In the 1900s a simpler world counted just 1.6 billion people; by the 2000s we hit six billion. Today, with the global population projected to crest at 9.4 billion, we’re already scrambling for resources. One in eight people lack enough food, and over a billion still live without reliable electricity. These pressures expose a list of unexpected things the world is running out of – from the sand beneath our feet to the nurses caring for our elders.
Why These Unexpected Things Matter
10 Sand
It may sound absurd, but sand is disappearing fast. This gritty grain isn’t just for deserts; it’s a core ingredient in concrete, glass, and asphalt – even the toothpaste you squeeze each morning. Aggregate (sand and gravel) accounts for about 85 % of all mining activity, and the rate of extraction far outpaces natural replenishment.
China alone has consumed more sand in the past four years than the United States did throughout the entire 20th century. India wrestles with a “sand mafia,” and Dubai, despite being surrounded by dunes, imported sand from Australia to erect the Burj Khalifa.
9 Effective Gonorrhea Treatments
The first antibiotics to fight gonorrhea appeared in the 1940s, but the bacterium has a knack for mutating and dodging our drug arsenal. In just seven decades, most antibiotics have lost their punch, leaving only a single class still reliably effective.
The inaugural case of drug‑resistant gonorrhea surfaced in Japan in 2011. Since gonorrhea is the world’s most common sexually transmitted infection and half of infected women are unaware they have it, the resistant strains have a massive window to spread. Bottom line: practice caution in the sack.
8 Helium
Say goodbye to party balloons – helium is on the brink. Beyond festive lifts, this non‑renewable gas cools superconducting magnets in MRI machines, aids leak detection in high‑pressure containers, and enables scientists to reach the lowest temperatures for quantum‑mechanics experiments.
Because helium’s unique properties can’t be substituted, we may eventually have to mine it from the Moon if current reserves aren’t rationed wisely.
7 Lethal Injection Drugs
These drugs aren’t vanishing due to a raw material shortage; pharmaceutical firms simply don’t want their names linked to executions. In 2016, Pfizer joined roughly 20 other American and European companies in blocking U.S. states from using their products for lethal injections.
States that still permit the death penalty are now scrambling for the “juice.” Imported supplies from countries that still produce them are frequently seized by federal agents, making restocking virtually impossible.
6 Dirt
Scientists estimate we have roughly 60 years of topsoil left. Repetitive farming of the same crops leaches nutrients, rendering soil barren. With the global population projected to boost food demand by 50 % over the next two to five decades, we’ll also produce about 30 % less food in that span.
And water won’t save us: a recent study shows that nearly half of sea‑level rise since 1960 stems from irrigation runoff spilling into the oceans.
5 Sperm
A sweeping analysis revealed that between 1973 and 2011, sperm concentration and total count dropped by 52.4 % across North America, Europe, Australia, and New Zealand. Declining sperm health isn’t just a reproductive concern; it correlates with broader morbidity and mortality.
Why the plunge? Researchers point to endocrine‑disrupting chemicals, poor diets, rising body‑mass indexes, heightened stress, and increasing pesticide residues in food. As these pressures mount, sperm counts are likely to keep falling.
4 Fish
Fishing at current rates could empty the oceans. Global catch is dropping by about 2 % each year, and many large fisheries dramatically underreport their hauls to the FAO.
Wealthier nations’ fleets frequently fish illegally in poorer countries’ waters, chasing profits to feed seven billion people at a pace the sea cannot replenish. Approximately 92 % of catches from Chinese fleets go unreported, and 40 % of global fishing is kept secret. Once the fish vanish, the already‑imbalanced marine food web will spiral further out of whack.
3 Data Storage
Data isn’t just a buzzword; it’s a critical asset for businesses worldwide. By 2020, an estimated 26 billion connected devices will be online, not counting roughly seven billion smartphones, PCs, and tablets. Existing silicon‑based hard drives are straining to keep pace.
In 2013, researchers at the European Bioinformatics Institute packed Shakespeare’s sonnets, the original DNA double‑helix paper, a 26‑second clip of Martin Luther King Jr.’s “I Have a Dream,” a compression algorithm text file, and a JPEG into a single DNA strand. If we can harness such ingenuity, the storage crunch may be solvable.
2 Gold
While sand mining booms, new gold discoveries have stalled. Over the past decade, mining firms have faced project cancellations due to heightened risk. Investment in gold fell from $10 billion in 2012 to just $4 billion in 2016, and supply is projected to dip 15‑20 % in the next three to four years.
The silver lining? Space may hold the answer. Asteroid 2011 UW158, which passed Earth in 2015, spans over 500 meters and is estimated to contain between $300 billion and $5 trillion worth of precious metals. Though it lies six times farther than the Moon, companies like Planetary Resources are already testing extraterrestrial prospecting, and the European Space Agency’s Rosetta mission proved landing on a comet is feasible – hinting at a future interplanetary gold rush.
1 Nurses
Several forces are driving a looming nursing shortage. Between 2010 and 2030, the U.S. senior‑citizen population will swell by 75 % to 69 million – one in five Americans will be a senior. Meanwhile, 80 % of older adults have at least one chronic condition, and 68 % have two.
Why are nurses dwindling? In 2012, nursing schools turned away 79,659 qualified applicants because of insufficient faculty, clinical sites, classroom space, and preceptors, coupled with budget constraints. Adding to the strain, the current nursing workforce is aging and gradually retiring, threatening a severe healthcare deficit unless more nurses are trained and retained.
