processes. Nature has had billions of years to produce its self-sustaining systems.

Jose Alminana’s statement that humans rely on only 1% of the earth’s water for all their needs leads to wrong conclusions. He is refering to naturally occurring fresh water which just happens to be the cheapest source. The oceans have far more than enough water for human needs; all that the ocean water needs is desalinization which other cultures in dry areas of the world have been doing for many years. It’s just more expensive. Ocean going ships, including small yachts all have desalinization units on board to keep an endless supply. So the process can be done at practically any scale.
Also, the earth is a closed system when it comes to water (and almost everything else). None of it “escapes” the planet so the idea that we should “recapture” it is silly in that it never leaves.
The over riding factor is that conserving fresh water and finding clever ways to re-use it is still cheaper than desalinization, or we wouldn’t do it. Isn’t that so?
