But it isn't right now and you'd be talking about several orders of magnitude more than is currently being produced.
Current production appears to be something along the lines of 51.8 billion cubic meters [1] of brine each year being produced. Basically 1.5 brine per 1 desalinated water. If we use the YC page I linked above, " create millions of 1 km2 oases" let's assume roughly 2ft deep (61cm) and just 2 million oases... to fill them once you are talking about 1,200,000,000,000 cubic meters of water so 1,800,000,000,000 cubic meters of brine 34.75x as much brine as is currently being produced just to initially fill them, now factor in evaporation and water lost in algae you remove (to go sequester the carbon) and you're probably talking hundreds of times as much brine as currently produced. That's just for 2 million, what if you need 10 million of the pools? 20 million of them?
That's 1800 cubic kilometers of brine just to fill 2 million of the above pools, Lake Ontario is 1,640 cubic kilometers for some reference.
