A juice company dumped orange peels in a national park. Here's what it looks like now.

In 1997, ecologists Daniel Janzen and Winnie Hallwachs approached an orange juice company in Costa Rica with an off-the-wall idea.

In exchange for donating a portion of unspoiled, forested land to the Área de Conservación Guanacaste — a nature preserve in the country's northwest — the park would allow the company to dump its discarded orange peels and pulp, free of charge, in a heavily grazed, largely deforested area nearby.

One year later, one thousand trucks poured into the national park, offloading over 12,000 metric tons of sticky, mealy, orange compost onto the worn-out plot.

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.

Even as millions of Americans celebrated the inauguration of President Joe Biden this week, the nation also mourned the fact that, for the first time in modern history, the United States did not have a peaceful transition of power.

With the violent attack on the U.S. Capitol on January 6, when pro-Trump insurrectionists attempted to stop the constitutional process of counting electoral votes and where terrorists threatened to kill lawmakers and the vice president for not keeping Trump in power, our long and proud tradition was broken. And although presidential power was ultimately transferred without incident on January 20, the presence of 20,000 National Guard troops around the Capitol reminded us of the threat that still lingers.

First Lady Jill Biden showed up today with cookies in hand for a group of National Guard troops at the Capitol to thank them for keeping her family safe. The homemade chocolate chip cookies were a small token of appreciation, but one that came from the heart of a mother whose son had served as well.

If the past year has taught us nothing else, it's that sending love out into the world through selfless acts of kindness can have a positive ripple effect on people and communities. People all over the United States seemed to have gotten the message — 71% of those surveyed by the World Giving Index helped a stranger in need in 2020. A nonprofit survey found 90% helped others by running errands, calling, texting and sending care packages. Many people needed a boost last year in one way or another and obliging good neighbors heeded the call over and over again — and continue to make a positive impact through their actions in this new year.

Upworthy and P&G Good Everyday wanted to help keep kindness going strong, so they partnered up to create the Lead with Love Fund. The fund awards do-gooders in communities around the country with grants to help them continue on with their unique missions. Hundreds of nominations came pouring in and five winners were selected based on three criteria: the impact of action, uniqueness, and "Upworthy-ness" of their story.

Here's a look at the five winners:

Edith Ornelas, co-creator of Mariposas Collective in Memphis, Tenn.

Edith Ornelas has a deep-rooted connection to the asylum-seeking immigrant families she brings food and supplies to families in Memphis, Tenn. She was born in Jalisco, Mexico, and immigrated to the United States when she was 7 years old with her parents and sister. Edith grew up in Chicago, then moved to Memphis in 2016, where she quickly realized how few community programs existed for immigrants. Two years later, she helped create Mariposas Collective, which initially aimed to help families who had just been released from detention centers and were seeking asylum. The collective started out small but has since grown to approximately 400 volunteers.
