Once upon a time, in a land far, far away, the idea of sending a person to the moon was unfathomable. The moon is over 238,000 miles from Earth! How would anyone ever reach it safely, and more importantly, return to solid ground when the mission was complete?


But people are amazing, industrious creatures, and President John F. Kennedy was determined to make that giant leap. He referred to it as a ‘Moonshot;’ a play on words—a variation of “long shot,” describing a monumental effort and a lofty goal—uniting millions of people around an organized mission to put man on the moon. Moonshot catalyzed the development of technology as we know it.

Today, our challenge is more urgent. Humanity faces dire environmental problems requiring bold, groundbreaking solutions like, yesterday. In 2020, His Royal Highness Prince William, inspired by John F. Kennedy’s leadership in inspiring new innovation, launched The Earthshot Prize. He aims to find and grow the solutions that will repair our planet this decade; to regenerate the place we all call home. (Thanks, Prince William!)

The Earthshot Prize is the world’s most prestigious environmental award, involving a 10-month selection process, a panel of global experts, and a £1 million award for each winner to expand and launch their ideas.

“The Earth is at a tipping point and we face a stark choice: either we continue as we are and irreparably damage our planet, or we remember our unique power as human beings and our continual ability to lead, innovate and problem-solve. People can achieve great things. The next ten years present us with one of our greatest tests—a decade of action to repair the Earth,” said Prince William.

Fleather, a finalist in Build A Waste-free World

The prize is centered around 5 ‘Earthshots’ which are both simple and ambitious.

Protect and Restore Nature: By 2030, we choose to ensure that, for the first time in human history, the natural world is growing—not shrinking.

Clean Our Air: By 2030, we choose to ensure that everyone in the world breathes clean, healthy air—at World Health Organization standard or better.

Revive Our Oceans: By 2030, we choose to repair and preserve our oceans for future generations.

Build a Waste-free World: By 2030, we choose to build a world where nothing goes to waste, where the leftovers of one process become the raw materials of the next—just like they do in nature.

Fix Our Climate: By 2030, we choose to fix the world’s climate by cutting out carbon. We wish to build a carbon-neutral economy that lets every culture, community, and country thrive.

Out of the more than 1,000 nominations submitted, 3 finalists have been selected from each of the five categories, and the winners of the award (a total of 5, one from each category) is set to be announced at a ceremony in Boston, MA. The solutions and innovations represented by the 15 Finalists for 2022 will help to put the world firmly on a trajectory towards a stable climate.

One finalist in the Revive Our Oceans category is an invention titled “The Great Bubble Barrier,” created by a team of ocean enthusiasts based in The Netherlands. Francis Zoet, Anne Marieke Eveleens, and Philip Ehrhorn have developed an ingenious way to stop harmful plastic from reaching our oceans. Prevention is vital; every year, more than 8 million tons of plastic ends up in the world’s oceans, traveling in from rivers and canals. Once it enters the ocean, it is nearly impossible to capture and remove.

The Great Bubble Barrier has developed an effective solution designed to intercept plastic waste before it reaches the sea: the Bubble Barrier. The technology is simple: air is pumped through a perforated tube placed diagonally on the riverbed to create a “curtain” of bubbles, which directs plastic up to the surface and into a waste collection system, all without obstructing wildlife or boats. The concept has been used in the past by the oil industry to contain spills, and has now been developed to help local authorities remove debris from our rivers.

To date, the Bubble Barrier has been proven to catch on average 86% of plastic waste. Several Bubble Barriers have been installed in The Netherlands, including in the Westerdok, one of Amsterdam’s famous canals. Each month, Bubble Barrier Amsterdam stops an average of 8,000 pieces of plastic waste from leaving the canal and entering the North Sea. Two new Bubble Barriers will soon be implemented in Germany and Portugal. The team now hopes to scale the technology to reach polluted rivers worldwide.

