They don’t make the headlines the way charismatic animals such as rhinos and elephants do. But there are thousands of critically endangered plants in the world, and a determined group of botanists are ready to go to great lengths to save them.

To save plants that can no longer survive on their own, Steve Perlman has bushwhacked through remote valleys, dangled from helicopters, and teetered on the edge of towering sea cliffs. Watching a video of the self-described “extreme botanist” in action is not for the faint-hearted. “Each time I make this journey I’m aware that nature can turn on me,” Perlman says in the video as he battles ocean swells in a kayak to reach the few remaining members of a critically endangered species on a rugged, isolated stretch of Hawaiian coastline. “The ocean could suddenly rise up and dash me against the rocks like a piece of driftwood.”

When he arrives at his destination, Perlman starts hauling himself up an impossibly steep, razor-sharp cliff 3,000 feet above the sea without a rope, his fingers sending chunks of rock tumbling down to the waters below. Finally, he reaches the plants and painstakingly transfers pollen from the flowers of one to those of another to ensure that the species can perpetuate itself. At the end of the season, he will return to collect any seeds they were able to produce. Continue reading →

Cuttlefish are masters at altering their appearance to blend into their surroundings. But the cephalopods can no longer hide their inner thoughts, thanks to a technique that infers a cuttlefish’s brain activity by tracking the ever-changing patterns on its skin. The findings, published in Nature on 17 October1, could help researchers to better understand how the brain controls behaviour.
The cuttlefish (Sepia officinalis) camouflages itself by contracting the muscles around tiny, coloured skin cells called chromatophores. The cells come in several colours and act as pixels across the cuttlefish’s body, changing their size to alter the pattern on the animal’s skin.
The cuttlefish doesn’t always conjure up an exact match for its background. It can also blanket itself in stripes, rings, mottles or other complex patterns to make itself less noticeable to predators. “On any background, especially a coral reef, it can’t look like a thousand things,” says Roger Hanlon, a cephalopod biologist at the Marine Biological Laboratory in Woods Hole, Massachusetts. “Camouflage is about deceiving the visual system.” Continue reading →

George Washington was among the many fans of Newark cider, a long-missing treat now being recreated by a former ad man on a mission.

ASBURY, N.J. — Ironbound Hard Cider may seem an odd name for the business Charles Rosen has built here on 108 acres in central New Jersey. The farm, where a new taproom offers pastoral views of the still-ripening fruit, doesn’t appear to share much with the Ironbound, an industrial neighborhood 50 miles to the east in Newark.
Yet they do have common roots, thanks to four very old apple varieties now growing on Mr. Rosen’s land.

Mr. Rosen, the former chief executive of a Manhattan advertising agency that promoted Svedka vodka and Mike’s Hard Lemonade, wants to reintroduce Newark cider, an 18th- and 19th-century alcoholic drink once famously compared to Champagne.
Newark cider was both a point of pride and big business for the region — requested by name, reportedly lauded by George Washington and produced by dozens of Newark-area cideries with acres of orchards. The secret wasn’t a recipe, but the blending of a quartet of superior apples born in the region: Campfield, Poveshon, Granniwinkle and Harrison, the most celebrated of the four.

As a result of urbanization and then Prohibition, when many of the nation’s remaining cider orchards were destroyed, Newark cider hasn’t been made for at least a century. But after years of planning and planting — not to mention the accidental discovery of two lost apple trees and the investment of what Mr. Rosen called “100 percent of all the money I ever had in my entire life” — Ironbound Hard Cider is on the precipice of bringing it back.

In a village near Watamu, Kenya, a sea turtle accidentally caught by a fisherman was turned over to Local Ocean Conservation. Credit Amy Yee
These creatures have been around forever, more or less. Survived everything that nature threw at them over the epochs. Until mankind and its addiction to plastic. And now it is clear their days are numbered, so any initiative anywhere that tries to slow the clock and keep the species going, we are happy to hear about it and share on this platform. Thanks to Amy Yee for bringing this to our attention:
An organization on the coast of Kenya tries to persuade local residents to help return the trapped reptiles to the ocean, rather than sell their meat and shells for a living.

