From the article:

The two students presented their groundbreaking project at the 2024 International Science and Engineering Fair (ISEF); a device that operates by using ultrasound waves to push microplastic particles to one side of a water flow, allowing clean water to pass through while trapping the contaminants. In their tests, the system successfully captured up to 94 per cent of microplastic particles, showing promise for real-world applications.   "If we could refine this, maybe use more professional equipment, maybe go to a lab instead of testing from our home, we could really improve our device and get it ready for large-scale manufacturing," Justin told Business Insider. The duo envisioned their device being used in water treatment plants, directly modifying the quality of water for daily use. This application could significantly reduce the amount of microplastics that end up in water sources, protecting ecosystems and human health.

1. Solar farms managed for nature boost bird abundance and diversity, new study finds

“There were more than twice as many farmland birds in the well-managed solar farms compared with the intensively farmed land, and nearly 16 times as many woodland birds. […] Overall, diversity was 2.5 times higher, while woodland birds were nine times more diverse.”

2. Washington judge blocks Trump’s gender-affirming care ban, says it's unconstitutional in multiple ways

“This marks the second time in a week that a judge has stood in the way of Trump’s attacks on trans kids. [… The ruling grants] a temporary restraining order that halts enforcement of provisions in Trump’s directive that would cut off federal funding to medical institutions that provide gender-affirming care to minors.”

3. Fog harvesting could provide water for arid cities

“17,000 sq m of mesh could produce enough water to meet the weekly water demand of [… the] urban slums. 110 sq m could meet the annual demand for the irrigation of the city's green spaces. Fog water could be used for soil-free (hydroponic) agriculture, with yields of 33 to 44lb (15 to 20kg) of green vegetables in a month.”

4. Audubon Applauds Bipartisan Federal Effort to Protect Delaware River Basin with Critical Reauthorization Bill

“The bill would […] ensure long-term conservation and restoration efforts, expand the official definition of the basin to include Maryland, and prioritize projects that serve small, rural, and disadvantaged communities. […] The watershed provides important year-round habitats and critical migratory stopovers for approximately 400 bird species[….]”

5. mRNA vaccines show promise in pancreatic cancer in early trial

“Half of the people in the study — eight of the participants — responded to the vaccine, producing T cells that targeted their tumors. […] Just two of the patients who had a response to the vaccine had their cancer return during the three-year follow- up, compared to seven of the eight who did not respond to the vaccine treatments.”

6. Minn. Lt. Gov. Flanagan Makes It Official; She's running for U.S. Senate

“[Flanagan has] “championed kitchen-table issues like raising the minimum wage, paid family and medical leave, and free school meals.” If elected, Flanagan, a tribal citizen of the White Earth Nation, would become the first Native American female U.S. senator in history.”

7. Federal Funding Restored for Low-Income Alabama Utility Assistance After Outcry

“A program meant to help low-income Alabamians pay their utility bills has resumed two weeks after it was canceled due to an executive order from President Donald Trump. […] “We can confirm the funds are reaching those affected by the previous pause[….]””

8. Modeling study suggests Amazon rainforest is more resilient than assumed

“[Previous] studies were either conducted with global climate models that used a simplified representation of convection [or were on a regional scale….] According to the computations, mean annual precipitation in the Amazon does not change significantly even after complete deforestation.“

9. States are moving forward with Buy Clean policies despite Trump reversal

““Buy Clean is a great example of how states and other nonfederal actors can continue to press forward on climate action, regardless of what the federal government does,” said Casey Katims, executive director of the U.S. Climate Alliance, a bipartisan coalition of two dozen governors.”

10. The rewilded golf courses teeming with life

“A wildflower meadow, ponds, scrub habitat, coastline and even an area of peat bog can be found on this little 60-acre (24-hectare) plot, which boasts roe deer, otters, lizards, eels and a huge array of insects and birds.”

Legit though, we should start turning ecosystem restoration and work to make our world more tolerant to the effects of climate change into annual holidays and festivals

Like how just about every culture used to have festivals to celebrate the beginning of the harvest or its end, or the beginning of planting, or how whole communities used to host barn raisings and quilting bees - everyone coming together at once to turn the work of months or years into the work of a few days

Humble suggestions for festival types:

Goat festival

Besides controlled burns (which you can't do if there's too much dead brush), the fastest, most effective, and most cost-efficient way to clear brush before fire season - esp really heavy dead brush - is to just. Put a bunch of goats on your land for a few days!