Another compelling finalist is in the Fix Our Climate category, an Oman-based company known as 44.01. The founder and Carbon General, Talal Hasan, discovered a way to eliminate carbon by turning it into rock, removing it from the atmosphere safely, efficiently, and permanently.

“The answers to the problems our planet faces can often be found in the natural world,” said Hasan. “At 44.01, we found a natural process that removes carbon and we’ve accelerated it. We believe this process is replicable globally and can play a key role in helping our planet to heal. Thank you to The Earthshot Prize, for recognising our work.”

In addition to their eligibility for the £1 million prize, all finalists will receive tailored support and resources from the Earthshot Prize Global Alliance members, which is an unprecedented network of private sector businesses from around the world who are committed to healing our planet. The list is lengthy and varied, spanning from Greenpeace to Walmart.

“I am so excited to celebrate these 15 Finalists and see the 5 Winners of The Earthshot Prize announced in Boston – the hometown of President John F. Kennedy, who shared The Earthshot Prize’s belief that seemingly impossible goals are within reach if we only harness the limitless power of innovation, human ingenuity, and urgent optimism,” said Prince William.

The Earthshot Prize awards ceremony will take place on Friday, December 2 at the MGM Music Hall in Boston. It will air around the world on BBC in the UK, PBS in the United States and Multichoice across Africa. The show will also be available globally on YouTube. It will premiere on Sunday, December 4.

    One hundred twenty-five years ago, the Pasterze Glacier in Austria’s Eastern Alps was postcard perfect: Snowy peaks. Windswept valleys. Ruddy-cheeked mountain children in lederhosen playing “Edelweiss” on the flugelhorn.

    But a lot has changed since 1900. Much of it has changed for the better. We’ve eradicated smallpox, Hitler is dead, and the song “Billie Jean” exists now. On the downside, the Earth has gotten hotter. A lot hotter. From June 2023 to May 2024, each subsequent month was the hottest ever recorded in the planet’s history. July 2023 was the planet’s hottest month—ever. And as of this writing, Yale Climate Connections declared June 2025 “the planet’s third-warmest in history.”

    Unsurprisingly, man-made climate change has wreaked havoc on the planet’s glaciers—including the Pasterze, which is Austria’s largest. Just how much havoc are we talking about? Well, this is how the Pasterze Glacier looked in a 1900 postcard:

    And this is how it looked in March 2025:

    Pasterze Glacier, Pasterze, Austria, climate change, alps, Eastern Alps
    What's left of the Pasterze Glacier European Union, Copernicus Sentinel-2 imagery

    First measured in 1851, the glacier lost half of its mass between 1856 (when it first began receding) and the early 2000s. A marker placed in 1985 shows where the edge of the glacier reached just 40 years ago. You can still see the ice sheet, but just barely, way off in the distance. In between is…a big, muddy lake. The view from the glacial foot marker from 1995—just 10 years later—isn’t much more encouraging. Even in just one year, 2015, the glacier lost an astounding amount of mass—177 feet, by some estimates.

    Overall, it is estimated that the glacier has retracted by 980 feet since the park first opened in 1963.

    Ice continues to melt daily, and while the dripping makes for a good photo, it’s unfortunate news for planet Earth. Glacial melting is one of the three primary causes of sea-level rise. Pasterze is still technically the largest glacier in Austria and the Eastern Alps at approximately 6.2 miles. And even in its reduced form, Pasterze remains a significant tourist destination.

    According CREA Mont-Blanc, a research center for Alpine Ecosystems, the average temperature in the Alps has increased two degrees Celsius in the last 100 years—double the global average. It’s not unreasonable to assume that that’s why this mountain hut has been abandoned by the flugelhorn-playing children who once probably lived in it.

    Is there anything we can do to stop the Pasterze Glacier from disappearing?

