In the discussion of non-renewable resources, petroleum is the big player, however, it is definitely not the only one. Earlier this year, the U.S. National Research Council predicted the world may run out of helium within as little as 40 years.
Helium on Earth is produced by the radioactive decay that occurs naturally in the Earth's crust. Shouldn't this mean the helium supply will replenish itself over time? Yes, but it would take an extremely long time. Consider that mankind has consumed millions, if not billions, of years worth of helium that built up in underground pockets. For the purpose of our foreseeable future, helium is a non-renewable resource on this planet.
Running out of helium would affect more than just birthday parties and blimps. Many types of scientific research equipment rely on the unique properties of liquid helium. Magnetic resonance imaging (MRI), a staple of modern medicine, also requires liquid helium. Helium also has roles in rocketry, welding, electronics production, and even food production.
The helium shortage needs to be brought into the public eye. Helium-free technologies need to be investigated before we run out of helium
