Up, up and away

Balloons can be a real menace, and not just those that may have been deployed by China to spy on the United States. Even the child-size pink plastic “Happy Birthday” balloon can be hazardous if left in the wrong hands. Or, more precisely, left from the wrong hands.

That’s because many of these innocuous party favors are filled with helium for loft and then released, either intentionally or by accident, to float gracefully away. Which they do — until they deflate and return to Earth, coming to rest in a bush or tree or plopping down into the ocean, where they may cross the path of some unfortunate sea creature.

Sadly, this is not a rare occurrence. There are several recent cases of sea turtles, seals and sea lions off the California coast discovered entangled in or choked by balloon strings, or in physical distress after ingesting balloons. Among the key findings of a 2020 Oceana report on ocean plastic was that balloons were one of the most common types of plastics entangling or consumed by marine life, along with bags, recreational fishing line, sheeting and food wrappers.

The threat to sea life is one of the main reasons a handful of coastal Southern California cities have slapped restrictions on the use of balloons, ranging from prohibiting the sale or release of lighterthan-air balloons (which generally means those filled with helium) to a ban on the sale, distribution or public use of all balloons passed by Laguna Beach.

If this trend sounds familiar, that’s because a few years back it was single-use plastic straws that were targeted by local bans. Eventually, there were so many different rules about distribution of plastic disposable straws that a statewide law, beginning in 2019, made sense. Balloons may be heading for the same fate.

It didn’t have to be like this. Balloons, like plastic straws, aren’t inherently bad. The problem is how humans use and thoughtlessly dispose of them. Releasing hundreds of colorful helium-filled balloons into the sky may be a visually stunning way to mark a notable occasion, but those airborne pieces of plastic will land somewhere and subsequently become a blight on the landscape and a hazard to the local wildlife. Some states, such as Hawaii, ban the intentional mass release of all helium-filled balloons.

California will phase out mylar balloons by 2031 because their metallic nylon foil shells have a tendency to cause blackouts and spark wildfires when they float into power lines. That’s good, but now California legislators should consider placing restrictions on the use and release of latex balloons. The balloon industry markets latex rubber balloons as biodegradable, but studies have found that they don’t break down in the ocean. Furthermore, the strings attached to balloons are generally plastic. This makes them single-use trash in the same way that grocery bags and straws are, and releasing them into the environment is littering.
