Researchers dumped tons of coffee waste into a forest. This is what it looks like now.
30 dump truck loads and two years later, the forest looks totally different.
One of the biggest problems with coffee production is that it generates an incredible amount of waste. Once coffee beans are separated from cherries, about 45% of the entire biomass is discarded.
So for every pound of roasted coffee we enjoy, an equivalent amount of coffee pulp is discarded into massive landfills across the globe. That means that approximately 10 million tons of coffee pulp is discarded into the environment every year.
When disposed of improperly, the waste can cause serious damage soil and water sources.
However, a new study published in the British Ecological Society journal Ecological Solutions and Evidence has found that coffee pulp isn't just a nuisance to be discarded. It can have an incredibly positive impact on regrowing deforested areas of the planet.

In 2018, researchers from ETH-Zurich and the University of Hawaii spread 30 dump trucks worth of coffee pulp over a roughly 100' x 130' area of degraded land in Costa Rica. The experiment took place on a former coffee farm that underwent rapid deforestation in the 1950s.
The coffee pulp was spread three-feet thick over the entire area.
Another plot of land near the coffee pulp dump was left alone to act as a control for the experiment.
"The results were dramatic." Dr. Rebecca Cole, lead author of the study, said. "The area treated with a thick layer of coffee pulp turned into a small forest in only two years while the control plot remained dominated by non-native pasture grasses."
In just two years, the area treated with coffee pulp had an 80% canopy cover, compared to just 20% of the control area. So, the coffee-pulp-treated area grew four times more rapidly. Like a jolt of caffeine, it reinvigorated biological activity in the area.
The canopy was also four times taller than that of the control.
The coffee-treated area also eliminated an invasive species of grass that took over the land and prevented forest succession. Its elimination allowed for other native species to take over and recolonize the area.
"This case study suggests that agricultural by-products can be used to speed up forest recovery on degraded tropical lands. In situations where processing these by-products incurs a cost to agricultural industries, using them for restoration to meet global reforestation objectives can represent a 'win-win' scenario," Dr. Cole said.
If the results are repeatable it's a win-win for coffee drinkers and the environment.
Researchers believe that coffee treatments can be a cost-effective way to reforest degraded land. They may also work to reverse the effects of climate change by supporting the growth of forests across the globe.
The 2016 Paris Agreement made reforestation an important part of the fight against climate change. The agreement incentivizes developing countries to reduce deforestation and forest degradation, promote forest conservation and sustainable management, and enhance forest carbon stocks in developing countries.
"We hope our study is a jumping off point for other researchers and industries to take a look at how they might make their production more efficient by creating links to the global restoration movement," Dr. Cole said.

Billie Eilish says Instagram comments were ruining her life. So she quit reading them. Smart.
Billie Eilish has gone from being a pop star to a superstar over the course of about a year. Her meteoric rise to fame has forced her to reevaluate how she deals with her fans online.
She used to be happy to read the comments on her Instagram feed, but the tone of the posts has become exceedingly negative. So she's decided to stop reading them altogether.
According to psychologists, that's a very good idea.
Eilish admitted she quit reading the comments during an interview with Louise Minchin from the BBC where she was joined by her brother, writer and producer, Finneas.
"Do you still read everything that's on Instagram?" Minchin asked.
"No, no. I stopped like two days ago," Billie responded. "Literally two days ago. I've stopped reading comments fully. Because it was ruining my life. It's weird. The cooler the things you get to do are, the more people hate you. It's crazy."
"How do you make it better?" the interviewer asked.
"The internet is a bunch of trolls. And the problem is that a lot of it is really funny," Billie said.
"Everyone is much braver behind a cell phone screen than they would be if they walked down the street," Finneas added.
"It's way worse than it's ever been right now," Billie admitted.
"It's insane that I even have been reading comments up until this point. I should've stopped long ago, it's just the problem is I've always wanted to stay in touch with the fans and keep talking to them, and people have ruined that for me, and for them. That sucks," she added.
However, the negativity Billie has faced online hasn't affected how she treats her fans in public.
"If I see fans anywhere, I just want to talk to them and be around them, because they're people. They're me! They're like other me's," the "Bad Guy" singer said. "They're like friends of mine, but the internet is ruining my life, so I turned it off."
Reading the comments on social media shouldn't be a huge problem for those of us who post things that are only seen by people we know. But for anyone in the public spotlight, being bombarded by negative comments day in and day out can be damaging.
That's because of a psychological trait called negativity bias.
According to Psycom's Margaret Jaworski, "We're more likely to register an insult or negative event than we are to take in a compliment or recall details of a happy event. The negativity bias can even cause you to dwell on something negative even if something positive is equally or more present."
Research suggests that it takes three positive comments to cancel out the effects of one negative remark.
Billie Eilish is smart to protect her own sanity by staying out of the comment section and not allowing it to affect her art or life. It's fine for the public to have access to her art but there's no reason she should be handing over her sanity as well.
