A
Clemson University paper looked at the environmental impact of latex balloon releases, and the picture it paints is far from a natural material quickly breaking down into harmless pieces.
The study used tracking and video methods to see what happened when balloons were released during sporting events, and the researchers discovered that
only 12 percent of balloons fell to Earth in the tiny pieces that the balloon industry talks about. In fact, 81 percent of the balloons that researchers recovered were half-intact.
The other interesting aspect of balloon releases this study discovered is that balloons aren’t the only piece of litter at play here. The strings, often not made from biodegradable materials, can do a lot of damage when animals ingest them.
They also found that sea turtles and shore birds are both harmed when they ingest latex.
