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.

An easy, actionable way to let President Trump know you're paying attention.
Put on your active citizen hat because the Department of Housing and Urban Development is seeking public comments on a proposed rule.
First, a little background.
In October 2016, HUD published a final rule, "Equal Access in Accordance with an Individual's Gender Identity in Community Planning and Development Programs."
It ensures people have equal access to HUD programs and shelters funded by HUD's Office of Community Planning and Development (CPD) regardless of their gender identity. It's actually an expansion of a 2012 rule that provided equal access to shelters and programs regardless of sexual orientation.
Sounds good so far, right?

The rule is great but only if people — especially those seeking emergency shelter or resources — know it exists.
As part of the rule, HUD is proposing owners and operators of CPD-funded buildings, housing units, and shelters post this rule in public places in their facilities (like bulletin boards and in the lobby) where people can see it. HUD would provide the content of the notice and the owners would just have to print it out and post it. HUD estimates the task will take six minutes.

Here's where all of us come in. HUD is seeking public comment on four things:
1. Whether the printout is necessary and useful.
2. Whether the six-minute estimate is accurate.
3. How to improve the quality, usefulness, or clarity of the document.
4. How to minimize the burden on people required to print out the document.
If you believe it's a good idea for HUD shelters and housing units to post this information, you can submit your comments electronically or by mail until Feb. 23, 2017.
Think giving feedback on something like this is trivial and unnecessary? Ask the genderqueer teen living on the streets who needs a place to crash and doesn't know if they're welcome at a local emergency shelter. Ask the transgender woman who was worried she'd be denied access to a home-buying program.
It may seem small, but to the individuals and families looking for resources and reassurance, it's significant.

More comments and feedback on the issues and proposed policies let the administration know we are paying attention.
This is only the first week of the new administration, and President Trump and his team have set several potentially devastating plans into motion. There's the unsanctioned gag order at the USDA, the devastating executive action prohibiting U.S. aid groups from funding NGOs that advise on or provide abortions, revival of the Keystone XL and Dakota Access oil pipelines, not the mention the promise to begin moving on his border wall.

You may not have the time or emotional energy to respond to every issue or proposal and that's OK.
With so much going on, it's easy to get discouraged and zone out. We have to persist. When we stop speaking up, reading, or getting involved, the administration's decisions go ignored and unchecked. There's just too much at stake to risk that.
Pick your issue: write a comment, make a call, attend a town hall, send a letter. Let Congress and Trump know you won't be silenced, bullied, or ignored. They work for us, and it's time they get a reminder.

Get ready. Your active citizen hat is going to be on for a while.