Remember that Shark Tank competitor who wanted to start a goat rental company, and everyone was like wtf? There was even a whole John Oliver bit making fun of the idea? Well THAT JUST PROVES THEY'RE FROM NICE WET PLACES, because goat rental companies are totally a thing, and they're great.

So like. Why don't we have a weekend where everyone with goats just takes those goats to the nearest land that needs a ton of clearing? Public officials could put up maps of where on public lands grazing is needed, and where it definitely shouldn't happen. Farmers and people/groups with a lot of acres that need clearing can post Goat Requests.

Little kids can make goat-themed crafts and give the goats lots of pets or treats at the end of the day for doing such a good job. Volunteers can help wrangle things so goats don't get where they're not supposed to (and everyone fences off land nowadays anyway, mostly). And the goats, of course, would be in fucking banquet paradise.

Planting Festival and Harvest Festival

Why mess with success??? Bring these back where they've disappeared!!! Time to swarm the community gardens and help everyone near you with a farm make sure that all of their seeds are sown and none of the food goes to waste in the fields, decaying and unpicked.

And then set up distribution parts of the festival so all the extra food gets where it needs to be! Boxes of free lemons in front of your house because you have 80 goddamned lemons are great, but you know what else would be great? An organized effort to take that shit to food pantries (which SUPER rarely get fresh produce, because they can't hold anything perishable for long at all) and community/farmer's markets

Rain Capture Festival

The "water year" - how we track annual rainfall and precipitation - is offset from the regular calendar year because, like, that's just when water cycles through the ecosystems (e.g. meltwater). At least in the US, the water year is October 1st through September 30th of the next year, because October 1st is around when all the snowmelt from last year is gone, and a new cycle is starting as rain begins to fall again in earnest.

So why don't we all have a big barn raising equivalent every September to build rain capture infrastructure?

Team up with some neighbors to turn one of those little grass strips on the sidewalk into a rain-garden with fall-planting plants. Go down to your local church and help them install some gutters and rain barrels. Help deculvert rivers so they run through the dirt again, and make sure all the storm drains in your neighborhood are nice and clear.

Even better, all of this - ESPECIALLY the rain gardens - will also help a ton with flood control!

I'm so serious about how cool this could be, yall.

And people who can't or don't want to do physical stuff for any of these festivals could volunteer to watch children or cook food for the festival or whatever else might need to be done!

Parties afterward to celebrate all the good work done! Community building and direct local improvements to help protect ourselves from climate change!

The possibilities are literally endless, so not to sound like an influencer or some shit, but please DO comment or reply or put it in the notes if you have thoughts, esp on other things we could hold festivals like this for.

Canning festivals. "Dig your elderly neighbors out of the snow" festivals. Endangered species nesting count festival. Plant fruit trees on public land and parks festival. All of the things that I don't know anywhere near enough to think of. Especially in more niche or extreme ecosystems, there are so many possibilities that could do a lot of good

hey do you live in utah please take this survey!!! aug 2023

if you do please take this government survey about water usage, housing development, and public transit development in the near future!

particular things to watch for:

should we require low-water-use landscaping on new development

should we require existing wasteful landscaping for businesses and home developments be replaced with low-water-use landscaping

encouraging field fallowing -- currently utah's policy means a farmer can lose water rights on a field if they don't water it every year even if theyre not growing somwthing. fallowing would allow for people to let fields rest by not planting or watering on off years, massively reducing water waste

encouraging public transport in the form of fareless buses and trains, increasing pedestrian areas and bike lanes

reducing highway development thank god

developing dead malls and huge parking lots into more housing and pedestrian areas

please take it it's not terribly long and is pretty well formatted so it's easily digestible! utahs water policy and development has been ATROCIOUS lately this could really shape the future into something better. if u dont live in utah sharing would be appreciated <3

Grey Water Recycling Systems: Your Guide to Sustainable Water Management at Home

As environmental awareness grows, homeowners and businesses alike are seeking ways to conserve resources and reduce their ecological footprints. One highly effective solution is implementing a grey water recycling system. Grey water systems allow you to reuse water from sinks, showers, and washing machines for non-potable purposes, reducing both water consumption and utility costs. In this…

From the article:

