E' una situazione preoccupante quella che risulta dal rapporto sullo stato della biodiversità in Svizzera pubblicato mercoledì dall'Ufficio federale dell'ambiente. La metà degli habitat presi in esame e più di un terzo delle specie animali e vegetali sono infatti minacciati.
Ne sono responsabili lo sfruttamento del suolo e delle acque, dovuto alla pressione esercitata dall'agricoltura e dagli insediamenti urbani, l'inquinamento da azoto e i mutamenti climatici.
Una tendenza -si fa notare- che rischia di compromettere anche la qualità della vita umana, la prosperità economica e l'unicità dei paesaggi elvetici. Non è quindi più solo una questione di etica.
