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.

How to criticize Caitlyn Jenner fairly — and oh, there's a lot to criticize.
A simple tip for tough discussions and disagreements.
Caitlyn Jenner has history of giving troubling sound bites.
In the wake of a shooting attack on Republican members of Congress, Jenner "joked" that "liberals can't even shoot straight." She once told BuzzFeed that, "the hardest part about being a woman is figuring out what to wear." During the 2016 election she said she wanted to be the "trans ambassador" for vehemently anti-LGBTQ politician Ted Cruz.
Take into account her public transition and her connection to the Kardashian family, there's no shortage of people ready and eager to call her out for comments like those.
I'm no fan of her, either. Trust me. Photo by Alberto E. Rodriguez/Getty Images.
Though we can't know for sure Jenner's intent, her status as a public figure and her habit of saying offensive, inappropriate, and ill-informed things makes life for trans people like me that much harder. She wants to speak for my demographic, and yet, when she opens her mouth, she often says things I vehemently disagree with.
It's embarrassing. It's exhausting.
Also exhausting, however, is the reaction I see play out every time Jenner says something problematic.
For every on-point criticism of whatever it is Jenner said, there are waves of people who respond with transphobic comments and "jokes" that misgender her and refer to her by her old name.
It certainly seems as though many people feel that Jenner saying or doing something awful gives them the green light to let out some general anti-trans feelings on the world — even if by accident.
While those sorts of comments may be directed at her, they send a really unfortunate message to all trans people, implying that being called the correct name and pronoun is a privilege to be "earned" and that can later be revoked in the case of bad behavior.
Those types of comments suggest that the person making them is merely humoring trans people when using our correct pronouns and names instead of taking us at our word when it comes to who we are.
The bottom line is this: Calling Caitlyn Jenner a "man" or using her old name doesn't really address what makes her so objectionable.
There's a name for this kind of bad argument.
It's called "ad hominem," and it's basically when someone comes to an argument to insult someone's character or body as opposed to their ideas. It's a pretty weak way to make a point, and honestly, it often affects more than the intended target.

So how can you criticize Caitlyn Jenner without being transphobic? Simple: Avoid ad hominem.
After Jenner's comments about the congressional shooting began circulating, here's an exchange I saw take place on Twitter:
One person posted a link to the recent story about her "liberals can't even shoot straight" comments. Out of nowhere, people replied to that tweet calling her a man, saying things about how her "real name" was "Bruce," and lots of stuff that had nothing to do with the stupid thing that she actually said.
A better way to respond would be to criticize her comments as being offensive or inappropriate in the wake of the tragedy she was talking about.
What if you just won't be satisfied unless you can crack a joke? LGBTQ activist Dan Savage pretty much nailed it with his response to her comments: "The liberal black lesbian married cop who took out the shooter got the job done."
Boom. Critical. Funny. Most importantly, not-transphobic.
There's nothing wrong with criticizing Caitlyn Jenner — whether the person doing the criticizing is trans or not.
Just because ad hominem attacks aren't OK doesn't mean Jenner gets some sort of "free pass" to say troubling things unchecked. It doesn't mean she shouldn't be held accountable for her words or that she shouldn't be criticized for her views or politics.
If people feel the need to criticize her for her political views, her charmed reality TV life, or her actions, they absolutely should do that. Believe me, there is plenty there to address.
There's just no need to bring transphobia into it.
Clarification 6/20/2017: A previous version of this post stated Jenner means well with her comments; it was updated to reflect that we don't know her intent.
