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 forest experienced a radical, positive change
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.

Before you click 'send' on anything else, read this comic. It's important.
Everyone seems to be clicking "send" a bit too early nowadays.
We officially live in a world where internet trigger-happy world leaders can send massive populations into a devolved tail spin with erratic tweets, posts, and subsequent responses. These posts can have far-reaching consequences, and in the haste to respond in kind we've forgotten that we've normalized this kind of attitude.
Boulet is a French comic artist who has been writing about this for 15 years.
Originally he started writing an autobiographical series, but when he realized how accessible it was to his readers, he decided to make it fictional. "So it's mostly 'drawn stand up comedy,'" he explains. "I'm the main character, but in the same way comedians are there own character when they are on stage. The purpose is not really to talk about me but about situations of everyday's life everyone can relate to."
In his words, "The comic (below) was an anecdote about a Facebook mistake, I had basically two choices: Use it as a Facebook status to make my friends laugh or try to dramatize the whole process into an internal crisis to make it a story."

That "internal crisis" is something Boulet is very interested in.
Boulet enjoys using the accessible medium of cartoons as a way to explore complex issues. He loves learning about and studying consciousness and neuroscience. His fans enjoy this.
"There were fun discussions in the comments about how the brain works ... the very idea that we have a parallel process that can interfere, overlap or get in conflict is actually a thing. What I found most intriguing about this story was to literally feel my hand freeze BEFORE I could put an explanation on the WHY it froze."
He also had a great suggestion as to figuring out the motivations behind certain posts. "We should always go on social networks with EEGs on. We would learn a lot."
After what we've seen on social media over the last few years, it's hard to disagree.
