Un gregge di capre è stato cooptato nella periferia di Los Angeles contro gli incendi che, anche recentemente, hanno colpito vaste aree della California. La scelta si è rivelata un'ottima soluzione. Mangiando la vegetazione, questi animali creano delle "zone cuscinetto", che da un lato impediscono agli incendi di diffondersi e dall'altro forniscono ai vigili del fuoco (quelli umani) dei "corridoi" liberi per combattere le fiamme.
"Abbiamo scoperto che sono veramente efficienti per lo scopo", ha spiegato ad AFP Jeffrey Ragusa, pompiere di Glendale.
"Le capre sono molto leggere rispetto ad altre soluzioni - aggiunge Alissa Cope, direttrice del Sage Environmental group, che collabora al progetto - Questo permette anche di evitare problemi di erosione del suolo".
"Questa è una zona molto impervia - continua Cope - Molti arbusti secchi andrebbero estirpati e trasportati a mano. Ma grazie alle capre... loro li mangiano e... spariti. Non esistono più".
