C'est pas sorcier - Season 1 Episode 273 L'eau en danger
Parce qu'elle coule à flot, on a tendance à oublier que l'eau est un bien précieux. Dans les pays industrialisés, la qualité de l'eau douce se dégrade. Les eaux de surface et - en sous-sol - celles des nappes phréatiques, sont de plus en plus polluées. Fred, Jamy et Sabine sont partis à la rencontre d'éleveurs et d'agriculteurs bretons pour essayer de comprendre comment on en est arrivé là. Entre nitrates, pesticides et phosphates, ils nous exposent les solutions qui pourraient enrayer cette tendance. Quel circuit l'eau potable suit-elle avant d'arriver à notre robinet ? D’où viennent les nitrates qui sont entraînés vers les rivières et les nappes phréatiques ? Quelles mesures sanitaires permettent de contrôler leur présence dans l'eau et dans les légumes que nous consommons ? Quelles parades a-t-on trouvées pour éviter le ruissellement des pesticides ? Comment débarrasse-t-on l'eau des nitrates, pesticides et bactéries en tous genres ?
