Can we save the climate with raw materials from the sea?

Berlin Casper has an impressive patience. The almost transparent species of octopus incubates its offspring for up to four years. And that in a hostile environment, around 4000 meters below the sea surface. No ray of sunshine penetrates up to here, the pressure is unbelievable – 400 kilos weigh on every square centimetre.

Unfortunately, when caring for the brood, the octopus alights on a mineral aggregate that another terrestrial species considers a valuable treasure. People discovered the so-called manganese nodules at the bottom of the sea as raw material deposits. In addition to manganese, the accumulations also contain nickel and cobalt – all important materials for electric cars or photovoltaic systems.
