Unfortunately, balloons eventually fall to the ground, resulting in litter and possible health hazards to animals. The sap is collected through a tapping process similar to collecting maple syrup. Latex balloons are biodegradable when exposed to sunlight and the elements. However, depending upon where it lands, the balloon may take many months to decompose.
Paper is biodegradable, too, but discarding it improperly is littering and is illegal.
Releasing balloons in the air is no different. After floating for awhile, the balloon will eventually return to the Earth, where it becomes litter. Impacts on Wildlife and the Environment Releasing balloons may seem like a harmless activity. However, the litter caused by balloons has a significant impact on the environment. Think of all the occasions, in addition to sporting events, where people release balloons weddings, parades, holidays, community festivals and celebrations.
