Il teatro dell’opera e l’Harbour Bridge di Sydney sono piombati nell’oscurità sabato per dare il via all’”ora della Terra”. La campagna è organizzata ogni anno dal WWF nel mondo intero per sensibilizzare sugli effetti dei cambiamenti climatici e per promuovere la salvaguardia della natura.
L’”Earth Hour” (il nome originale in inglese), iniziata proprio in Australia nel 2007, viene osservata in 187 paesi da milioni di persone che dalle 20.30 alle 21.30 locali spengono le luci. Anche molteplici città aderiscono all’iniziativa.
In Svizzera vi partecipano diversi comuni. I castelli di Valère e Tourbillon di Sion, l’abbazia di San Gallo e i catelli di Bellinzona sono alcuni dei monumenti che si spegneranno questo sabato sera.
All’estero a rimanere senza corrente saranno fra gli altri l’Empire State Building, il Taj Mahal, la Porta di Brandeburgo e la Tour Eiffel.
