Sure, fewer party balloons and squeaky-voice clown pranks would be a shame. But recent reports of a worldwide shortage of helium could also create supply problems in the production of some of the most advanced technologies, reports Quebec news site Le Soleil.

Reserves of helium, a non-renewable resource that is abundant in nature but hard to capture, is found mainly in the U.S., especially in Texas, where it is stored as a byproduct of natural gas production.

In the early 20th century, as helium was considered critical to American defense, the U.S. government created a national helium reserve, and the U.S. still has one-third of the world’s entire stock, notes Smithsonian Magazine.

But in 1996, Congress mandated that the reserve be sold down and private companies haven't taken up the slack, and “consumers are left with spiking prices and tightening supplies,” reports Popular Mechanics.

Helium is necessary not only for its well-known properties of keeping party balloons afloat and causing funny voices. It is critical to the functioning of superconductors, particle accelerators, magnetic resonance imaging (MRI), welding, weather balloons and fiber optics, among many other scientific and health uses.

According to the Guardian, a single helium party balloon should cost 75 pounds ($122 dollars) if it were priced to reflect the scarcity of helium. Some scientists have called for a reduction or ban in the use of helium balloons. Cornell University professor Robert Richardson, who won a Nobel prize studying helium, is leading the efforts. “We are squandering an irreplaceable resource,” Richardson says.

If the stock continues to deplete, here's some of what you might miss:

How South American Oceans Can Sway The U.S.-China Showdown

As global rivalries and over-fishing impact the seas around South America, countries there must find a common strategy to protect their maritime backyards.

BUENOS AIRES — As the U.S.-China rivalry gathers pace, oceans matter more than ever. This is evident just looking at the declarations and initiatives enacted concerning the Indian and Pacific oceans.

Yet there is very little debate in South America on the Sino-American confrontation and its impact on seas around South America, specifically the South-Eastern Pacific (SEP) and South-Western Atlantic (SWA). These have long ceased to be empty spaces — and their importance to the world's superpowers can only grow.

Central to the tragic absurdity of this war is the question of language. Vladimir Putin has repeated that protecting ethnic Russians and the Russian-speaking populations of Ukraine was a driving motivation for his invasion.

Yet one month on, a quick look at the map shows that many of the worst-hit cities are those where Russian is the predominant language: Kharkiv, Odesa, Kherson.
