Can outsider beavers save this dried up river?

It's not easy being a river in the desert under the best of circumstances. The ecosystem exists in a very delicate balance, allowing water sources to thrive in the harsh conditions. These water sources in otherwise extremely dry areas are vital to the survival of unique wildlife, agriculture, and even tourism as they provide fresh drinking water for the people who live nearby.

But man-made problems like climate change, over-farming, and pollution have made a tough job even tougher in some areas. Rivers in Utah and Colorado that are part of the Colorado River Basin have been barely surviving the extremely harsh drought season. When the riverbeds get too dry, fish and other aquatic creatures die off and the wildfire risk increases dramatically.

About six years ago, one team of researchers had a fascinating idea to restore the health of some of Utah's most vulnerable rivers: Bring in the beavers.

In 2019, master's student Emma Doden and a team of researchers from Utah State University began a "translocation" project to bring displaced beavers to areas like Utah's Price River, in the hopes of bringing it back to life.

Why beavers? It just makes dam sense! (Sorry.)

Beaver dams restrict the flow of water in some areas of a river, creating ponds and wetlands. In drought-stricken areas, fish and other wildlife can take refuge in the ponds while the rest of the river runs dry, thus riding out the danger until it rains again.

When beavers are present in a watershed, the benefits are unbelievable: Better water quality, healthier fish populations, better nutrient availability, and fewer or less severe wildfires.

It's why beavers have earned the title of "keystone species," or any animal that has a disproportionate impact on the ecosystem around them.

Doden and her team took beavers who were captured or removed from their original homes due to being a "nuisance," interfering with infrastructure, or being in danger, and—after a short period of quarantine—were brought to the Price River.

Despite the research team's best efforts, not all the translocated beavers have survived or stayed put over the years. Some have trouble adapting to their new home and die off or are killed by predators, while others leave of their own accord.

But enough have stayed and built dams since 2019 that the team is starting to see the results of the effort. In fact, beaver projects just like this one have been going on all over the state in recent years.

The water levels in the river are now the healthiest they've been in years. The fish are thriving. Residents of Utah are overjoyed at the results of the experiment.

A column in The Salt Lake Tribune from 2025 (six years after the beaver translocation began) writes that the revitalization of the Price River "helped save our Utah town."

"A tributary of the Colorado River, the Price River runs through downtown Helper. On a warm day, you’re likely to find the river filled with tourists and locals kayaking, tubing and fishing along its shore. A decade ago, it was hard to imagine this scene—and the thriving recreation economy that comes with it—was possible."

Of course, it wasn't JUST the beavers. Other federal water cleanup investments helped remove debris, break down old and malfunctioning dams, and place tighter regulations on agriculture grazing in the area that depleted vital plant life.

But the experts know that the beavers, and their incredible engineering work, are the real MVPs.

In other drying, struggling rivers in the area, researchers are bringing in beavers and even creating manmade beaver dams. They're hoping that the critters will take over the job as the rivers get healthier.

Utah's San Rafael river, which is in bleak condition, is a prime candidate. In on area of the river, a natural flood inspired a host of beavers to return to the area and "riparian habitat along that stretch had increased by 230%, and it had the most diverse flow patterns of anywhere on the river," according to KUER.

It's hard to believe that beavers nearly went extinct during the heyday of the fur trapping industry, and continued to struggle as they were considered nuisances and pests. Now, they're getting the respect they deserve as engineer marvels, and their populations have rebounded due to better PR and conservation programs.

To that I say...it's about dam time!

Researchers dumped coffee waste into a forest and couldn't believe what it looked like 2 years later

We used to throw away 10 million tons of coffee pulp every year. These researchers may have found a better use for it.

Spreading coffee pulp over barren land lead to rapid forest growth.

Coffee, believe it or not, seems to be an ever-expanding market. The hot or cold, caf or decaf beverage gets more and more popular every year. That's in part due to the fact that people are drinking coffee younger and younger. Surely, you've seen the 10-year-olds ordering oatmilk shaken espressos out in the wild, and the high-schoolers starting each day with a hot cup of joe.

It's great news for Starbucks and Folgers, but maybe not such great news for the environment. Because 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, of which there are also increasingly many.

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. Remember, coffee pulp is made from the discarded bits of coffee cherries, not from used grounds. 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.

The coffee pulp did two things. First, it suppressed invasive grasses so that native growth could flourish. And second, it greatly elevated the nutrients in the soil, boosting phosphorous, carbon, and nitrogen levels – all key elements for rapid new growth.

"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. With a staggering 10 million hectares of land deforested globally every year (a hectare is an area of 10,000 square meters, just imagine 10 million of those) it's an urgent issue that could decide the fate of our entire planet.

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.

A trend appears when looking at the generational battles over the past decade. Millennials (1981 to 1996) are trying to create a more equitable world and repair the damage done by the generations before them. However, they have an uphill battle because baby boomers (1946 to 1965) still hold power in many aspects of American life.