    There are efforts underway to save Pasterze and other significant glaciers. However, Gerhard Lieb, the co-leader of the Austrian Alpine Club described the glacier’s retreat as “unstoppable” with predictions that it and Austria’s other major glaciers will be gone in as little as 45 years. It would take decades of meaningful counter climate change initiatives, with even the existing ones being too slow for meaningful action, “and the time is up,” Lieb said. “That means nothing can be done anymore.”

    What the world looks like if all the land ice melts

    These maps show the shocking answer to a terrifying “what if” scenario.

    Land ice: We got a lot of it. Considering the two largest ice sheets on earth — the one on Antarctica and the one on Greenland — extend more than 6 million square miles combined … yeah, we’re talkin’ a lot of ice. But what if it was all just … gone? Not like gone gone, but melted?

    If all of earth’s land ice melted, it would be nothing short of disastrous. And that’s putting it lightly. This video by Business Insider Science (seen below) depicts exactly what our coastlines would look like if all the land ice melted. And spoiler alert: It isn’t great. Lots of European cities like, Brussels and Venice, would be basically underwater.

    I bring up the topic not just for funsies, of course, but because the maps are real possibilities.

    How? Climate change.

    As we continue to burn fossil fuels for energy and emit carbon into our atmosphere, the planet gets warmer and warmer. And that, ladies and gentlemen, means melted ice.

    A 2015 study published by researchers in the U.S., U.K., and Germany found that if we don’t change our ways, there’s definitely enough fossil fuel resources available for us to completely melt the Antarctic ice sheet.

    Basically, the self-inflicted disaster you see above is certainly within the realm of possibility.

    Millions of people in Asia, in cities like Mumbai, Beijing, and Tokyo, would be uprooted and have to move inland.

    And in the U.S., we’d watch places like Houston, San Francisco, and New York City — not to mention the entire state of Florida — slowly disappear into the sea.

    Business Insider based these visuals off National Geographic’s estimation that sea levels will rise 216 feet (!) if all of earth’s land ice melted into our oceans.

    There’s even a tool where you can take a detailed look at how your community could be affected by rising seas, for better or worse.

    Although … looking at these maps, it’s hard to imagine “for better” is a likely outcome for many of us.

    Much of America’s most populated regions would be severely affected by rising sea levels, as you’ll notice exploring the map, created by Alex Tingle using data provided by NASA.

    Take, for instance, the West Coast. (Goodbye, San Fran!)

    And the Gulf Coast. (RIP, Bourbon Street!)

    “This would not happen overnight, but the mind-boggling point is that our actions today are changing the face of planet Earth as we know it and will continue to do so for tens of thousands of years to come,” said lead author of the study Ricarda Winkelmann, of the Potsdam Institute for Climate Impact Research.

    If we want to stop this from happening,” she says, “we need to keep coal, gas, and oil in the ground.”

    The good news? Most of our coastlines are still intact! And they can stay that way, too — if we act now.

    While world leaders have made pledges and set goals since this article first appeared, the crisis remains. You can help get the point across to them, too.

  • Ancient Hawaiian land system could transform sustainability’s future—and it’s going viral
    Ancient Hawaiians were agricultural masters. Photo credit: Canva

    Switch to electric, use less water, recycle everything: in a time when fighting climate change seems insurmountable, an incredible solution is re-emerging from the ancient past—and it’s making major waves on TikTok. The ahupuaʻa system, Hawai’i’s approach to land management before the once-sovereign nation was colonized, is shocking the world as people discover its incredible potential to revolutionize sustainability—and potentially solve our modern climate crisis.

    You cannot convince me we are more technologically advanced when ancient societies used nature as their technology and balanced themselves for thousands of years. VC: Hyperspective on IG. #landback #foodsoverignty #indigenous #wisdom #tiktok #fyp

    ♬ Lights Are On – Instrumental – Edith Whiskers

    Meet Benjamin Kaimipono (@ben_jamin_witu), a Native Hawaiian (Kanaka ‘Ōiwi) TikTok creator whose videos—some original, some reposts—about Native Hawaiian life, practices, and history are creating a vitally important tapestry of a culture erased. One of the videos, a repost from @hyperspective on Instagram, (a boutique creative agency in Honolulu) depicts a simulated version of the Hawaiian ahupua’a system with the caption: “You cannot convince me we are more technologically advanced when ancient societies used nature as their technology and balanced themselves for thousands of years.”