“We really kind of refer to this as our third aqueduct,” says John Bednarski, an interim assistant general manager at the Metropolitan Water District of Southern California — a powerful agency, as the largest wholesale provider of water in the nation and owner of the Colorado River Aqueduct. The “third aqueduct” Bednarski is referring to is not another man-made appendage stretching to the Colorado River Basin or into Northern California but rather a project that’s designed to stay local — and sustainable: Pure Water Southern California would recycle wastewater, treat it and produce 150 million gallons of water each day, accounting for about 10 percent of the agency’s local water demands, according to Bednarski. “So it’s going to be a major contributor,” he says. [...] The L.A. Department of Water and Power is pursuing a similar recycling project. And in 2022, 26 cities and wholesale water providers that pull from the Colorado River wrote a memorandum of understanding committing to focusing on water recycling and reuse. The signatories, including Metropolitan, often point to Las Vegas as a model for recycling wastewater to reduce its total Colorado River use and increase the amount of water available for use. Nevada has long faced scarcity; of all the states, it receives the smallest share of the river: just 1.8 percent of all the water rights. By treating and reusing nearly all of its indoor water, the Las Vegas water purveyor effectively uses the same water over and over, expanding its supply. Now Las Vegas officials, along with Arizona water managers, are looking to the Pure Water project to further shore up supplies on the Colorado River. Their thinking: If Metropolitan can reduce its Colorado River use, its unused water could flow to Nevada and Arizona, providing a needed boost in an era when there is little to spare.  In that way, water recycling projects in one area can have consequences across watersheds."

1. Climate Initiatives Fare Well Across the Country Despite National Political Climate

“[California voters approved] a $10 billion bond measure to boost climate resilience across [the] state[…. Hawai’i] voters cast their ballots in favor of establishing the [climate] resiliency fund, with money for the project coming from existing property tax revenue.“

2. ‘You have to disguise your human form’: how sea eagles are being returned to Severn estuary after 150 years

“[… To avoid imprinting,] the handlers will wear long robes and feed the young eagles chopped rabbit and other meat with bird hand-puppets. […] Williams hopes that restoring eagles to the top of the food chain in the estuary will create a more balanced, thriving ecosystem.”

3. 10 states voted on pro-abortion referendums. 7 of them passed

“New York voters overwhelmingly approved the Equal Rights Amendment, adding [… among other characteristics] gender expression, pregnancy, and pregnancy outcomes to anti-discrimination laws. […] In deep-red Missouri and Montana, voters also enshrined abortions protections in their state constitutions.”

4. Giant rats could soon fight illegal wildlife trade by sniffing out elephant tusk and rhino horn

“”Our study shows that we can train African giant pouched rats to detect illegally trafficked wildlife, even when it has been concealed among other substances[.…] They can easily access tight spaces like cargo in packed shipping containers or be lifted up high to screen the ventilation systems of sealed containers,” Szott explained.”

5. Sarah McBride wins Delaware U.S. House seat, becoming the first out trans member of Congress

“McBride spearheaded Delaware’s legislation to ban the “gay and trans panic” defense as a state senator [… and] helped to pass paid family and medical leave, gun safety measures, and protections for reproductive rights.”

6. Critically endangered Sumatran elephant calf born in Indonesia

“Indonesian officials hailed the births and said they showed conservation efforts were essential to prevent the protected species from extinction. […] Sumatran elephants are on the brink of extinction with only about 2,400-2,800 left in the world, according to the World Wide Fund for Nature.”

7. Sin City is Going Green

“[Hotels there] have conserved 16 billion gallons of water since 2007, thanks to […] replacing grass with desert-friendly landscaping, installing water-efficient taps across all properties, and reusing water at aquariums and in the Bellagio Fountain.”

8. Gray squirrel control: Study shows promise for effective contraceptive delivery system

“[… T]he feeders have a very high level of species-specificity. […] The bait and monitoring system developed and tested in the study demonstrated that […] “spring was the only season tested where female squirrels were more likely to visit bait feeders than males. Spring coincides with a peak in squirrel breeding and is therefore a good time to deliver a contraceptive."”

9. Returning Grazing Land to Native Forests Would Yield Big Climate Benefits

“[… S]trategically regrowing forests on land where cattle currently graze […] while intensifying production elsewhere could drastically cut greenhouse gas emissions, with little hit to global protein production, a new study shows.”

10. Interior Department Strengthens Conservation of American Bison Through New Agreement with Canada and Mexico

“Approximately 31,000 bison are currently being stewarded by the United States, Canada and Mexico with the goal of conserving the species and their role in the function of native grassland systems, as well as their place in Indigenous culture.”

"Namibia is the driest country in Sub-Saharan Africa, and home to two of the world’s most ancient deserts, the Kalahari and the Namib. The capital, Windhoek, is sandwiched between them, 400 miles away from the nearest perennial river and more than 300 miles away from the coast. Water is in short supply.

