In a previous post I asked about the feasibility of connecting the ocean to a dried sea bed with hand tools and it was pointed out how environmentally disastrous this would be.
So the bronze age geo-engineers got their wish and flooded a desert with salt water. Now they have a huge salt lake with minimals outflow and significant inflow from the ocean and a few rivers that fed some preexisting salt lakes in the basin.
The sand and desert rock had quite a bit of phosphorus in them, which coupled with the lack of outflow has made the waters perfect for algal blooms. The blooms are so great and frequent that there are very few fish at all, and the ones that are present are dangerous for human consumption. There are such great concentrations of algae year round that the sea has a sickly green color.
So how can humans who have been pushed from their oasis homes adapt to life alongside a massive salt water lake that has practically no fish? What resources could they glean from such a vile place?
Note: They have access to fresh water from the inflowing rivers but they can’t settle far from the coast due to hostile neighbors.
