Ancient Hawaiians were agricultural masters.

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.

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.

"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?

Diver convinces a tiny octopus to trade a plastic cup for a shell in Pixar-worthy video

The cup wasn't a safe choice, but the little cephalopod was stubborn.

Plastic is a problem for ocean wildlife.

Sometimes taking care of our beautiful home planet looks like big, broad policies tackling issues like plastic pollution and habitat destruction. And sometimes it looks like taking the time to help one tiny creature stuck in an environmental bind.

In a YouTube video that's been viewed a whopping 20 million times, we see an example of the latter in action as some kind and compassionate divers attempt to convince an octopus to abandon the plastic cup it's using for protection and trade it for a sturdy shell. Pall Sigurdsson has shared dozens of underwater videos on YouTube, but watching this particular video from his dive off the coast of Lembeh, Indonesia, in 2018 almost feels like watching a Pixar short film.

"We spent a whole dive and most of our air saving this octopus from what was bound to be a cruel fate," Sigurdsson wrote in the description of the video.

"The coconut octopus, also known as veined octopus, is born with the instinct to protect itself by creating a mobile home out of coconut or clam shells. This particular individual however has been trapped by their instincts and have made a home out of a plastic cup they found underwater."

It's not just that the flimsy plastic cup didn't provide the octopus adequate protection. Sigurdsson explained that a predator like an eel or a flounder would probably end up swallowing the cup with the octopus in it, likely killing both of them. Plus, even if the octopus abandoned the cup on its own, plastic simply doesn't belong in the ocean.

"We tried for a long time to give it shells hoping that it would trade the shell," he wrote. "Coconut octopus are famous for being very picky about which shells they keep so we had to try with many different shells before it found one to be acceptable."

If you think an octopus in a cup making a decision about shells doesn't sound riveting, just watch:

The tentacles reaching out to test the weight of each shell, the divers searching for more options to offer it, the suspense of wondering whether the octopus really would abandon its pathetic plastic pollution protection...it's just too much.

Sigurdsson's other underwater videos are also fun to watch. He shared one of another veined octopus who seemed to have no interest in him but became intrigued with his diver friend, Gary. The way it reaches out to touch just the tip of his finger and then shyly retreats feels like such a clear communication with no words being said.

Octopuses are far more intelligent than anyone would have guessed before we started studying their behavior in earnest. They are known to solve puzzles, escape complicated mazes and traps, and take apart just about anything. It does make you wonder what these little guys were thinking when these divers were interacting with them. Was it curiosity? Judgment? An attempt at connection between species?

It's funny how one small interaction in one tiny portion of the vast ocean can say so much about us, for better and for worse. Human pollution is an enormous problem and saving one little octopus won't save the world, but it sure gives us hope and motivation to keep trying for the sake of the vast number of creatures that live in the ocean as well as our own.

Former Levi's CEO Charles Bergh settled the debate on how often you should wash your jeans

Levi's CEO Charles Bergh settles the jean washing debate

Social media has become a fertile breeding ground for conversations about hygiene. Whether it’s celebrities bragging about how little their family bathes or battles over how often people should wash their sheets or bras.

One of the debates that gets the most diverse responses is how often people wash their denim jeans.

Denim atelier Benjamin Talley Smith tells Today that jeans should be washed "as little as possible, if at all.” Laundry expert Patric Richardson adds they should be cleaned “after nine or 10 wearings, like to me, that is the ideal." At that point, they probably have stains and are "a little sweaty by that point, so you need to wash 'em," Richardson says.

Still, some people wash and dry them after every wear while others will hand wash and never hang dry. With all these significant differences of opinion, there must be a correct answer somewhere, right?

The former CEO of Levi Strauss, Charles Bergh, has stepped up to set the record straight on when and how to wash your jeans. He caused a stir in 2014 when he said he only washes his jeans once a year, but it was for environmental reasons more than hygiene.


