"It's because there is less boat traffic that usually brings sediment to the top of the water's surface."

Italy's lockdown due to the coronavirus pandemic is not only keeping people safe, but it's giving the outdoors — which is typically flooded with tourists — a chance to recharge.

In photos posted to a Twitter account and Facebook group, “Venezia Pulita” which translates to "Clean Venice," locals are sharing pictures of the city’s water looking impossibly clean.

The phenomenon, however, is not due to a decrease in pollution.

"The water now looks clearer because there is less traffic on the canals, allowing the sediment to stay at the bottom," a spokesperson for the Venice mayor’s office told CNN. "It's because there is less boat traffic that usually brings sediment to the top of the water's surface."

While the city’s water may not have suddenly become cleaner without constant visitation, the air quality has also certainly improved. With fewer water taxis and boats ferrying the city’s tourists and residents along the canals, the air has become cleaner, the spokesperson said.

Venice shut down in February in the last days of its annual Carnival celebration when the coronavirus hit Italy and has become the epicenter of the outbreak with over 30,000 cases.

Some social media users are hoping that the coronavirus shutdown could act as an “ecological reset” for the world’s busiest cities.
