Balloons and the Environment

Latex balloons are made of 100% natural, biodegradable latex.
The harvest of the sap from the rubber trees discourages de-forestation and the latex-producing trees are left intact allowing them to continue producing latex for up to 40 years
Latex balloons biodegrade in about the same time as an oak leaf
During a balloon release, the majority of balloons will rise to an altitude of approximately 5 miles. At the altitude, the balloon will either freeze and become brittle or explode due decreased air pressure and the helium expanding. This means that the balloon is reduced to pieces of natural rubber about the size of a penny which fall back to earth where they finish decomposing naturally.
Studies have shown that latex balloons ingested by animals pass through the digestive system.
Balloons should NEVER be released with anything more than a race card (if applicable). Strings, ribbon, valves, sealing discs and clips are non-biodegradable and may harm wildlife.
Balloons should be hand-tied and released individually (NEVER tied together in bunches)
Foil balloons and latex balloons with metallic pigment should never be released into the environment.
