Alpine Ibex on Cingino Dam

"The ibex like to eat the moss and lichen off the stone, and lick the salt off the dam wall."

The Cingino Dam is in northern Italy, less than a mile from its border with Switzerland.

Back story here.

Do you know what's in the air you're breathing?

Have a look.

From the New York Times:

••••••••••••••••••••••••••••••

The monitor most intriguing local government environmental protection agencies and civilians alike is PurpleAir.

It hooks up outside, connects to WiFi, feeds into a global network and creates something like a guerrilla air quality monitoring network.

Adrian Dybwad, 49, the founder of PurpleAir, would watch the dust from a nearby gravel pit blow near his house in Draper, Utah, where he lives with his wife.

When the miners working there tried to expand it even closer, he decided he had to do something.

First he had to prove there was something wrong with the air.

"I said to myself, it's 2015, surely there must be a sensor that can tell me how much dust is in there," Mr. Dybwad said.

But nothing he could find was both cheap and accurate.

So he made his own.

Neighbors got interested.

Mr. Dybwad, who has a background in computer networking and surface-mount electronics, asked for donations and raised a few thousand dollars, and the community installed 80 sensors.

The amount of floating particles in the air (called particulate matter) was high, especially on windy days.

The closest government-run sensor was more than 10 miles away, and not picking up any of this.

As the community gathered with sensors, plans for the mine expansion vaporized.

In the last year, interest in the project has spiked.

Now he has more than 3,000 monitors reporting data every day.

He has built a map (top) to show what every PurpleAir around the world is reporting (green is good, red is bad).

Local government air quality monitoring groups are using the devices.

Since the California wildfires in November, Mr. Dybwad said, traffic has been up 10,000 percent.

In November, he moved production out of his backyard and into a new 2,200-square-foot workshop.

"You can't give the government control over monitoring and enforcement because then you can just monitor to the extent that you want to enforce," he said.

"Having this type of power in the public's hands, it gives a check on the government."
