And there's a water shortage?
No! There's a water delivery problem.

Desalination to make sea water useable is an energy intensive process.....You want to learn something about it? Look at Israel who do this on a massive scale.. it is not cheap or simple... The water problem is a FRESH water problem and there are no simple or easy fixes as it is part of climate change. The largest repository of fresh water in the world are the Great Lakes and there is not enough (if any) surplus available to solve the problems in California even if distribution could be overcome.. Lake water levels are not sufficient to provide this water to non-current users. Diversion could cripple navigable waters in the St. Lawrence Seaway... and I do not see anyone damning up that edifice to allow for diversion to California.

Its not that simple... Lets examine Israel, in 1948 there were 600,000 Jews there.. Now there are seven million, most of whom were expelled from surrounding Arab countries following 1948 plus natural growth and some immigration from other nations... You think perhaps that they should have not taken in refugees? The very purpose of the state of Israel is to have ONE safe place on this earth for them to live.. they are going to turn people away? Not going to happen.. no they had to get much smarter.. and they have met the challenge... Same sort of explosive growth in California and Florida - areas with LIMITED sources of fresh water... The whole world has had explosive population growth in these last seventy years.. look at China and that was with an oppressive limit on the number of Children they could have in place for most of that time period... India being the other massive area of explosive population growth.. Fresh water is a finite resource.. and this is from a guy who just came back in to the dock from sailing in Lake Ontario - average depth 300 ft... Its not just where we live - its how we live - we are changing the climate and it is getting hotter and this is affecting fresh water resources...that are dwindling.. so we MUST waste less, reserve more for agriculture and stop watering stupid lawns - we need to be smarter, much smarter... the evaporation from swimming pools alone is ridiculous.. We have to get MUCH more efficient - low flow toilets, irrigation systems for agriculture.. Israel pioneered these technologies out of necessity ... to survive they had to do this and they had to get smart about desalination plants too...

@pdqsailor1 you said "it isn't that simple" then proceeded to give emotional justification. Smh
Fresh water is NOT finite...evaporation/condensation and rain guarantee that. But within localities, the availability of the necessary resource may not keep up with demand. The water that goes down the drain isn't lost...it gets treated and returned to the supply. The planet has plenty of water.
Ppl need to reconcile the idea of home location with water availability.
This notion is difficult for me to process, being in the midwest, where we literally have so much water and humidity in the air, you can feel it. I run a condensor every day during the summer, to remove water from the air. Lol

@easterniowegin collection/concentration, distribution/transportation, purification - population concentrations... none of these issues is an easy one to solve.. and water is a finite resource relative to a growing world population.. No one made any more water but we are making more consumers of it.. so yes shortages are very VERY real...

Those oceans, however, aren't a drinking reservoir. The bulk of the world's fresh oxygen comes from the oceans, fossil fuels come from the ocean. And as excess debris in the ocean slowly degrades over many years it uses oxygen to do so, resulting in less 02 in the ocean. Low levels of oxygen in the ocean lead to the death of ocean animals such as penguins, dolphins, whales and sharks. Excess nitrogen and phosphorus in seawater also cause oxygen depletion. This is the effect of literal islands of plastic refuse found thousands of miles from civilization.
So you can see perhaps why maybe we should leave the oceans alone. They and space are maybe the only things we haven't damaged badly enough that recovery is only possible after we're gone.

And water quality problem. Ocean water has 996 times more salt than what we can stand to drink (0.128 g/ gallon ) vs 127.573 g /gallon. That's like 0.28 pounds of salt and minerals in a gallon of water. Fortunately there's a couple guys at Stanford that have figured out an electronic method of removing salt and other stuff from water without the need of filters. It's slow and therefore takes a bit of surface area, but it is low power and with a bit of crowd funding could transform the world. https://news.stanford.edu/2020/06/01/desalination-solution/

@Tastyfrzz Does anyone have a clue as to how many golf courses there are in America - they are all located adjacent to natural fresh water supplies so they can waste these resources to water the grass... Golf courses in America are the DEFINITION of wasteful mismanagement of scarce water resources.. most golf courses should be closed because of the damage they do to the environment and how wasteful they are in terms of misuse of VAST quantities of water resources..

There is also a human population density problem. Nevada has over three million people but it only has enough water to support 30,000 (population in 1864). LA has four million people stuffed into 502 square miles. That's 1/220 the area of Nevada. So Nevada has over 100 times too many people and LA has over 22000 times too many. Good luck fixing that problem.
Yes…even ridiculous is that Cali has wildfires and it’s literally next to the ocean 🙁
@pdqsailor1 RO is expensive man 😆

@Vivaci yes both in capital and operating expenditures but scaled up it is pretty effective..
DeWayfarer · 61-69, M
Climate is changing. The upflow air currents at the coastlines dries out the air. So little rain.
Some though are working on desalination plants instead of relying on mountain water sheds.

🤔..........Go ahead and drink as much ocean water as your body can handle........Let us know what happens.......
BetweenKittensandRiots · 36-40, MVIP
mostly salt water and desalination is energy intensive....

No.
There is a problem getting drinkable/potable water.

A lot of it would have to be desalinated.
