1. Scientists Invent Healthier More Sustainable Chocolate

“The new chocolate recipe from researchers at ETH Zurich uses more materials from the cocoa pod that are usually discarded, including more of the pulp as well as the inner lining of the husk, known as the endocarp. [���] The resulting chocolate also [was “deliciously sweet” and] had 20% more fibre and 30 percent less saturated fat than average European dark chocolate[, and] it could enable cocoa farmers [to] earn more from their crops.”

2. Vermont Is Coming for Big Oil, Making It Pay for Decades of Climate Pollution

“Legislators in Montpelier are on the brink of enacting the "Climate Superfund Act," modeled after the federal Superfund law, that seeks to make oil, gas and coal companies pay for damages linked to historical greenhouse gas emissions. […] Companies would be held liable for the costs associated with […] floods and heat waves, along with losses to biodiversity, safety, economic development and anything else the treasurer deems reasonable[, that were caused by their emissions].”

3. Important bird habitat now protected in the Rocky Mountain Trench

“Grassland-reliant species in the Rocky Mountain Trench now have more protected habitat thanks to a new [270-hectare] conservation area near Cranbrook. […] About one-third of the Skookumchuck Prairie Conservation Area is forested[…,] Most of the site is a dry grassland[…, and] Three hectares of wetlands add to the landscape diversity and offer crucial benefits to wildlife and water systems in the area. This conservation gem also provides habitat for endangered American badger and excellent winter range for elk, mule deer and white-tailed deer.”

4. Lemur Week marked by 70th breeding success

“A wildlife park has celebrated its 70th lemur breeding success ahead of a week raising money to help save the endangered primates. […] The park's open-air Madagascar exhibit is home to 31 free-roaming lemurs and was officially opened in 2008. […] Females are only sexually receptive for just one or two days a year, leaving a small window of opportunity for males to father offspring. […] The two playful siblings, one female and one male, were born to father Bernard and mother Hira.”

5. Innovative material for sustainable building

“Researchers introduce a polymer-based material with unique properties. This material allows sunlight to enter, maintains a more comfortable indoor climate without additional energy, and cleans itself like a lotus leaf. The new development could replace glass components in walls and roofs in the future.”

6. Isle of Wight eagles don't pose threat to lambs as feared

“While there had previously been fears that the eagles would feed on livestock, such as lambs, the project has found no evidence of this. [… “W]hite-tailed eagles effectively steal meals from other predatory birds[, which is] a really important ecological role that had been lost within the landscape and is being restored.” [… The birds’] population was boosted by a chick last year – the first time the species has bred in England in 240 years.”

7. Breakthrough discovery uses engineered surfaces to shed heat

“Cheng's team has found a way to lower the starting point of the [Leidenfrost] effect by producing a surface covered with micropillars. […] The discovery has great potential in heat transfer applications such as the cooling of industrial machines and surface fouling cleaning for heat exchangers. It also could help prevent damage and even disaster to nuclear machinery.”

8. New malaria vaccine delivered for the first time

“A total of 43,000 doses arrived by air today from UNICEF, and another 120,000 are scheduled to show up in the coming days. […] They're the first vaccines designed to work against a human parasite. […] Across four African countries, these trials showed a 75% reduction in malaria cases in the year following vaccination of young children. […] The Serum Institute of India, who will be manufacturing the new vaccine, says a hundred million doses will likely be available to countries by the middle of next year.”

9. Urban gardening may improve human health: Microbial exposure boosts immune system

“"One month of urban indoor gardening boosted the diversity of bacteria on the skin of the subjects and was associated with higher levels of anti-inflammatory cytokines in the blood. The group studied used a growing medium with high microbial diversity emulating the forest soil," [… whereas] the control group used a microbially poor peat-based medium. [… N]o changes in the blood or the skin microbiota were seen. […] “This is the first time we can demonstrate that meaningful and natural human activity can increase the diversity of the microbiota of healthy adults and, at the same time, contribute to the regulation of the immune system."”

10. Cities Are Switching to Electric Vehicles Faster Than Individuals

“[M]ost large cities have adopted some kind of climate goal, and some of them are buying EVs for their municipal fleets at a faster rate than the general public. And that progress could speed up as more EVs enter the market and as cities get educated about grant funding and tax incentives that were passed over the last four years.”