    The responses are filled with pride, respect, and wonder. One commenter wrote, “This is why land back is crucial today with global warming at an all-time high! Indigenous peoples are in tune with the land and know better than anyone else how to take care of it ✊ .” Others appreciated Kaimipono’s sharing of Native Hawaiian knowledge, with one person writing: “This… is the proper use of the ‘āina. live and learn and always Aloha ‘Āina. Proud to be Hawaiian. Ha’aheo au. ” (According to Lāna’i Culture & Heritage Center, “’āina” is generally translated as “land” but directly means “that which feeds”; “Ha’aheo au” means “I am proud.”)

    Another wrote:

    “Hawaiians understood what it meant to live righteously off the land, and we’re centuries ahead of their time with resource management. There’s connection to the land is a key value. That’s why native cultures always knew how to be sustainable with the resources they had, and didn’t overuse or destroy it.”

    Why this ancient system works

    The ahupua’a system, which thrived in Hawai’i for nearly a millennium between 1000 CE to 1848, wasn’t just smart—it was mathematic, geologic, and climatic genius. Picture this: 725 perfectly organized sections across eight islands. Each land parcel averages 5,678 and works in perfect harmony with nature. It was symbiosis at its finest: each ahupua’a operated like a self-contained utopia, combining forests, crops, and fishing zones, demonstrating a master class in resource management. This way, Hawaiians were able harness the power of the ecosystems around them while both supporting the 800,000 people living on the islands (and growing) and maintaining the land’s integrity.

    In their seminal paper, “The Ahupua’a as a Traditional Hawaiian Resource Management Model for a Sustainable Coastal Environment,” researchers David W. Blane and Christopher Chung describe the ahupua’a as “a practical and rational approach to resources management that conforms with the existing geography and its resources rather than altering them for human convenience,” adding:

    “…as you may already have surmised, the ahupua‘a means much more. The ahupua‘a embodies a unique relationship between the Hawaiian people and the land as well as the practical and rational approaches applied to insure the sustainability of the natural environment from overexploitation, pollution, and extinction.”

    Land management magic

    This could get very scientific very fast, but here’s the simple version: ahupua’a were wedge-shaped land units that spanned from the mountains (mauka) down through the cultivated lowlands (mala) to the sea (makai). This way, each unit, each slice, had everything they needed to survive: forests to harvest wood from and collect bird feathers; irrigated agricultural terraces (lo’i) where they mostly grew taro, and dryland farms used to cultivate sweet potato (’uala), coconuts (niu), breadfruit (’ulu), and bananas (mai’a), just to name a few. Each ahupua’a also contained a coastal and marine area, where Hawaiians could fish and produce salt.

    The leadership structure was also pure brilliance: each ahupua’a had its own chief (ali’i), overseer (konohiki), and priests (kahuna) who worked together, overseeing the administration of their land and ensuring that resources were used efficiently and sustainably. But perfection on this scale takes more than just good delegation; the ahupua’a leadership also incorporated important Native Hawaiian values like respect (aloha), cooperation (laulima), and stewardship (mālama) to ensure that everything remained balanced (pono). According to the North Shore Sustainable Communities Plan, here’s what made it all work:

    • When resources ran low, they immediately stopped harvesting to preserve resources.
    • They closed certain fishing areas seasonally so fish populations could bounce back.
    • Inter-ahupua’a trade was commonplace, so residents felt connected, and the system kept strong.

