Latex balloons are made from a natural product derived from trees found on farms in equatorial regions of the world. The harvest of latex is a completely natural process. The trees are “tapped” for the liquid, similar to the harvesting of syrup. The trees are not trimmed or chopped in any way, so there’s no risk of deforestation. 

Since latex is a 100% natural product, it will break down into a residue that is not harmful to the environment. Latex balloons biodegrade at about the same rate as other natural products, such as oak leaves and wood fibers.
 
The best approach? Composting!
It’s a fun and teachable activity for kids, and the resulting fertilizer can be used in the backyard.
 
Does this mean it’s OK to release latex balloons into the air?
No. While latex balloons are biodegradable, they should be properly disposed of in a composter.