DESMOND HAS TERRIBLE TASTE IN FOOD

He drinks his coffee black, not for the energy or to be pretentious, but just because he genuinely fucking prefers it that way. He prefers the taste of strong alcohol, give him a can of 4loko, and he will drink it like plain water. He eats overly spicy food (like so spicy it just straight ruins the flavor), not even just because he has a high spice tolerance, just because he likes it???? He eats canned soup straight out the can without even heating it up, actually, he refuses to heat up any kind of leftovers and just eats them cold even if it's something that absolutely should not be eaten cold. Everyone refuses to eat at his house after they saw him throw back a can of cold baked beans without even blinking.

Great waterer to help our livestock

[probablyasocialecologist]

The global food economy is massively inefficient. The need for standardized products means tons of edible food are destroyed or left to rot. This is one reason more than one-third of the global food supply is wasted or lost; for the U.S., the figure is closer to one-half. The logic of global trade results in massive quantities of identical products being simultaneously imported and exported—a needless waste of fossil fuels and an enormous addition to greenhouse gas emissions. In a typical year, for example, the U.S. imports more than 400,000 tons of potatoes and 1 million tons of beef while exporting almost the same tonnage. The same is true of many other food commodities and countries. The same logic leads to shipping foods worldwide simply to reduce labor costs for processing. Shrimp harvested off the coast of Scotland, for example, are shipped 6,000 miles to Thailand to be peeled, then shipped 6,000 miles back to the UK to be sold to consumers. The supposed efficiency of monocultural production is based on output per unit of labor, which is maximized by replacing jobs with chemical- and energy-intensive technology. Measured by output per acre, however—a far more relevant metric—smaller-scale farms are typically 8 to 20 times more productive.

"It is 70 years since AT&T’s Bell Labs unveiled a new technology for turning sunlight into power. The phone company hoped it could replace the batteries that run equipment in out-of-the-way places. It also realised that powering devices with light alone showed how science could make the future seem wonderful; hence a press event at which sunshine kept a toy Ferris wheel spinning round and round.

Today solar power is long past the toy phase. Panels now occupy an area around half that of Wales, and this year they will provide the world with about 6% of its electricity—which is almost three times as much electrical energy as America consumed back in 1954. Yet this historic growth is only the second-most-remarkable thing about the rise of solar power. The most remarkable is that it is nowhere near over.

To call solar power’s rise exponential is not hyperbole, but a statement of fact. Installed solar capacity doubles roughly every three years, and so grows ten-fold each decade. Such sustained growth is seldom seen in anything that matters. That makes it hard for people to get their heads round what is going on. When it was a tenth of its current size ten years ago, solar power was still seen as marginal even by experts who knew how fast it had grown. The next ten-fold increase will be equivalent to multiplying the world’s entire fleet of nuclear reactors by eight in less than the time it typically takes to build just a single one of them.

Solar cells will in all likelihood be the single biggest source of electrical power on the planet by the mid 2030s. By the 2040s they may be the largest source not just of electricity but of all energy. On current trends, the all-in cost of the electricity they produce promises to be less than half as expensive as the cheapest available today. This will not stop climate change, but could slow it a lot faster. Much of the world—including Africa, where 600m people still cannot light their homes—will begin to feel energy-rich. That feeling will be a new and transformational one for humankind.

To grasp that this is not some environmentalist fever dream, consider solar economics. As the cumulative production of a manufactured good increases, costs go down. As costs go down, demand goes up. As demand goes up, production increases—and costs go down further. This cannot go on for ever; production, demand or both always become constrained. In earlier energy transitions—from wood to coal, coal to oil or oil to gas—the efficiency of extraction grew, but it was eventually offset by the cost of finding ever more fuel.

As our essay this week explains, solar power faces no such constraint. The resources needed to produce solar cells and plant them on solar farms are silicon-rich sand, sunny places and human ingenuity, all three of which are abundant. Making cells also takes energy, but solar power is fast making that abundant, too. As for demand, it is both huge and elastic—if you make electricity cheaper, people will find uses for it. The result is that, in contrast to earlier energy sources, solar power has routinely become cheaper and will continue to do so.

Other constraints do exist. Given people’s proclivity for living outside daylight hours, solar power needs to be complemented with storage and supplemented by other technologies. Heavy industry and aviation and freight have been hard to electrify. Fortunately, these problems may be solved as batteries and fuels created by electrolysis gradually become cheaper...

