HOW A DROPPED BAG OF CHEETOS HAD ‘WORLD CHANGING’ IMPACT ON LIFE IN A CAVE

After a visitor dropped the snack in Carlsbad Caverns, the “foreign detritus”
sparked mold and microbial growth that disturbed the delicate ecosystem, the
park said.

When a recent visitor to Carlsbad Caverns National Park in New Mexico dropped a
bag of Cheetos inside one of the caves, losing a snack was probably an
inconvenience. But to the tiny microorganisms who call the cave home, the food
can be a “world changing” force, park officials stressed in a post on social
media last week.

answers based on our published reporting.


The processed corn in the Cheetos, softened by the humidity of the cave, created
“the perfect environment to host microbial life and fungi,” park officials
wrote.

“Cave crickets, mites, spiders and flies soon organize into a temporary food
web, dispersing the [Cheetos’] nutrients to the surrounding cave and
formations,” they continued. “Molds spread higher up the nearby surfaces, fruit,
die and stink. And the cycle continues.”

Some members of this “fleeting ecosystem” are cave dwellers, but many are not,
disrupting the cave’s delicately balanced ecosystem, officials said. “At the
scale of human perspective, a spilled snack bag may seem trivial, but to the
life of the cave it can be world changing,” they wrote.

Andy Baker, a professor of biological, earth and environmental sciences at
Australia’s University of New South Wales Sydney, echoed the sentiment, writing
in an email that: “One way to think about it is that caves are quite extreme
places to survive in the scheme of things. There’s no light. Water can be
limited. Nutrients are in short supply.”

“So the critters that live in caves have adapted to that environment,” he
continued. “Add food of any kind, and that could disrupt the balance of the cave
ecosystem.”

Park rangers spent 20 minutes meticulously removing the foreign detritus and
molds from the cave surfaces, park officials said, emphasizing that dropping a
full snack bag off-trail inside the cave is “completely avoidable.”



Carlsbad Caverns National Park, the site of North America’s largest single cave
chamber by volume, hosted close to 400,000 visitors last year, contributing
nearly $32 million to the local economy, according to a recent report.

While park rules prohibit visitors from consuming anything but “plain water” in
the caverns, that hasn’t stopped hungry tourists from snacking. And the park has
struggled with visitors breaking rules before. At least 60,000 cave formations
have been broken off, many probably by tourists to take home as illegal
souvenirs, officials said in August.

Jut Wynne, an assistant research professor of biological sciences at Northern
Arizona University, said in an email that park officials should also consider
mandating special shoes and prohibiting visits during ecologically sensitive
times of the year.

“A lot of folks today treat national parks like theme parks. Park officials have
used the Cheetos mishap to stress, in a fun and accessible manner, how human
actions are altering the natural world,” Wynne wrote. “Careless behavior in our
natural wonders have consequences.”

The National Park Service promotes “Leave No Trace” messaging, urging visitors
to minimize what they leave behind. “A common saying is to take only photographs
and leave only footprints,” Carlsbad Caverns National Park said on social media
last month.

While leaving behind some trace — such as the occasional piece of human hair or
textile that falls off clothing — is “impossible to prevent,” according to park
officials, the campaign encourages visitors to be conscientious about litter
they can control.

“Great or small we all leave an impact wherever we go,” Carlsbad Caverns
National Park officials said in last week’s post. “Let us all leave the world a
better place than we found it.”
