2 . Ecuador may have a new tourism jingle, but people there don’t want anyone to actually sing it. Indeed, the country’s latest national park is built on the belief that silence is golden. The South American country has become the first in the world to build a “quiet park” across the Zabalo River where silence is protected like a natural resource.
There are no transport routes here or residential and commercial developments. You can’t even hear the sound of power lines.
Named as Wilderness Quiet Park, the land is owned by the Cofán people of Ecuador. But hopes are high that the unique space in the world increasingly affected by noise will start tourism in the region — quiet tourism, that is.
These days, it’s almost impossible to escape the human noise. And it’s a serious effect on the health of animals and humans. “Science has made it clear that noise pollution is not just an annoyance, it causes health risk and impacts wildlife’s ability to survive.” By recognizing the Zabalo River as the world’s first “quiet park”, we are paving the way for many more such parks around the globe,” says Gordon Hempton, an ecologist and co-founder of Quiet Parks International, an organization which aims to spread quiet across the globe.
So, what’s it actually like when nature is the only soundtrack? Here’s how Sam Goldman, a journalist, describes “The monkeys roar; insects buzz; and birdsong cackles...”
But the park not only gives nature a chance to find its voice. The people who own the land — the Cofán people — have long regarded themselves as caretakers of the rivers and rainforests in the region but their numbers have decreased to fewer than 2,000. Quiet Parks International will help the Cofán people “defend their lands and preserve their culture”.