It’s hard to imagine life thriving in Windhoek, yet 477,000 people call it home, and 99 per cent of them have access to drinking water thanks to technology pioneered 55 years ago on the outskirts of the city. Now, some of the world’s biggest cities are embracing this technology as they adapt to the harshest impacts of climate change. But Namibia leads the way.

How did this come about? In the 1950s, Windhoek’s natural resources struggled to cope with a rapidly growing population, and severe water shortages gripped the city. But disaster forced innovation, and in 1968 the Goreangab Water Reclamation Plant in Windhoek became the first place in the world to produce drinking water directly from sewage, a process known as direct potable reuse (DPR). 

That may sound revolting, but it’s completely safe. Dr Lucas van Vuuren, who was among those who pioneered Windhoek’s reclamation system, once said that “water should not be judged by its history, but by its quality”. And DPR ensures quality. 

This is done using a continuous multi-barrier treatment devised in Windhoek during eight years of pilot studies in the 1960s. This process – which has been upgraded four times since 1968 – eliminates pollutants and safeguards against pathogens by harnessing bacteria to digest the human waste and remove it from the water. This partly mimics what happens when water is recycled in nature, but Windhoek does it all in under 24 hours...

“We know that we have antibiotics in the water, preservatives from cosmetics, anti-corrosion prevention chemicals from the dishwasher,” Honer explains. “We find them and we remove them.”

Honer adds that online instruments monitor the water continuously, and staff ensure that only drinking water that meets World Health Organisation (WHO) guidelines is sent to homes. If any inconsistencies are detected, the plant goes into recycle mode and distribution is halted until correct values are restored. 

“The most important rule is, and was, and always will be ‘safety first’,” says Honer.  The facility has never been linked to an outbreak of waterborne disease, and now produces up to 5.5m gallons of drinking water every day – up to 35 per cent of the city’s consumption.

Namibians couldn’t survive without it, and as water shortages grip the planet, Windhoek’s insights and experience are more important than ever.

Interest from superpowers across the globe

In recent years, delegations from the US, France, Germany, India, Australia, Singapore, and the United Arab Emirates have visited Windhoek seeking solutions to water shortages in their own countries. 

Megadrought conditions have gripped the US since 2001, and the Colorado River – which provides 40 million people with drinking water – has been running at just 50 per cent of its traditional flow. As a result, several states including Texas, California, Arizona and Colorado are beginning to embrace DPR.

Troy Walker is a water reuse practice leader at Hazen and Sawyer, an environmental engineering firm helping Arizona to develop its DPR regulations. He visited Windhoek last year. “It was about being able to see the success of their system, and then looking at some of the technical details and how that might look in a US facility or an Australian facility,” he said. “[Windhoek] has helped drive a lot of discussion in industry. [Innovation] doesn’t all have to come out of California or Texas.”

Namibia has also helped overcome the biggest obstacle to DPR – public acceptance. Disgust is a powerful emotion, and sensationalist ‘toilet to tap’ headlines have dismantled support for water reuse projects in the past. Unfortunately, DPR’s biggest strength is also its biggest weakness, as the speed at which water can re-enter the system makes it especially vulnerable to prejudice, causing regulators to hesitate. “Technology has never been the reason why these projects don’t get built – it’s always public or political opposition,” says Patsy Tennyson, vice president of Katz and Associates, an American firm that specialises in public outreach and communications.

That’s why just a handful of facilities worldwide are currently doing DPR, with Windhoek standing alongside smaller schemes in the Philippines, South Africa and a hybrid facility in Big Spring, Texas. But that’s all changing. Drought and increased water scarcity worldwide are forcing us to change the way we think about water. 

Now, the US is ready to take the plunge, and in 2025, El Paso Water will begin operating the first ‘direct to distribution’ DPR facility in North America, turning up to 10m gallons of wasterwater per day into purified drinking water – twice as much as Windhoek. San Diego, Los Angeles, California, as well as Phoenix, Arizona are also exploring the technology."

Of course, DPR is not a silver bullet in the fight against climate change. It cannot create water out of thin air, and it will not facilitate endless growth. But it does help cities become more climate resilient by reducing their reliance on natural sources, such as the Colorado River. 

As other nations follow in Namibia’s footsteps, Windhoek may no longer take the lead after almost six decades in front.

“But Windhoek was the first,” Honer reminds me. “No one can take that away.”"

I got emotional reading this. This is the kind of work we need. Working with nature instead of against it to reduce environmental disasters (in this case, it has the added benefit of helping groundwater levels). Working with indigenous groups to rewild land in a way that doesn’t cut human interaction out of the picture.
