Raw materials from the deep sea are essential to fighting climate protection

Berlin Casper has impressive patience. Semi-transparent octopus species incubate their offspring for up to four years. And that in a hostile environment, about 4,000 meters below sea level. Not a single ray of sunlight penetrates even here, and the pressure is incredible – it weighs 400 kilograms on every square centimeter.

Unfortunately, when tending to a brood, the octopus stumbles upon a metal block that other terrestrial species consider a valuable treasure. People have discovered so-called manganese nodules on the sea floor as deposits of raw materials. In addition to manganese, the accretion also contains nickel and cobalt – all important materials for electric vehicles or photovoltaic systems.
