C'est pas sorcier - Season 1 Episode 383 Le sable : les sorciers veillent au grain
Sabine et Jamy ont suivi le grand voyage des grains de sable. Entre deux leçons de géologie, ils nous expliquent pourquoi beaucoup des plages françaises sont aujourd'hui menacées de disparition. Postés sur la côte atlantique, ils décortiquent pour nous les minuscules grains de quartz, de grenat, de mica et d'olivine qui composent le sable et retracent leur histoire. Nous découvrons avec eux le problème épineux du recul du littoral et les mesures de protection qui sont prises aujourd'hui. Pourquoi la moitié de nos plages subit-elle ce phénomène d'érosion? Quelle part l'activité humaine occupe-t-elle dans ce scénario ? Les solutions actuellement mises en oeuvre sont-elles réellement efficaces ?