He later clarified his thoughts in a blog post, “The Dirty Jean Manifesto” he posted to LinkedIn.

“I made this provocative statement because I believe strongly in what our brands stand for: quality, durability and lasting products made sustainably. I also said it because I believe we don’t need to wash jeans as often as most people think we do,” Bergh wrote.

"We learned that an average pair of jeans consumes roughly 3,500 liters of water — and that is after only two years of use, washing the jeans once a week," Bergh wrote. "Nearly half of the total water consumption, or 1,600 liters, is the consumer throwing the jeans in the washing machine. That’s equivalent to 6,700 glasses of drinking water!"

To add to the problem, denim jeans are often manufactured in places where water is scarce, such as India, Pakistan, Mexico, China and parts of California.

Bergh recently spoke with CNBC’s Christine Tan and clarified his thoughts on jean cleanliness.

“True denim heads, people that really love their denim, will tell you to never put your denim into a washing machine. So that’s what I do,” Bergh explained. “If I drop some curry on my jeans, I’m gonna clean it. But I’ll spot-clean it. And if they get really gross you know, if I’ve been out sweating or something and they get really gross, I’ll wash them in the shower.”

However, when Bergh washes his jeans in the shower, he does it while wearing them and washing them with soap. The image that the scene conjures is of a cowboy bathing in a cartoon, clothes on and all.

There are a lot of different opinions on how often one should wash and dry their jeans and many of them boil down to personal preference. But the debate on the topic has brought up one very big point we should all consider: when choosing how often we wash our jeans, a big part of the decision should be considering the amount of water we use.

A student accidentally created a rechargeable battery that she says could last 400 years

"This thing has been cycling 10,000 cycles and it’s still going." ⚡️⚡️

Steve Zylius/University of California, Irvine.

UCI doctoral candidate Mya Le Thai has developed a nanowire-based technology that allows lithium-ion batteries to be recharged hundreds of thousands of times.

There's an old saying that luck happens when preparation meets opportunity.

There's no better example of that than a 2016 discovery at the University of California, Irvine, by doctoral student Mya Le Thai. After playing around in the lab, she made a discovery that could lead to a rechargeable battery that could last up to 400 years. That means longer-lasting laptops and smartphones and fewer lithium ion batteries piling up in landfills.

A team of researchers at UCI had been experimenting with nanowires for potential use in batteries, but found that over time the thin, fragile wires would break down and crack after too many charging cycles. A charge cycle is when a battery goes from completely full to completely empty and back to full again.

But one day, on a whim, Thai coated a set of gold nanowires in manganese dioxide and a Plexiglas-like electrolyte gel.

"She started to cycle these gel capacitors, and that's when we got the surprise," said Reginald Penner, chair of the university's chemistry department. "She said, 'this thing has been cycling 10,000 cycles and it's still going.' She came back a few days later and said 'it's been cycling for 30,000 cycles.' That kept going on for a month."

This discovery is mind-blowing because the average laptop battery lasts 300 to 500 charge cycles. The nanobattery developed at UCI made it though 200,000 cycles in three months. That would extend the life of the average laptop battery by about 400 years. The rest of the device would have probably gone kaput decades before the battery, but the implications for a battery that that lasts hundreds of years are pretty startling.

“Mya was playing around, and she coated this whole thing with a very thin gel layer and started to cycle it,” said Penner added. “She discovered that just by using this gel, she could cycle it hundreds of thousands of times without losing any capacity.”

“That was crazy,” he added, “because these things typically die in dramatic fashion after 5,000 or 6,000 or 7,000 cycles at most. ”"The big picture is that there may be a very simple way to stabilize nanowires of the type that we studied," Penner said. "If this turns out to be generally true, it would be a great advance for the community." Not bad for just fooling around in the laboratory.

Since her discovery, Mya Le Thai has gone on to a successful career as the Principal Scientist with the Enevate Corporation,
