Science-y stuff

Not to suggest that the air in China isn't disgusting, kinda like the air in L.A., but...

I'd like to point out that throughout Asia, because of the close proximity in which people exist, it is not only common, but indeed expected, that when one is ill, like with a cold, the person who is ill will wear a mask such as the one in the image, so as to minimize the spread of the infection.

Here in the west, we scoff at such things as silly...

And all too often, the western media mistakes the wearing of a mask as a testament of air quality. Completely passing up images of oxygen vending machines in convenience stores and subway stations. Like this one...

 

Ummmmmmmmmmm.......

Wow thank you for the daily photo link...

 

Great pics every day. I have APOD set as my homepage so it's the first thing I see when I fire up the browser. Always interesting, frequently spectacular.

Beneath the info paragraph you can use the left arrow to step back day by day.
There's a searchable archive too - hours of fun.

This has been an issue for well over 15 years.
Helium deposits are found as a byproduct of mining Uranium, and it can not easily be manufactured.
In the early 2000's when I was an active SCUBA diver, tech divers (as well as welders) were concerned about price and availability of Helium.

Seriously... party and parade balloons are a complete waste of this valuable resource. Likely a small percentage compared to manufacturing uses, but still, like atmospheric pollution and the use of other resources, every little bit makes a difference.

Scarcity is certainly nothing new. The Hindenburg was actually designed for helium - it was refitted for hydrogen instead because the US had a virtual monopoly and wouldn't sell helium in case it might be used for military purposes.