    fruit, land, sustainability, Hawai'i, ahupua'a
    Ahupua'a was a brilliant, sustainable practice. Thorsten

    “The Hawaiians believed that the land, the sea, the clouds and all of nature had a certain interconnectedness, which is why they used all of the resources around them to reach the desired balance in life.” – Nation of Hawaii

    As we watch our food systems fall apart, coastlines disappear, and farmlands struggle, remember: it doesn’t have to be this way. Modern urban planners could take a page out of the ancient Native Hawaiian’s book, as they construct our future cities, structures, and systems. No one is asking for a 180 total rehaul or a return to 1848. But there are small things we can do. In Hawai’i, they’ve already brought a few of these principles back to life. They’re restoring traditional fishponds, reconnecting forests with their corresponding coastal areas, and empowering local communities to steward their own resources. This is a real, sustainable way forward. Or, as the BBC said: “The ahupuaʻa system of land development, in practice for more than 1,000 years, has the potential to show the world a new path to sustainability.” Are you ready to be a part of that change?

  • Doctor warns that having this in your bathroom is a huge red flag for your health

    It’s easy to tell if mold is growing in your bathroom: you notice the black stuff growing on the caulk that lines your bathtub or near the bottom of the hot and cold water handles on your sink. But have you ever seen a ring of pink slime accumulating around your sink drain or on the bottom of your shower curtain? Most people think it’s mold, but it’s actually something worse.

    U.K.-based surgeon Dr. Karan Rajan explained the pink slime phenomenon in a TikTok video that’s received over 640,000 views. “You’ve seen this pink slime lurking in your bathroom, it’s not mold, it’s bacteria,” Dr. Rajan says. “Specifically one called Serratia marcescens. And it vomits hot pink all over your bathroom.”

    Yes, that’s not soap that has turned a bubble-gum color on the bottom of your shower curtain or Pepto Bismol that didn’t go down the drain. It’s bacteria vomit.

    The interesting thing about this bacteria is that the products you use to clean your body in the shower or wash your hands in the sink are what it loves to eat. Pink slime feeds on fat and mineral deposits from soap scum and shampoo.

    If you’ve found some pink slime in your home before, you know it’s much grosser than you originally thought. But is it dangerous? “[To] the average person, it’s pretty harmless, even if you come into contact with it, but you still wanna avoid getting in your eyes or open wounds,” Dr. Raja warns. “However, it can cause gut, urine, or chest infections in those who are immunocompromised.”

    “OMG this reappears in our tub every few weeks. I was wondering what it was!?” someone wrote in the comments on the TikTok post. “I always wondered. The pink slime and my bleach bottle are in a constant battle,” another added.

    The bigger problem of pink slime is that it may be a symptom of a more significant issue. “If your home has enough damp for pink slime to consistently develop, you could actually be growing other things as well, like actual household molds, which could be causing respiratory issues or allergies,” Dr. Rajan says.

    How to clean pink slime (Serratia marcescens)

    Here is how to clean and sanitize your bathroom of pink slime, thanks to This Old House.

    1. Wear safety glasses, a mask, and gloves
    2. Combine 2 tablespoons of dish soap with one quarter cup of baking soda
    3. Apply the mixture to the bacteria and scrub thoroughly with a nylon brush
    4. Rinse away the loosened bacteria
    5. Spray the affected area with 1:1 warm water and bleach solution
    6. Let sit for ten minutes, then scrub again
    7. Dry with a microfiber towel

    How to prevent pink slime from growing in your bathroom

    How do you keep pink slime from growing in your home in the first place? The key is to keep your bathroom dry. “The first rule of Pink Slime Club is to keep the bacteria forming in the first place. By curbing its growth, you’ll be preventing other dangerous molds from forming,” Dr. Rajan says. “Keep your shower dry and well-ventilated, put on an exhaust fan or open a window after showering to keep humidity levels low, and regularly clean and disinfect your bathroom. It’s filthier than you think.”
