#Zinc, #plomb et #étain : l’extraction minière au prix «d’une culture de la mort»

Des milliers de mineurs boliviens travaillent dans la montagne du #CerroRico. Voleurs de minerais, éboulements, maladies... On y meurt souvent dans l’indifférence généralisée. Il y a une « culture de la mort », confient les veuves. https://reporterre.net/Zinc-plomb-et-etain-l-extraction-miniere-au-prix-d-une-culture-de-la-mort

🦂🧪 #Scorpions incorporate #metals like #zinc and #manganese into the tips of their stingers and the edges of their pincers.

This #biomineralization process makes their #anatomy more resistant to wear and breakage during #hunting. Scientists found that the specific placement of these #minerals depends on the physical needs of different scorpion species.

Metal-reinforced scorpions evolved to kill

Deadly pincers and tails make them nature's answer to cyborgs.