WATAMU, Kenya — The young hawksbill turtle was accidentally caught in a net in the Indian Ocean off Kenya’s coast.
The fisherman called Local Ocean Conservation, a nonprofit based in the town of Watamu that is the only turtle rescue and rehabilitation center on the East African seaboard. The hawksbill, critically endangered in this region, was a mere seven pounds; adults can weigh up to 160 pounds.
X-rays showed that the reptile’s intestinal tract was clogged with plastic. Hogaar, as Local Ocean named her, floated and couldn’t dive. Gas had built up in her innards after she had eaten small pieces of plastic mistaken for food such as jellyfish. Local Ocean staff members placed Hogaar in a rehab pool and gave her laxatives. She passed feces laced with shreds of packaging and had little appetite. After more than four months at Local Ocean, Hogaar died. A necropsy revealed her gut was also full of sharp shards of white, blue and pink plastic and tangles of blue and gray string.
Turtles are reptiles that have existed for at least 110 million years and survived the mass extinction that killed off dinosaurs. But today, sea turtles worldwide are threatened with extinction. And it’s estimated that only one of 1,000 turtle eggs laid survive to adulthood. Continue reading →
Spending time looking at the varying and beautiful images of our planet from above in Google Earth, zooming in and out at dizzying rates, I thought it would be interesting to compare all of these vistas at a fixed scale—to see what New York City, Venice, or the Grand Canyon would look like from the same virtual height. So, the following images are snapshots from Google Earth, all rectangles of the same size and scale, approximately three and a half miles (5.6 kilometers) wide by two miles (3.2 kilometers) tall—showing seven square miles (18.1 square kilometers, or 4,480 acres) of the surface of our planet in each view.

If you have been following the news recently, you may have noticed a report that indicates the urgency from climate change is greater than scientists previously thought. Everyone who cares has been digesting the science and we appreciate every effort to clarify what the science is saying. Fred Pearce, writing for Yale e360, has this:

The latest UN report on climate says reducing deforestation is crucial to slowing global warming. But researchers must first reconcile two contradictory sets of statistics on tree loss in order to determine whether promises made by nations to protect and restore forests are on target.
The world is losing trees faster than ever. An area the size of Italy disappeared last year. Or did it? New research suggests three-quarters of those lost forests may already be regrowing. That hardly means we are out of the woods. Fighting climate change and protecting biodiversity still needs a global campaign to reforest the planet. But it does suggest that, given the chance, nature will do much of the work. Continue reading →
Our school programming puts students at the center of the movement to restore oysters to New York City waters. Explore our Billion Oyster Classroom program, currently in 70+ New York City schools, and high school at the Harbor School.
Given all the challenges facing our oceans and waterways we are always heartened to hear of another initiative that involves collaboration between enterprise, youth and civic organizations. Click the image above or the one to the right to see what the Billion Oyster Project is doing in this regard. Thanks to National Public Radio (USA) for bringing this initiative to our attention:

Across New York City, more than 70 restaurants are tossing their oyster shells not into the trash or composting pile, but into the city’s eroded harbor. It’s all part of Billion Oyster Project’s restaurant shell-collection program.
The journey from trash to treasure begins after an oyster half shell is turned upside down and left on an icy tray. Once discarded, it joins hundreds of thousands of other half shells collected in blue bins and picked up (free of charge) from restaurants five days a week by Billion Oyster Project’s partner, The Lobster Place, a seafood supplier. The shells are trucked over to Brooklyn’s Greenpoint neighborhood and once a month are brought en masse to Governors Island in the heart of the New York Harbor, just yards away from both Brooklyn and Lower Manhattan. There, rolling shell hills sparkle in the sun while “curing” out in the elements for one year, a process that rids them of contaminants.

