    La Légine australe : un poisson méconnu

    Quel est le poisson le plus cher au monde? Le thon? Eh! bien, vous avez raison. Suite aux enchères qui se sont déroulées comme chaque année le 5 janvier au plus grand marché de poissons de Tsukiji à Tokyo au Japon, un thon rouge s’est vendu à un montant encore jamais égalé.

    Un prix sur leur tête?

    L’épisode Mission Biodiversité diffusé à l’émission Découverte nous dévoilait la cohabitation difficile entre les humains et les jaguars au Costa Rica. Le sourire des braconniers avec la tête d’un jaguar entre les mains est calqué dans ma mémoire. Depuis, des centaines de jeunes élèves du primaire et du secondaire veulent connaître la suite de l’histoire.

    Du harpon à la caméra

    Le chasseur se réveille avant le lever de soleil, sur une mer calme. Bien, il sera plus facile de repérer les grands souffles au large.

    La décision d’un tribunal international qui interdisait au Japon de poursuivre cette campagne de chasse dite « scientifique » était une grande victoire.

    Anticosti – pas de fumée sans feu

    Le raccourci intellectuel et la mathématique déficiente

    Le Québec se meurt de trouver du pétrole, de le faire circuler sur son territoire, de l’envoyer par bateau et de se graisser la patte au passage. 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.
