Are Sea Cucumbers a Cleanup Solution to Fish Farm Pollution?

Seafood farm operators are breeding and deploying sea cucumbers to vacuum up the massive amounts of fish waste that pose a major problem for their industry. It is part of an effort to redesign fish farms with multiple species so that they work more like natural ecosystems.

Off the coast of the Hawaiian Island of Kauai, an underwater metropolis bustles. Sea turtles glide lazily through the surf while schools of fluorescent yellow butterflyfish weave between basketball-size sea urchins and sharp corals.

But Dave Anderson isn’t distracted by the otherworldly charm of the coral reef — he’s here on a mission. Around 70 feet below the surface, he finds his prize: a red sea cucumber. Continue reading

#CargoUnderSail #RethinkShipping

The Climate Crisis Gives Sailing Ships a Second Wind

Cargo vessels are some of the dirtiest vehicles in existence. Can a centuries-old technology help to clean them up?

In February, 1912, Londoners packed a dock on the River Thames to gawk at the Selandia, a ship that could race through the water without any sails or smokestacks. Winston Churchill, then the minister in charge of the British Royal Navy, declared it “the most perfect maritime masterpiece of the twentieth century.” But, as the Selandia continued its journey around the world, some onlookers were so spooked that they called it the Devil Ship…

The history is a fun read, so continue to the whole story here. But then, take a closer look at the company featured in the article:

Our Story

Over the course of 20 years working in the maritime industry Cornelius Bockermann witnessed first hand how humans adversely affect our environment. He knew something had to change. In 2013, he moved with his family to Cairns and shipped all their possessions from Germany to their new home in Australia. Through the process of shipping his own goods he experienced the disconnect between commerce and environmental preservation. Upon learning of plans to expand fossil fuel based shipping along the Queensland coast and amongst the Great Barrier Reef he knew he had to act. The question became how do you offer businesses and consumers a sustainable option in shipping?

Cargo Under Sail is the answer and the Dutch schooner named the AVONTUUR is the vessel to start it.

We are a passionate collective of individuals working to create a supply chain that merges the relationship between commerce and preservation. We are restless and can no longer wait for others to make a change.

Our Mission Zero

To eliminate pollution caused by shipping cargo.

We have a five-stage approach:

1. Raise Awareness about the environmental destruction caused by the shipping industry

2. Model a clean shipping future with our AVONTUUR

3. Sell premium AVONTUUR products to support the ongoing operation of the project.

4.  Establish a demand for products shipped by sail

5. Build a modern sail cargo fleet

Developing Clean Energy At Ambitious Scale

It is not every day that your country is given good odds on an important project of such an ambitious scale.

The Economist’s WOODBINE column has this to say about it:

America’s chance to become a clean-energy superpower

Getting the most ambitious energy and climate laws in American history through Congress was not easy. Now comes the hard part

The future catches you in unexpected places. Drive down Interstate 95, the highway running along America’s Atlantic coast, into south-eastern Georgia and you will find signs and rest stops named after pecans and peaches. Continue reading

Sailing Cargo Ships, Again

Old school (sailing cargo ships) becoming the new trend is as good as news gets these days:

Cargo ships powered by wind could help tackle climate crisis

Shipping produces much of the world’s greenhouse gases but new technology offers solutions to cut fuel use

Cars, trucks and planes get plenty of blame for helping drive the climate crisis, but shipping produces a large portion of the world’s greenhouse gases, as well as nitrogen oxides and sulphur pollution because ships largely use cheap heavy fuel oil. Continue reading

Seaweed, Seafood, Plastics & Fodder

Globally, seaweed production has grown by nearly 75 percent in the past decade.

After news of the blob coming our way, here is another useful seaweed story in excellent interactive format:

Seaweed Is Having Its Moment in the Sun

It’s being reimagined as a plastic substitute, even as cattle feed. But can seaweed thrive in a warming world?

For centuries, it’s been treasured in kitchens in Asia and neglected almost everywhere else: Those glistening ribbons of seaweed that bend and bloom in cold ocean waves. Continue reading

Urban Jungle, Covered In Literary Review

We look forward to Ben Wilson’s new book, as reviewed here:

Where the Streets are Paved with Goldenrod

No one, you would think, aspires to be a night-soil man. Yet in the late 1950s, Shi Chuangxiang’s labours in the latrines of Beijing briefly won him national praise. He was proclaimed a socialist hero and met the head of state. Back then, human excreta mattered, so much so that gangs fought for the plummest spots. Why? Because cities, until relatively recently in human history, were a part of healthy ecosystems that operated according to the principles of nutrient exchange: take, use, return, all in neat equilibrium. The spoils of Mr Shi (who was nicknamed ‘Stinky Shit Egg’), collected at a time when synthetic plant food was not widely available in China, became the organic fertiliser that was intended to power the country’s Great Leap Forward in agriculture.

