What happens when they run out of salt? All the salt they put on the roads must end up back in the lakes but not in a way that is as easy to extract, right?
"According to the Werra Potash Mining Museum in Heringen, Monte Kali has been in operation since 1976; as of August 2016, it covered 98 hectares (240 acres) and contained approximately 201 million tonnes of salt, with another 900 tonnes being added every hour and 7.2 million tonnes a year."
I mean, you could sell salt ffs why just dump it? And what happens when it rains, surely it's absolutely fucking that soil for years to come
You can always extract it form the sea by mere evaporation like our ancestors did. Plus salt deposits in the ground all over the world are massive, we had salty seas for billions of years.
