UNESCO World Heritage Sites

The Great Barrier Reef, the Galapagos Island, the Great Wall of China: These are all geographic treasures, internationally recognized by UNESCO as World Heritage Sites. Washington State has one: the Olympic National Park. A nonprofit in Canada is now petitioning its federal government to add the Salish Sea to that list.                       

On a recent fall morning, a large crowd clogged the steps at one of Venice's main tourist sites, the Rialto Bridge. But on this day, there was a twist: it was filled with Venetians, not tourists.

"People are cheering and holding their carts in the air," says Giovanni Claudio Di Giorgio, who helped organize the march with a grass-roots organization called Generazione '90.

The carts he refers to are small shopping carts — the symbol of a true Venetian.
