L'océan s'est dégradé au courant de nos vies, on peut le voir  par la diminution de la  taille moyenne des poissons. De fait, comme Daniel Pauly nous démontre à Mission Blue, chaque fois que la mesure de base baisse nous l'appelons la nouvelle "normale". A quel point nous arrêtons cet ajustement?

Daniel Pauly;: le changement de limite des oceans

People often believe the natural world they inherit is how it has always been, overlooking dramatic losses over time. In one lagoon, fish shrank to half their former size in a generation, yet locals accepted this as normal. The phenomenon, called shifting baseline, means that as ecosystems degrade, expectations quietly move downward. Without preserving history or creating protected areas, society risks accepting only remnants of what once existed.
