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.

Researchers dumped tons of coffee waste into a forest. This is what it looks like now.

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.

From political science to joining the fight against cancer: How one woman found her passion

An unexpected pivot to project management expanded Krystal Brady's idea of what it means to make a positive impact.

Krystal Brady/PMI

Krystal Brady utilizes her project management skills to help advance cancer research and advocacy.

True

Cancer impacts nearly everyone’s life in one way or another, and thankfully, we’re learning more about treatment and prevention every day. Individuals and organizations dedicated to fighting cancer and promising research from scientists are often front and center, but we don’t always see the people working behind the scenes to make the fight possible.

People like Krystal Brady.

While studying political science in college, Brady envisioned her future self in public office. She never dreamed she’d build a successful career in the world of oncology, helping cancer researchers, doctors and advocates continue battling cancer, but more efficiently.

Brady’s journey to oncology began with a seasonal job at a small publishing company, which helped pay for college and awakened her love for managing projects. Now, 15 years later, she’s serving as director of digital experience and strategy at the American Society of Clinical Oncology (ASCO), which she describes as “the perfect place to pair my love of project management and desire to make positive change in the world.”

As a project manager, Brady helps make big ideas for the improvement of diagnosing and treating cancer a reality. She is responsible for driving the critical projects that impact the lives of cancer researchers, doctors, and patients.

“I tell people that my job is part toolbox, part glue,” says Brady. “Being a project manager means being responsible for understanding the details of a project, knowing what tools or resources you need to execute the project, and facilitating the flow of that work to the best outcome possible. That means promoting communication, partnership, and ownership among the team for the project.”

At its heart, Brady’s project management work is about helping people. One of the big projects Brady is currently working on is ASCO’s digital transformation, which includes upgrading systems and applications to help streamline and personalize oncologists’ online experience so they can access the right resources more quickly. Whether you are managing humans or machines, there’s an extraordinary need for workers with the skillset to harness new technology and solve problems.

The digital transformation project also includes preparing for the use of emerging technologies such as generative AI to help them in their research and practices.

“Most importantly, it lays the groundwork for us to make a meaningful impact at the point of care, giving the oncologist and patient the absolute latest recommendations or guidelines for care for that specific patient or case, allowing the doctor to spend more time with their patients and less time on paperwork,” Brady says.

In today’s fast-changing, quickly advancing world, project management is perhaps more valuable than ever. After discovering her love for it, Brady earned her Project Management Professional (PMP)® certification through Project Management Institute (PMI)—the premier professional organization for project managers with chapters all over the world—which she says gave her an edge over other candidates when she applied for her job at ASCO.

“The knowledge I gained in preparing for the PMP exam serves me every day in my role,” Brady says. “What I did not expect and have truly come to value is the PMI network as well – finding like-minded individuals, opportunities for continuous learning, and the ability to volunteer and give back.”

PMI’s growing community – including more than 300 chapters globally – serves as a place for project managers and individuals who use project management skills to learn and grow through events, online resources, and certification programs.

While people often think of project management in the context of corporate careers, all industries and organizations need project managers, making it a great career for those who want to elevate our world through non-profits or other service-oriented fields.

“Project management makes a difference by focusing on efficiency and outcomes, making us all a little better at what we do,” says Brady. “In almost every industry, understanding how to do our work more effectively and efficiently means more value to our customers, and the world at large, at an increased pace.”

Project management is also a stable career path in high demand as shown by PMI research, which found that the global economy will need 25 million more project managers by 2030 and that the median salary for project managers in the US has grown to $120K.

If you’d like to learn more about careers in project management, PMI has resources to help you get started or prove your proficiency, including its entry-level Certified Associate in Project Management (CAPM) certification program. For those interested in pursuing a project management career to make a difference, it could be your first step.

Brielle Asero lost her job after 2 months.

TikTokker Brielle Asero, 21, a recent college graduate, went viral on TikTok in October for her emotional reaction to the first day at a 9-to-5 job. The video, which received 3.4 million views, captured the public’s attention because it was like a cultural Rorschach test.

Some who saw the video thought that Asero came off as entitled and exemplified the younger generation’s lack of work ethic. In contrast, others sympathized with the young woman who is just beginning to understand how hard it is to find work-life balance in modern-day America.

“I’m so upset,” she says in the video. "I get on the train at 7:30 a.m., and I don't get home until 6:15 p.m. [at the] earliest. I don't have time to do anything!" Asero said in a video.

Single dad receives letter from late wife and immediately gets a DNA test

"She wrote a letter for me before she died, but I couldn’t bring myself to read it until now."

A devastated man sitting by the ocean.

Ten months after a man’s wife passed away, he finally got the courage to read a letter she left him, which contained a devastating admission. The 4-year-old son they had together may not be his.

“My ‘darling’ wife passed away 10 months ago,” the man wrote on Reddit’s Off My Chest forum. “She wrote a letter for me before she died, but I couldn’t bring myself to read it until now. She told me how sorry she was that she didn’t have the guts to tell me this to my face when she was alive.”

In the letter, the wife revealed that there was a “good chance” that the son he thought was his wasn’t his biological child. A few weeks before their wedding day, the wife got drunk at her bachelorette party and had a one-night stand with another man. Soon after that night, she became pregnant but was unsure who the father was.

A viral photo of a calm dad and a screaming toddler holds an important parenting lesson

He exemplified patient parenting when his daughter started having a meltdown at the store.

Actor Justin Baldoni exemplified patient parenting when his daughter had a meltdown at the store.


Young kids don't always pick the best times to have emotional meltdowns.

Just ask any parent.

Grocery stores, malls, and restaurants (or any place with lots of people around) in particular seem to bring out the worst in our little ones, prompting explosive tantrums that can make even the most stoic parent turn red-faced with embarrassment.

But why be embarrassed? It's just kids being kids, after all.
