On le pense infini, il est banal, partout autour de nous: le sable. Le troisi\u00e8me rapport du Programme des Nations unies pour l\u02b9environnement vient de sortir et il rappelle une r\u00e9alit\u00e9 ignor\u00e9e: le sable n\u02b9est pas renouvelable. Il met des mill\u00e9naires \u00e0 se former, alors que nous en consommons 50 milliards de tonnes par an. Cette surexploitation provoque p\u00e9nuries, \u00e9rosion, destructions d\u02b9\u00e9cosyst\u00e8mes et tensions sociales. La demande pour la construction pourrait augmenter de 45% d’ici 2060. Faut\u2011il continuer \u00e0 b\u00e2tir ou pr\u00e9server nos \u00e9cosyst\u00e8mes? <\/p>\n
