what are these?

[apoyusiken]

what are these stuff? now i presume they are to produce salt but the thing is i see them always on maps but i have never seen one in real life. do we really consume so much salt?

[RollyShed]

Are they near the sea?

If so, yes, salt ponds and yes I have often driven past some in this country and yes, we use that much salt world wide.

I think something around 10g per day per person on global average. So the US is like a million tons of salt alone.

 

Those could be for salt production, but also just water storage for irrigation. 

It wouldn't make sense to have these for salt production in the middle of nowhere without access to seawater or other saltwater, usually salt is much easier mined or pumped as brine from salterns.

Not entirely sure, but they almost look like Lithium drying ponds (or something similar to that).

 

As a whole though, we do use a whole lot of salt and drying ponds tend to be the cheaper methods in some areas.

 

For the amount of salt we use, well we use salt in a lot of things including cooking but a whole lot for road salt as well

iirc, lithium ponds can range in a bunch of different colors (and can also differ in colors based on purity and also how concentrated the evaporation pools are)
