@MarkHoltom Balloon releases are like time-delayed littering. About the only good thing I could say about them is they're at least not Chinese lanterns, which can also add an element of time-delayed arson.
@MarkHoltom And there's a finite amount of helium. Wasting it on toy balloons is (also) criminal.

"latex balloons are often marketed as biodegradable because latex is a natural product, but the manufacturing process adds […] sulphur […] heavy metals, waxes, antioxidants, plasticizers, flame retardants & pigments"

"balloons were tested in freshwater, saltwater & industrial compost for 16-weeks […] there was no meaningful degradation."

Simply don’t release balloons!
Simple.

@MarkHoltom I wish fireworks would stop here too...July 4th and New Years terrify all of our animals! Plus the air fills with toxic smoke....
@MarkHoltom @MarkOnArt While it’s still important to not release balloons for many, many reasons, latex balloons do in fact biodegrade because latex is made from the sap of the rubber tree. Still can take a few years, still can gum up the animals, still ugly. But biodegradable.
@MarkHoltom ...Was this not banned in many places and should come with all balloons sold...
Why The Global Helium Shortage May Be The World’s Next Medical Crisis

Industry, tech, and medical professionals must work together to suggest feasible strategies to tackle this critical shortage. More efficient and judicious use of MRI will likely be needed in the future to ensure sustainability.