The shells then get a final cleaning and are moved to Billion Oyster Project’s hatchery at the Urban Assembly New York Harbor School, a public high school on Governors Island that offers technical and vocational training in the marine sciences. In an aquaculture classroom’s hatchery, student-grown oysters produce larvae in an artificially induced springtime environment. In one to two weeks, each larvae grows a “foot” — a little limb covered in a kind of natural glue — and then is moved to a tank full of the “cured” restaurant shells, which serve as anchors for all of those sticky feet. This phase is critical: If larvae can’t find a place to attach, they die. One reclaimed shell can house 10 to 20 new live oysters, depending on shell size. Continue reading →
Deniers, we already know you will find a way to see this from some other perspective, and we have given up trying to understand why you do that. But for everyone else, there is still time to understand the implications of this science. And there is no shame in using props to help learn. Thanks to Brad Plumer and Nadja Popovich for making sure we get the point, with clear graphical illustration, about what this recent study is saying and why every one of us should care:
The Earth has already warmed 1 degree Celsius (1.8 degrees Fahrenheit) since the 19th century. Now, a major new United Nations report has looked at the consequences of jumping to 1.5 or 2 degrees Celsius.
Half a degree may not sound like much. But as the report details, even that much warming could expose tens of millions more people worldwide to life-threatening heat waves, water shortages and coastal flooding. Half a degree may mean the difference between a world with coral reefs and Arctic summer sea ice and a world without them.
An additional half-degree of warming could mean greater habitat losses for polar bears, whales, seals and sea birds. But warming temperatures could benefit Arctic fisheries.
Extreme heat will be much more common worldwide under 2°C of warming compared to 1.5°C, with the tropics experiencing the biggest increase in the number of “highly unusual” hot days.

Every weekday, shortly after 11 a.m., a line forms at the Broadway and 38th Street location of Sweetgreen, the eco-conscious salad chain. By noon, the line has usually tripled in size. It often takes more than 15 minutes to get to the front.
The scene is similar at the Chop’t at 41st and Broadway, or the Dig Inn on West 38th, or the Just Salad one block south. In the heart of Midtown Manhattan, the evidence is hard to dismiss: Greens, once so unappetizing that parents all over the country had to beg and bribe their children to eat them, have never been hotter. (Almost as hot: their denser, younger cousin, grains.) Continue reading →
Valérie Chamberland swims like a dolphin, quickly and fluidly, and for most of the past hour she has been darting through the warm, shallow water off the Caribbean island of Curaçao. Now, she is dangling upside down, hovering above a pillow-sized brain coral. Her rubber fins twitch steadily overhead, and as she sips air from the aluminum tank on her back, a stream of bubbles rises from her regulator’s mouthpiece.
The reef spread below Chamberland isn’t one of those flashy, fluorescent gardens seen in calendar photos and nature documentaries. Only a few dozen yards from shore, it lies almost literally in the shadows of a stone jetty, a busy casino, and a Denny’s restaurant. The waters that surround it are murky, and most of its corals are brown and lumpy, sparsely accessorized with bright-purple vase sponges and waving, rusty-red sea fans. Continue reading →

This time of year, harvests finishing in many places, abundance is about to give way to the longer lean season. Maybe that is the perfect time to start thinking about stretching the ingredients at hand:

