The "He" being the chemical symbol for the gas Helium, used to fill party balloons the world over. There is currently a global shortage of helium. In recent months, the price of helium has risen significantly - three times this year, each time going up between eight and ten percent.
That means that you will have to pay more for the balloon you give your grandchild, or take to the hen party, or tie to the hospital bed. The balloon companies complain that rising prices mean people are buying fewer balloons for decorating their party venues.
But my question is - should we be buying these balloons in the first place?
They are 'single use plastic'
They float away - and a high percentage do escape their owners clutches, either accidentally, or as part of a 'balloon race' - and then clog up the oceans and hedges and endanger or kill animals, birds and fishes
Those two reasons alone ought to be enough to make us stop and think
But my question is - is this a reasonable use of a finite resource?
Helium is used for many other things - it is used in diving apparatus, it is used in rocket launches, it is used in the manufacture of computers, mobile phones, TV screens, in welding, in cryogenics, and for medical purposes.
Yes, Helium is used for a number of significant medical purposes
When I was taken ill in January, I had to have a brain scan. MRI scanners depend on helium, to keep their huge magnets cool. MRI scanners have revolutionised the diagnostic procedures in all branches of medicine.
Heliox is an oxygen/helium mixture which can be used to ventilate babies, children and adults with breathing difficulties. It is significant in the treatment of asthmatic patients.
So my question is - if the global supply of helium is limited, should we be pumping it into rainbow coloured plastic unicorn balloons - or ensuring that we keep more of it to help babies breathe, and to make faster diagnoses of cancer and other conditions?
David Cole-Hamilton, Emeritus Professor of Chemistry at the University of St Andrews, believes that given its importance in medicine, the use of helium for balloons should be banned. Given than the supply is limited, it is absurd that around 10% of this noble gas is used for party balloons. He says "If you said to people 'Do you want a helium balloon, or an MRI scan for your daughter?' it's an obvious choice"
I am inclined to agree with him.
