The Independent: "A ballooning problem: the great helium shortage"

"The supply of helium, an inert element with the lowest boiling point of any known substance, has now become so erratic that scientists are calling for a ban on all but the most essential uses – which could mean no more helium-filled party balloons. "Peter Wothers of Cambridge University, who gave the 2012 Royal Institution Christmas lectures, said:
“The scarcity of helium is a really serious issue. I can imagine that in 50 years’ time, our children will be saying: ‘I can’t believe they used such a precious material to fill balloons'.

There is a finite supply of this lighter-than-air gas on Earth, so if we keep using it for non-essential things like party balloons, where we’re just letting it float off into space, we could be in for some serious problems in around 30 to 50 years’ time."
