I grandi carnivori stanno tornando a popolare tutta l'Europa. Si tratta i orsi bruni, lupi, linci e ghiottoni, che occupano, ovunque nel Vecchio Continente, gli spazi lasciati liberi dal trasferimento progressivo della popolazione nelle città.
A farne il censimento è stato un gruppo internazionale di ricercatori coordinato dall'Università di Riddarhyttan, in Svezia. Il lavoro, che è durato due anni e ha coinvolto 26 paesi, ha rilevato che le quattro specie sono in crescita e che un terzo del territorio ne ospita almeno una.
La tendenza, per gli specialisti, è positiva, poiché la loro presenza garantisce una migliore completezza degli ecosistemi. Anche in un continente popolato, malgrado i conflitti con gli allevatori, si può quindi coesistere con i grandi predatori e non è necessario concentrarli in aree protette.
