Haute-Savoie is dotted with large altitude lakes that create unique panoramas. Fragile ecosystems, watched carefully by a local child : hydrobiologist Grégory Tourreau. For the first time, he analyzes the purity of the waters of Lac Vert, a wonder with emerald reflections, threatened by microplastics.
Extract from the show “Roots and wings : The taste of Haute-Savoie” broadcast on wednesday 05/02/2020 on France 3 and France.tv
