# The Hidden Environmental Consequences of Balloons
Written on
Chapter 1: The Dark Side of Balloons
Recently, while out for a walk, I spotted two colorful balloons floating along the roadside, swaying in the breeze. The sight made me uneasy.
Balloons are often associated with celebrations—birthdays, weddings, and graduations—but their aftermath can be troubling. Over the past 25 years, coastal cleanups across more than 150 countries have documented over 1.2 million balloons washed ashore. In 2017 alone, these cleanups revealed enough balloons to lift 17.5 superheroes into the sky.
Section 1.1: The Balloon Industry's Growth
As of 2021, the global market for party balloons was valued at around $1.48 billion, projected to rise to approximately $1.96 billion by 2028. The demand for balloons continues to surge, particularly for events like baby showers, birthdays, and corporate gatherings. Yet, what happens to these balloons once the festivities conclude?
Section 1.2: The Role of Plastics
Plastic has become an integral part of modern life, utilized for its affordability and versatility in various sectors, including construction and food packaging. Since the 1950s, plastic production has skyrocketed nearly 230-fold, reaching 460 million tons in 2019. Alarmingly, about a quarter of global plastic waste is either poorly managed or discarded improperly, with around 0.5% ending up in oceans.
Plastic pollution in marine environments poses a significant threat, particularly to seabirds that may mistake floating debris for food. Predictions indicate that by 2050, nearly all seabird species will have ingested some form of marine debris.
Marine debris is defined as any persistent, solid material that is either intentionally or unintentionally discarded into marine environments, including the Great Lakes.
Chapter 2: Balloons as Marine Debris
Balloons, when released into the environment, can ascend to heights of around 8 kilometers, where they eventually break apart into long, thin strands.
Research from the University of Tasmania indicates that balloons pose the highest mortality risk among marine debris for seabirds. The likelihood of a seabird dying from ingesting a balloon or its fragments is 32 times greater than from ingesting hard plastic.
The primary cause of death is often a blockage in the gastrointestinal tract, which includes organs responsible for digestion and waste excretion. While soft plastics make up only 5% of ingested items, they account for over 40% of known or suspected mortalities.
Procellariiformes, a group of seabirds that includes albatrosses and shearwaters, are particularly at risk. These birds primarily feed on epipelagic fish, squid, and crustaceans. A 2016 study along the Australian coast found that short-tailed shearwaters had ingested 82% of all balloons documented in deceased birds. Notably, 54% of these balloon fragments were red or pink, while 32% were orange—colors that likely resemble their natural prey.
Balloons also pose considerable threats to marine mammals and turtles. An examination of deceased sea turtles revealed that balloons or their fragments made up 78% of the rubber found in their stomach contents.
Section 2.1: The Myth of Biodegradable Balloons
The balloon industry often claims that latex balloons are biodegradable. Biodegradability refers to the ability of a substance to decompose naturally without harming the environment. While natural rubber latex is derived from more than 2,000 plant species, its degradation is a slow process that can take several years.
Moreover, natural latex is treated with substances like ammonia and TMTD to prevent bacterial decay. This treatment can contribute to air pollution and create harmful nitrosamines. The production of latex balloons also involves various additives, such as artificial dyes and plasticizers, complicating the prediction of their biodegradability.
Latex balloons, under certain conditions, can behave similarly to plastic in the environment, failing to decompose uniformly.
Section 2.2: The Environmental Impact of Mylar Balloons
Mylar balloons, made from a type of polymer known as BoPET, have gained popularity for their durability and ability to retain helium. However, they also contribute to environmental issues and can cause power outages when they come into contact with electrical infrastructure.
Wrapping Up
The environmental ramifications of balloons are significant and cannot be overlooked. The next time you see a balloon, consider its potential impact on our planet. Celebrations can still be enjoyable without balloons. It’s crucial for us to rethink our choices and seek sustainable alternatives. As consumers, we hold the power to address many global challenges simply by being mindful of our purchases and waste disposal practices.
