Atlantropa was a huge construction and colonization idea produced by the German architect Herman Sörgel in the 1920s. He intended to connect the continents of Europe and Africa throughout the partial evaporation of the Mediterranean Sea (drain 1/5 of the Mediterranean sea), allowing millions of Europeans to get a new life in what would become the Eurafrican supercontinent (Atlantropa). The new supercontinent would provide food for 150 million people. The idea was caused by the then-new understanding of the Messinian salinity crisis , a pan-Mediterranean geological event that took place 5- 6 million years ago. The basin of the Mediterranean Sea is hydrologically deficient, which means that it loses water by evaporation rather than gains by the supplying of rivers. Its primary object was a hydroelectric barrier to be built crossed the Strait of Gibraltar, which would have produced enormous amounts of hydroelectricity (365.000MW) and would have led to the lowering of the surface of t...
