We all know that litter is a problem around the world. Although this won't solve it, every piece kept out of the wild helps. Amazon currently has a category labeled - Balloons for release. https://www.amazon.com/biodegradable-balloons-release/s?k=biodegradable+balloons+for+release  These are made of Latex. and even though they will eventually degrade, it can take up o 6 years for them to do so. This also does not take into account any ribbon or string that is tied to them. https://balloonsblow.org/latex-balloons-still-kill/​   https://www.imas.utas.edu.au/news/news-items/new-study-finds-latex-balloons-are-not-biodegradable  

This is not a hard problem for Amazon to correct.

1- Remove this category in the search.

2- Block companies that advertise latex balloons "For Release"  "Bio-degradable" "Balloons for launching".

3. Header or notice on all balloon section and sales that releasing balloons is a danger to wildlife and litters the environment.