Fred Pearce brings us news from the European-African axis of renewable energy:

In Scramble for Clean Energy, Europe Is Turning to North Africa

In its quest for green energy, Europe is looking to North Africa, where vast solar and wind farms are proliferating and plans call for submarine cables that will carry electricity as far as Britain. But this rush for clean power is raising serious environmental concerns.

Solar panels in sun-rich North Africa generate up to three times more energy than in Europe. And North Africa has a lot more room for them than densely populated Europe. Continue reading

Bio-Based Gains

Scientists at San Diego-based Genomatica, which is developing a plant-based nylon. GENOMATICA

We have been watching and waiting for this range of products to have their day, and Jim Robbins delivers an up to date account that gives hope:

From Lab to Market: Bio-Based Products Are Gaining Momentum

Propelled by government investment and shareholder demand, manufacturers are pushing to get bio-based products into the marketplace. These new materials — made from plants, fungi, and microbes — aim to replace those that contain toxins and are difficult to recycle or reuse.

In the 1930s, the DuPont company created the world’s first nylon, a synthetic polymer made from petroleum. The product first appeared in bristles for toothbrushes, but eventually it would be used for a broad range of products, from stockings to blouses, carpets, food packaging, and even dental floss.

Nylon is still widely used, but, like other plastics, it has environmental downsides: it is made from a nonrenewable resource; its production generates nitrous oxide, a potent greenhouse gas; it doesn’t biodegrade; and it sheds microfibers that end up in food, water, plants, animals, and even the clouds.

Now, however, a San Diego-based company called Genomatica is offering an alternative: a so-called plant-based nylon made through biosynthesis, in which a genetically engineered microorganism ferments plant sugars to create a chemical intermediate that can be turned into nylon-6 polymer chips, and then textiles. The company has partnered with Lululemon, Unilever, and others to manufacture this and other bio-based products that safely decompose. Continue reading

Coffee Capsules Reconsidered

‘It hurts to know that we create so much waste.’ Composite: The Guardian/Getty Images/NASA

We have been clearly on one side of this, but now thanks to Cecilia Nowell and the Guardian we acknowledge a possible reason to reconsider:

Are coffee pods really eco-friendly? The truth behind the surprising findings

Coffee capsules notoriously produce waste – but some experts maintain that reducing how much coffee you use, even with a pod, can decrease emissions

If you drink one of the 2bn cups of coffee consumed each day worldwide, you may have seen headlines last month celebrating the coffee pod, a single-serving container – typically made of plastic or aluminum – that can be inserted into a machine to brew a cup of coffee. Continue reading

EV Boom

At this point we should not be surprised but the momentum is still stunning:

Electric Vehicles Keep Defying Almost Everyone’s Predictions

It is striking that in the same year that Tesla’s stock price dropped by about two-thirds, destroying more than $700 billion in market value, the global market for electric vehicles — which for so long the company seemed almost to embody — actually boomed. Continue reading

Glass Half Full, NOLA Community Recycling

This youthful organization, new to us but old enough to have proof of concept is, in their own words, crushing it:

Turning glass waste into useable sand and cullet.

We collect and convert NOLA’s glass bottles — which have been crammed into our landfills for decades — into functional products: sand and glass cullet. These precious materials have an array of applications, from coastal restoration to flood prevention to eco-construction.

Converting glass into sand & glass cullet

Our recycling process involves diverting used glass products from landfills and sorting, sifting, and ultimately converting them into sand products ranging from super soft, beach-like sand to glass gravel. The final products are used for coastal restoration projects, disaster relief efforts, eco-construction, new glass products, and so much more. The applications for sand are truly endless.

Is Cruise Travel Evolving In A Way That Is Good For The Planet?

Cruise ship tourism is unfortunately not disappearing as we might have hoped. Are the ships evolving to be more environmentally and socially responsible? Our thanks to Maria Cramer for asking and attempting to answer the question:

How Green is Your Cruise?

As cruise companies head into their busiest season, they say they have ambitious plans to curb greenhouse emissions and find cleaner sources of fuel. But critics say the progress is too slow.

In the Caribbean, many cruise companies have bought islands and turned them into private resorts for the exclusive use of cruise passengers who cavort in enormous wave pools, rush down 135-foot water slides with names like Daredevil’s Peak, and zip-line across wide beaches. Continue reading

Imposing On Pastoral Beauty To Capture Wind’s Power

Pinnacle turbines dot the skyline in Keyser, West Virginia, where, according to Andrew Cosner, a twenty-one-year-old technician, some residents remain hostile to the new wind farm: “They say it ruins the landscape and it’s ugly.”

It is to each of us whether we find the view attractive or not, and there was a time when I found large man-made structures an imposition on pastoral beauty.

Smith stands in the nacelle of one of the turbines just before daybreak.