Millennials grew up in an era impacted by 9-11, the Great Recession, the COVID-19 pandemic, and the cultural awakening that happened after the George Floyd murder. It’s wrong to paint an entire generation with the same brush. Still, millennials have favored progressive politics with a strong interest in helping to reverse the effects of climate change and fighting for equality. Culturally, millennials have preferred authenticity, whether it's the hipster movement or their love for craft beer, farmhouse decor, and all things chuegy.

Baby boomers need to pass the baton of leadership to Millennials. Do you agree? #boomers #millennials #millennialsoftiktok #fourthturning #generationtheory #genx #genz

What type of generation are the millennials?

Marilyn McKenna, 62, an intentional aging expert, says all of this makes sense given their generational trajectory. In a video with over 300,000 views, she says that, according to Neil Howe's 1997 book The Fourth Turning, millennials are considered a hero generation. In Turning, the authors postulate that every 80 to 100 years, there is an archetypal generational cycle in the order of prophets, nomads, heroes, and artists. Therefore, millennials are heroes whose job is to rescue America from a crisis that shakes it to its core.

“Hero generations come of age as community-based young adults during a Fourth Turning Crisis,” Alden Guzman writes. “If the outer world crisis is handled well, the hero generation is active participants in the building and championing of new values and institutions to face the crisis at hand.”

McKenna believes millennials have a significant job ahead of them, but there’s one big problem: it isn’t the task at hand; it’s baby boomers. "Whether in politics, media, corporate leadership, or the economy, boomers still occupy the majority of decision-making roles," McKenna said. "Many are reluctant to make space for new voices—not just millennials, but also Gen X and Gen Z. There's an unwillingness to acknowledge that the world has changed, and that old solutions aren't working."

Unfortunately, she believes that millennials are “screwed” because the boomers won't concede their power. She adds that boomers could play an essential role in changing society if they finally decided to step down. "It doesn't mean disappearing—it means mentoring, stepping back from dominance, and actively helping to prepare and elevate the next generation of leadership. But, too often, boomers have mistaken staying relevant for staying in control," McKenna continued.

McKenna says that the problems we face today stem from a crisis in agency because those who want to help are being stifled. "The historical patterns may be interesting and instructive, but they don't soften the day-to-day experience of living through a crisis. People are burned out, isolated, and losing faith in institutions,” she told Newsweek. “It's hard to know how to motivate people when they feel they have no real agency, and that's where I think we're stuck."

A sheet of ice the size of Manhattan tumbled into the sea.

Photographer James Balog and his crew were hanging out near a glacier when their camera captured something extraordinary. They were in Greenland, gathering footage from the time-lapse they'd positioned all around the Arctic Circle for the last several years.

They were also there to shoot scenes for a documentary. And while they were hoping to capture some cool moments on camera, no one expected a huge chunk of a glacier to snap clean off and slide into the ocean right in front of their eyes.

It was the glacier calving event ever filmed.

For nearly an hour and 15 minutes, Balog and his crew stood by and watched as a piece of ice the size of lower Manhattan — but with ice-equivalent buildings that were two to three times taller than that — simply melted away.

As far as anyone knows, this was an unprecedented geological catastrophe, and they caught the entire thing on tape. It won't be the last time something like this happens either.

But once upon a time, Balog was openly skeptical about that "global warming" thing.

Balog had a reputation since the early 1980s as a conservationist and environmental photographer. And for nearly 20 years, he'd scoffed at the climate change heralds shouting, "The sky is falling! The sky is falling!"

"I didn't think that humans were capable of changing the basic physics and chemistry of this entire, huge planet. It didn't seem probable, it didn't seem possible," he explained in the 2012 documentary film "Chasing Ice."

There was too much margin of error in the computer simulations, too many other pressing problems to address about our beautiful planet. As far as he was concerned, these melodramatic doomsayers were distracting from the real issues.

That was then.

In fact, it wasn't until 2005 that Balog became a believer.

He was sent on a photo expedition of the Arctic by National Geographic, and that first northern trip was more than enough to see the damage for himself.

"It was about actual tangible physical evidence that was preserved in the ice cores of Greenland and Antarctica," he said in a 2012 interview with ThinkProgress. "That was really the smoking gun showing how far outside normal, natural variation the world has become. And that's when I started to really get the message that this was something consequential and serious and needed to be dealt with."

Some of that evidence may have been the fact that more Arctic landmass has melted away in the last 20 years than the previous 10,000 years.

Balog has continued documenting changes in the Earth's seas, ice sheets, and other environmental indicators of climate change and spoke with CBS about his work in 2024. "When I started the extreme ice survey, climate change was still seen as a pretty abstract thing," Balog said. "It was something that was going to happen 20 or 30 or 50 years from now and my god when you could start to realize no, it's happening right now right in front of us. It put a real marker in time to say this is now, this is real."

Balog hopes that his photographic record will serve as a record of the present and a message to the future.

"I want to be able to say to those people of the distant future look not everybody in this time in you know 2024 was terribly conscious or cared about climate change," he said, "but I want to be able to say that this mind, these eyes, and this heart was paying attention."
