Stones cut flat for evaporating seawater to extract salt, Yangpu Ancient Salt Field. Yangpu Field is an archeological heritage site in Yantian village, on Yangpu Peninsula, Hainan, China. The area, established around 800 AD, comprises more than 1,000 stones, cut flat on top, used to evaporate seawater to produce salt. The stones have a thin rim around the edge to contain the water. During high tide, the surface of the stones fill with water. During low tide, the seawater evaporates, leaving the salt, which is then collected. Caption and Photo source: ©© Wikipedia
Excerpts;
A clear change in salinity has been detected in the world’s oceans, signalling shifts and an acceleration in the global rainfall and evaporation cycle.
Salinity shifts in the ocean confirm climate and the global water cycle have changed…
