...except for the huge piles of salt.
If the salt was not waste, surely people would already be extracting it from the brine and the existing methods would also be "without waste".
- eimrine 4mo agoPersian Gulf has 20% more salt in water because of the humans which are throwing the oversalinated waste back into the sea. Dehidrated salt may be a big deal for some areas because of no waste into input.

- tdb7893 4mo agoThrough the magic of Googling "Persian Gulf salinity" it seems like it's more that it's a shallow Gulf in a dry area so it has significant evaporation. Desalination does effect it but it's only a few percent of the total evaporation (which is still surprisingly big) and doesn't sound like the main driving factor or an imminent ecological concern. https://www.frontiersin.org/journals/marine-science/articles/10.3389/fmars.2020.00573/full https://www.frontiersin.org/journals/marine-science/articles... https://www.sciencedirect.com/science/article/abs/pii/S1463500325000071 https://www.sciencedirect.com/science/article/abs/pii/S14635...
- Jblx2 4mo agoI thought the HN-way was to be more charitable than just directly calling out obvious bullshit.
- MyHonestOpinon 4mo agopardon my ignorance. But, all that salt was there already. right? Is it that we have less water there now ?
- fc417fc802 4mo agoIf salt and water flow in but only water flows out you will be left with salt. Same reason that concentrated brine comes out of a desalination plant, or that the dead sea is what it is.
- card_zero 4mo agoHuh, looks like they process about 1/500 of the water in it every year. So enough to make a dent in the salinity eventually.
- Animats 4mo agoLook at a map. The Persian Gulf is a dead end, and all ocean water flow has to come through the Strait of Hormuz. There's some fresh water coming in from the Tigris and Euphrates rivers, but less each year as that fresh water is captured and used, and as global warming increases evaporation. The San Francisco bay has to be actively managed for similar reasons. It's a large body of water with a narrow outlet, fed by a river system from which much water is captured. If too little water comes in from the Sacramento River, the delta will turn to salt water. Managing that is what the Bay Model, mentioned recently, is for.

- mkl 4mo agoThe brine is waste, and the dehydrated salt is also waste. Maybe dry waste is better, but it's still waste.
