#mcd (Must Come Down) – A Citizen Science Project

mcd_ballonHelium balloons pose a unique threat to wildlife and the environment. When released outdoors, the balloons eventually shatter and/or fall to earth, where the latex fragments are often mistaken by wildlife as food, or individuals become entangled in the strings or latex, leading to stress, injury, malnutrition, and sometimes death. What differentiates balloons from other garbage and debris, however, is that the very nature of their being – that they are filled with a gas lighter than air – not only allows them to stay airborne and disperse farther distances from their point of origin than might otherwise occur with a discarded straw or plastic bag, but also disperse to higher altitudes where latex balloons undergo an explosive “brittle fracture” that results in both large and micro material that fall to earth, making it difficult to track their fate.

As one who spends time outdoors, the number of spent balloons I’ve found littering my favorite open spaces has left me with a bitter taste in my mouth. If you throw a plastic grocery bag on the ground, there are few among us who would dispute that the very act constitutes littering. So what makes balloons any different?

2-iphone-rightTo better understand – and to help educate the public – about the fate of air- or helium-filled latex and mylar (foil) balloons released outdoors, and the inevitable fact that when balloons are released, singly or en masse, they must eventually fall to earth, I have started #mcd (Must Come Down;, a citizen science project whose purpose is to collect geotagged data on balloon trash through the app Litterati. Here’s how it works:

Once you’ve downloaded the Litterati app (visit:, you can start logging your observations in three easy steps:

(1) Track it down!

Whether you are in an urban or open space (the woods, the beach, the desert, the city, or your backyard), keep an eye out for latex and mylar balloons.

(2) Tag it up!

Take a photo of any balloon you encounter with the Litterati app and tag it with #mcd, as well as #latexballoon or #mylarballoon.

(3) Pack it out!

Properly dispose of any garbage you collect.

As you collect and record balloon trash, you will be contributing to a growing open source database that will help future policy makers begin a meaningful dialogue about the consequences of balloon releases based on hard facts.

img_7737Although the balloon industry maintains that latex balloons are made out of natural latex and are, thus, biodegradable, it can still take 8-10 weeks when exposed to air and more than 5 months when submerged in water before a latex balloon degrades and breaks down. That leaves plenty of time for wildlife to ingest them.

Why do wildlife mistake balloons for food? On land and in water, balloon remains can resemble common prey or food types, like flower petals, fruit, or jellyfish. If biomimicry is the intentional design and production of materials and systems modeled on the natural environment, when inadvertent this process could be thought of as “apatobiomimicry”:




The inadvertent and deceptive resemblance of anthropomorphic materials, structures, and systems to biological entities and processes.

{from the Greek words apatē (ἀπάτη)/apatēlos (ἀπατηλός) meaning “deception”/”deceptive”, βίος (bios), life, and μίμησις (mīmēsis), imitation, from μιμεῖσθαι (mīmeisthai), to imitate, from μῖμος (mimos), actor.}

When balloons enter the natural environment, they become apatobiomimics: anthropomorphic materials that inadvertently and deceptively resemble biological entities or process. Among the species that are vulnerable to this bait and switch are marine birds and mammals, big horn sheep, and sea turtles and desert tortoises, many of which are threatened or endangered species. It’s true that what goes up, must come down – but when balloons fall to earth, the consequences can be fatal.
