Africa-Press – Tchad. <\/strong><\/span>Ce sont les oce\u0301anographes qui ont sonne\u0301 l’alerte: a\u0300 la fin du sie\u0300cle, ils identifient dans l’oce\u0301an Pacifique une zone sature\u0301e en de\u0301bris plastiques de trois millions de kilome\u0300tres carre\u0301s. Mais ce \u00ab\u00a0septie\u0300me continent\u00a0\u00bb n’est que la partie e\u0301merge\u0301e de l’iceberg. \u00ab\u00a0Sur les 200 millions de tonnes de plastique qui se retrouvent aujourd’hui dans les oce\u0301ans, environ 80 millions sont dans l’eau et 117 millions dans les se\u0301diments marins. Seul 0,3 million flotte en surface\u00a0\u00bb, estime Jeroen Sonke, directeur de recherche CNRS a\u0300 l’Universite\u0301 de Toulouse 3.<\/p>\n

Une de\u0301gradation tre\u0300s lente<\/b><\/p>\n

\u00ab\u00a0Me\u0302me les bacte\u0301ries ne parviennent pas a\u0300 les dige\u0301rer\u00a0\u00bb, comple\u0300te Pascale Fabre, directrice de recherche a\u0300 l’Universite\u0301 de Montpellier et fondatrice du groupement de recherche Polyme\u0300res et Oce\u0301ans. Les plastiques les plus abondants sont les polye\u0301thyle\u0300nes et les polypropyle\u0300nes, issus de la transformation d’hydrocarbures.<\/p>\n

Comment agir ?<\/b><\/p>\n

\u00ab\u00a0Le paradoxe du plastique est qu’il dure tre\u0300s longtemps alors qu’on ne l’utilise parfois que quelques minutes, constate Pascale Fabre. Et il s’accumule: c’est cela, le principal danger.\u00a0\u00bb Les microplastiques avale\u0301s par les organismes marins – poissons, crustace\u0301s ou plancton -provoquent une inflammation de leur tube digestif. Une maladie qui porte un nom, la plasticose, depuis qu’une e\u0301quipe australienne l’a de\u0301crite chez des oiseaux marins, les puffins, souffrant de fibroses digestives pouvant alte\u0301rer la croissance et la survie de l’espe\u0300ce. Inge\u0301re\u0301es par les humains, ces mole\u0301cules pourraient induire des maladies inflammatoires du co\u0302lon et alte\u0301rer le microbiote intestinal. Encore peu e\u0301tudie\u0301s, les nanoplastiques, qui traversent les tissus et rejoignent la circulation sanguine, inquie\u0300tent encore davantage: ce pourrait e\u0302tre des perturbateurs endocriniens.<\/p>\n

Face a\u0300 cette catastrophe, comment agir ? \u00ab\u00a0La priorite\u0301 est de baisser notre production de plastiques – 10 milliards de tonnes depuis les anne\u0301es 1950 – puis de repenser leur conception en y inte\u0301grant une re\u0301flexion sur leur fin de vie , remarque Pascale Fabre. Certains plastiques recycle\u0301s sont en effet plus toxiques que leur version de de\u0301part, et ceux qui sont issus de matie\u0300re ve\u0301ge\u0301tale, comme l’amidon de mai\u0308s ou la canne a\u0300 sucre, ne sont pas toujours biode\u0301gradables dans la nature.\u00a0\u00bb Une re\u0301duction qui permettra de combattre un autre fle\u0301au: la quantite\u0301 de particules pre\u0301sentes sur les continents et dans l’atmosphe\u0300re, encore peu de\u0301battue, mais tout aussi importante et dangereuse que celle des oce\u0301ans.<\/p>\n