The aim should be for the virtuous circle of solar-power production to turn as fast as possible. That is because it offers the prize of cheaper energy. The benefits start with a boost to productivity. Anything that people use energy for today will cost less—and that includes pretty much everything. Then come the things cheap energy will make possible. People who could never afford to will start lighting their houses or driving a car. Cheap energy can purify water, and even desalinate it. It can drive the hungry machinery of artificial intelligence. It can make billions of homes and offices more bearable in summers that will, for decades to come, be getting hotter.

But it is the things that nobody has yet thought of that will be most consequential. In its radical abundance, cheaper energy will free the imagination, setting tiny Ferris wheels of the mind spinning with excitement and new possibilities.

This week marks the summer solstice in the northern hemisphere. The Sun rising to its highest point in the sky will in decades to come shine down on a world where nobody need go without the blessings of electricity and where the access to energy invigorates all those it touches."

Just wanted to pitch my two cents in response to the previous anon! Hi friend, I know for a lot of us who get our food shrink wrapped and packaged at the grocery store it’s mind boggling to even imagine there’s a healthy way of animal husbandry.

I grew up in The Big City™️ but was raised by my grandparents. They grew up farming (just crops, their families were too poor to own livestock or purchase meat/milk/eggs) and taught me to have an incredible respect for where food comes from. We grew our own crops in the tiny backyard, composted, and did aquaculture even before I knew what it was. We bought our smaller meat from the local butcher minimally processed. You had to debone and process the whole chicken, fish, rabbit, frogs, etc. Grandpa traded his veggies for different fruits with the other oldies. Grandma made her own wine and yogurt. And I’ve worked and volunteered at animal shelters and wildlife rescue/rehab centers growing up. I still compost nearly all of my food waste. Even then, I didn’t truly understand the extent to which a properly cared for animal farm could be healthy and ethical.

Until I met one of my previous partners that is. They grew up in an incredibly rural area on a family farm that had animals, including a herd of cows for meat. They hunted, but always to protect the livestock and made use of the animals they killed/sold them to others in town who would. It seemed so counterintuitive to my sensibilities and raised my hackles at first. How could you say you love animals and do that? But I began asking questions…for hours and hours because it was nothing I’d been exposed to.

The way they and their family cared for/revered their animals seemed almost religious to me when I first encountered it. From the time they were kids, it was always the animals’ chores first. You woke up but fed and milked the cows before you made yourself breakfast. They made blankets for the animals and read to them. You gave the herd everything they needed and then some. If something in the barn needed fixing, that would happen first before new windows for the house. The animals had their own things and toys and treats. It was love! There were never cattle prods or whips or any of the machinery you associate with industrial farming. The animals would greet them happily every morning. They loved and trusted their people back enough to be naughty a way a pampered cat is. It really sunk in when I stood next to a cow for the first time — there’s nothing that would stop that animal from harming you, especially if you were a kid, unless it respected you and loved you back.

(They once told me the story of how some large predator like a bear or wolf tried to sneak into the pasture at night. The family woke up there next morning to a furry pancake that had been utterly stomped into the ground by the herd.)

A whole lifetime later, they can still remember the names, personalities, and stories of all the animals they raised. I would get bored and try to list off random names as a game to see if they ever had an animal called that, actually. But the thing that initially shocked (and stuck with me the most) was that when they’d take an older cow to the butcher, they would get packages of meat back labeled with that animal’s name. But it wasn’t ever scary or traumatizing for the kids. They always knew where food was from. Sometimes they were even there helping when that animal was born in the barn. What that did was give them an incredible sense of care, respect, and duty for those animals. When they had dinner that night, they would say grace and mean it in a way you only could if you viewed that animal as an equal family member. I was raised religious, but had never heard grace said like that, with that amount of genuine intent until I ate dinner with them. It used to be just something I did, just going through the motions.

That being said, yes it would probably be the most bio energy efficient/less emissions heavy if the whole world shifted away from a meat-based diet. But ideal isn’t always realistic/something we can achieve overnight. Meat alternatives are often expensive or time consuming to prepare (like beans/legumes). The way I see it, this blog is part of a harm reduction approach in facilitating an appreciation/love/education for livestock and then encouraging people to seek out more mindful sources of meat, like some local farms. We’ve seen time and time again, shame/blame are far less effective in getting people to re-examine their worldviews than education and love.

thank you so much for this ask, this is so so so so so lovely!!! i feel like a lot of people that arent farmers or dont have farmers in their family dont really understand just how much love is there.
