To me it is yes – but so what.
What are the actual numbers?
About 500,000 cubic km of water falls as rain each year. About 80% of it over ocean – so let’s forget about that, which leaves about 100,000km3 falling over land.
How much water does a person really need.
To meet your personal needs for drinking and washing and to irrigate about 300m2 of land to provide relaible organic food requires about 3m3 per day – or 1,000 m3 per person per year. Current rainfall over land is about 15,000 m3 per person per year. Abundance!
We do not have a problem of lack of water. We have issues about allocation, storage and distribution of water.
We have many old technologies which are very wasteful of water, but because it is cheap no one really cares.
We are not short of water.
We are short of ways of thinking that incentivise us to use the abundance of water that does exist wisely.
We don’t need large scale desalination.
We just need to get away from money.
