The site was left untouched and largely unexamined for over a decade. A sign was placed to ensure future researchers could locate and study it.
16 years later, Janzen dispatched graduate student Timothy Treuer to look for the site where the food waste was dumped.
Treuer initially set out to locate the large placard that marked the plot — and failed.

"It's a huge sign, bright yellow lettering. We should have been able to see it," Treuer says. After wandering around for half an hour with no luck, he consulted Janzen, who gave him more detailed instructions on how to find the plot.
When he returned a week later and confirmed he was in the right place, Treuer was floored. Compared to the adjacent barren former pastureland, the site of the food waste deposit was "like night and day."

"It was just hard to believe that the only difference between the two areas was a bunch of orange peels. They look like completely different ecosystems," he explains.
The area was so thick with vegetation he still could not find the sign.
Treuer and a team of researchers from Princeton University studied the site over the course of the following three years.
The results, published in the journal "Restoration Ecology," highlight just how completely the discarded fruit parts assisted the area's turnaround.
The ecologists measured various qualities of the site against an area of former pastureland immediately across the access road used to dump the orange peels two decades prior. Compared to the adjacent plot, which was dominated by a single species of tree, the site of the orange peel deposit featured two dozen species of vegetation, most thriving.

In addition to greater biodiversity, richer soil, and a better-developed canopy, researchers discovered a tayra (a dog-sized weasel) and a giant fig tree three feet in diameter, on the plot.
"You could have had 20 people climbing in that tree at once and it would have supported the weight no problem," says Jon Choi, co-author of the paper, who conducted much of the soil analysis. "That thing was massive."
Recent evidence suggests that secondary tropical forests — those that grow after the original inhabitants are torn down — are essential to helping slow climate change.
In a 2016 study published in Nature, researchers found that such forests absorb and store atmospheric carbon at roughly 11 times the rate of old-growth forests.
Treuer believes better management of discarded produce — like orange peels — could be key to helping these forests regrow.
In many parts of the world, rates of deforestation are increasing dramatically, sapping local soil of much-needed nutrients and, with them, the ability of ecosystems to restore themselves.
Meanwhile, much of the world is awash in nutrient-rich food waste. In the United States, up to half of all produce in the United States is discarded. Most currently ends up in landfills.

"We don't want companies to go out there will-nilly just dumping their waste all over the place, but if it's scientifically driven and restorationists are involved in addition to companies, this is something I think has really high potential," Treuer says.
The next step, he believes, is to examine whether other ecosystems — dry forests, cloud forests, tropical savannas — react the same way to similar deposits.
Two years after his initial survey, Treuer returned to once again try to locate the sign marking the site.
Since his first scouting mission in 2013, Treuer had visited the plot more than 15 times. Choi had visited more than 50. Neither had spotted the original sign.
In 2015, when Treuer, with the help of the paper's senior author, David Wilcove, and Princeton Professor Rob Pringle, finally found it under a thicket of vines, the scope of the area's transformation became truly clear.

"It's a big honking sign," Choi emphasizes.
19 years of waiting with crossed fingers had buried it, thanks to two scientists, a flash of inspiration, and the rind of an unassuming fruit.

They were also there to shoot scenes for a documentary. And while they were hoping to capture some cool moments on camera, no one expected a huge chunk of a glacier to snap clean off and slide into the ocean right in front of their eyes.
Massive swells created by large chunks of glacier falling away.
It was the largest such event ever filmed.
For nearly an hour and 15 minutes, Balog and his crew stood by and watched as a piece of ice the size of lower Manhattan — but with ice-equivalent buildings that were two to three times taller than that — simply melted away.
A representation demonstrating the massive size of ice that broke off into the sea.
As far as anyone knows, this was an unprecedented geological catastrophe and they caught the entire thing on tape. It won't be the last time something like this happens either.
But once upon a time, Balog was openly skeptical about that "global warming" thing.
Balog had a reputation since the early 1980s as a conservationist and environmental photographer. And for nearly 20 years, he'd scoffed at the climate change heralds shouting, "The sky is falling! The sky is falling!"
"I didn't think that humans were capable of changing the basic physics and chemistry of this entire, huge planet. It didn't seem probable, it didn't seem possible," he explained in the 2012 documentary film "Chasing Ice."
There was too much margin of error in the computer simulations, too many other pressing problems to address about our beautiful planet. As far as he was concerned, these melodramatic doomsayers were distracting from the real issues.
That was then.
The glacier ice continues to erode away.
In fact, it wasn't until 2005 that Balog became a believer.
He was sent on a photo expedition of the Arctic by National Geographic, and that first northern trip was more than enough to see the damage for himself.
"It was about actual tangible physical evidence that was preserved in the ice cores of Greenland and Antarctica," he said in a 2012 interview with ThinkProgress. "That was really the smoking gun showing how far outside normal, natural variation the world has become. And that's when I started to really get the message that this was something consequential and serious and needed to be dealt with."
Some of that evidence may have been the fact that more Arctic landmass has melted away in the last 20 years than the previous 10,000 years.