As time passes I find myself drawn more to such a view as that in the photo above as a signal of progress.  It is not because the view is in a place far away from me– on the mountain ridge above where I live there is a row of such turbines and I am constantly gazing at that horizon. Published in the print edition of the November 28, 2022, issue of the New Yorker, with the headline “Blade Runners,” D.T. Max provides some context, but the photos do the heavy lifting:

Precision Fermentation’s Implied Potential

Illustration: Eleanor Shakespeare/The Guardian

It is the first time we are seeing these two words together, and George Monbiot has this to say about the potential implied:

Embrace what may be the most important green technology ever. It could save us all

Never mind the yuck factor: precision fermentation could produce new staple foods, and end our reliance on farming

So what do we do now? After 27 summits and no effective action, it seems that the real purpose was to keep us talking. If governments were serious about preventing climate breakdown, there would have been no Cops 2-27. The major issues would have been resolved at Cop1, as the ozone depletion crisis was at a single summit in Montreal. Continue reading

Greenhouse By Joost

We have not heard news of Joost Bakker in over a decade, so Max Veenhuyzen’s profile and introduction to the documentary previewed above is most welcome:

“The most destructive things we humans do,” says Joost Bakker, “is eat.”

In terms of sentences that grab your attention, the introduction to new Australian documentary Greenhouse by Joost is right up there. Then again, Bakker – a multi-disciplinary designer, no-waste advocate and the film’s eponymous protagonist – has long been something of a provocateur. Continue reading

‘It’s got nasty’: the battle to build the US’s biggest solar power farm

A community turns on itself over the aptly named Mammoth solar project, a planned $1.5bn power field nearly the size of Manhattan

When proposals for the largest solar plant ever conceived for US soil started to gather pace – a plan that involves spearing several million solar panels into the flat farmland of northern Indiana – something in Connie Ehrlich seems to have snapped. Continue reading

Plus De Ce Méfait, S’il Vous Plaît

As an energy crisis looms, Paris officials have taken steps to reduce nighttime lights, as have conservation-minded Parkour practitioners. Mauricio Lima for The New York Times

We cannot presume to cheer this type of mischief anywhere else, but considering the origin story of parkour, and the incentives for activism, it seems fitting for the City of Lights:

With Leaps and Bounds, Parkour Athletes Turn Off the Lights in Paris

As an energy crisis looms, nimble young activists are using superhero-like moves to switch off wasteful lights that stores leave on all night.

Paris— After taking a few steps back to get a running start, Hadj Benhalima dashed toward the building, pushed against its wall with his foot, propelled himself upward and stretched out his arm.

At the peak of his leap, he flipped off a light switch, more than 10 feet off the ground. A click sound rang out, and the bright lights of a nearby barbershop went off instantly.

“Oooh,” his friends cheered, as Mr. Benhalima, a thin 21-year-old dressed all in black, landed back on the sidewalk. It was the second store sign he had turned off on a recent nighttime tour across Paris’s upscale neighborhoods. Many more would follow as he soared up and dropped back down across the city.

Reducing Emissions & Living Well

We normally think of Costa Rica to answer this question, but it is in good company:

No greater challenge faces humanity than reducing emissions without backsliding into preindustrial poverty. One tiny country is leading the way.

Let’s say you live in the typical American household. It doesn’t exist, not in any sense except in a data set, but it’s easy enough to imagine.

“We learn to live with less here,” says a former bank analyst, Ignacio Estrada, who had decided to take a 75 percent pay cut to return home. “And it’s made my life better.”

Maybe it’s your aunt’s, or your neighbor’s, or a bit like your own. Since more than half of us live outside big cities, it’s probably in a middle-class suburb, like Fox Lake, north of Chicago.

You picked it because it’s affordable and not a terrible commute to your job. Your house is about 2,200 square feet — a split-level ranch, perhaps. You’re in your mid-30s and just welcomed your first child. Together with your partner you make about $70,000 a year, some of which goes toward the 11,000 kilowatts of electricity and 37,000 cubic feet of natural gas you use to heat the house, play video games and dry your clothes. You take six or seven plane flights a year, to visit your mom after her surgery or attend a conference, and drive about 25,000 miles, most of which you barely register anymore, as you listen to Joe Rogan or Bad Bunny. Maybe twice a month you stop at Target and pick up six or seven things: double-sided tape, an extra toothbrush, an inflatable mattress. Continue reading

Pushing Decarbonizing Technology Via Industrial Policy

Thanks to Yale e360:

Beyond Biden’s Climate Plan, a New Industrial Revolution Is Needed

The new U.S. climate plan is historic and will pump billions of dollars into advancing the transition away from fossil fuels. But a more far-reaching, innovative approach is needed to push forward the radically new technologies that will be required to decarbonize the economy.

For all the great news in the Biden administration’s massive new climate spending plan, the hardest work of transforming the economy to stop global warming lies ahead. That’s because nearly all the money in the $369 billion plan will be spent on technologies that American companies already know how to deploy, such as solar farms, making buildings more efficient, and developing networks of electric vehicle charging systems.

Doing a lot more of the same will undoubtedly bring down emissions faster. But deep decarbonization requires a transformation of the American economy that will demand a much more active effort to push the technological frontier and build new industries so emissions can be driven to zero.
