La Légine australe : un poisson méconnuQuel est le poisson le plus cher au monde? Le thon? Eh! bien, vous avez raison.

On ne fait aucune exception sur la provenance et l’origine de l’or noir, sur ses méthodes d’extraction, sur le prix réel à payer pour s’enduire du produit responsable de la plus grande crise mondiale de l’ère moderne : les changements climatiques.