It is all too easy to romanticise the past, particularly with food. In Britain, rationing created a postwar generation that was very well-nourished, but also utterly bored by the meals it ate … or endured. Similarly, for all the criticism levelled at processed foods (“Don’t eat anything your great-grandmother wouldn’t recognise as food,” as the writer Michael Pollan famously advised), food has never been cheaper, nor easier to access and prepare. In 1957, as a proportion of their weekly income, UK households spent roughly double what they now spend on food – 33% of their money. There is a kind of liberation in the Pot Noodle.
Yet among many chefs and campaigning food writers, the sense persists that on a number of issues – particularly food waste, but also obesity, nutrition, cost, pleasure even – there is much to admire in how our grandparents ate. In an era of limited choice and tight budgets, they made a virtue of the necessity to cook with whatever fresh ingredients were available. “My grandparents didn’t cook ‘sustainably’, but they did cook every day, one of life’s best skills, and they didn’t throw leftovers away. To that extent, they were thrifty,” says Tom Hunt, the self-styled eco-chef and Guardian columnist.
To examine that idea, we asked a number of top chefs to choose a meal that encapsulates how their grandparents cooked and to explain how, in its frugal simplicity, it still influences them. Call it going back to the future. Continue reading →
Hiking in the Grand Canyon can be a perilous pursuit. Photograph by Pete McBride
Three years ago, in the course of thirteen months, the photographer Peter McBride and the writer Kevin Fedarko hiked from one end of the Grand Canyon to the other. They did it in eight sections, mainly so that McBride could shoot in different seasons. In all, it took them seventy-one days to cover two hundred and seventy-seven river miles and some eight hundred shoe-leather miles, through some of the continent’s roughest hiking terrain—“a whole lot of scratching around the rock puzzles in that giant abyss,” as McBride put it recently.
Before they set off, the Grand Canyon had been hiked nose to tail only nine times in recorded history. There is also a handful of obsessives who have chipped away at it, piece by piece, in the course of decades. “Maybe some crazy ancestral Puebloan did the whole thing, but that wouldn’t make logical sense—they wouldn’t have had any reason to,” McBride said.

McBride, a native Coloradan who shoots for National Geographic, has been documenting the Colorado River for a decade, sometimes from a perch in an ultralight aircraft. Fedarko, who lives in Flagstaff, Arizona, has guided on the river and is the author of “The Emerald Mile,” an account (with many historical tributaries) of a harrowing speed run of the Grand in a dory during the biggest flood in generations. (As it happens, Kenton Grua, the boatman in the book, was also the first person to walk the canyon, in 1976.) McBride and Fedarko have both become persistent, ardent advocates for preserving the place, in all its spellbinding, inhospitable glory, in abidance with Teddy Roosevelt’s famous dictum, issued during his one visit, in 1903: “Leave it as it is. Man cannot improve on it; not a bit.” Still, this was the first time, and surely the last, that either of them had tried to walk it. Continue reading →
What gets measured gets managed. In the realm of climate science, national governments have the scale and responsibility to be involved in measurement. But if a skeptic is in charge of the government apparatus, good luck with that. With the national government of one of the big carbon footprint countries abandoning science and dropping out of the fight to reduce climate change, one of that country’s biggest companies is stepping up to offer an alternative. It may be too little too late but under the circumstances we may have no choice but to cheer it on:
The company will begin estimating local carbon pollution from cities around the world.
In the next decade or so, more than 6,000 cities, states, and provinces around the world will try to do something that has eluded humanity for 25 years: reduce their emissions of greenhouse gases, which warm the atmosphere and cause climate change.
The city-level leaders overseeing this task won’t have the same tools available to their national peers. Most of them won’t have an Environmental Protection Agency (or its equivalent), a meteorological bureau, a team of military engineers, or nasa. So where will they start? Never mind how to reduce their city’s greenhouse-gas emissions; how will they know what’s spewing carbon dioxide in the first place?
Maybe Google will do it for them. Or, at least, do it with them.

In south-central Utah, where the topography is spectacular, desolate, and extreme, the pessimistic tradition in place-names runs strong. Head south from Poverty Flat and you’ll end up in Death Hollow. Head east from Dead Mare Wash and you’ll end up on Deadman Ridge, looking out toward Last Chance Creek and down into Carcass Canyon. During the Great Depression, when the whole state turned into a kind of Poverty Flat, the Civilian Conservation Corps sent a group of men to the region to carve a byway out of a virtually impassable landscape of cliffs and chasms. The men nicknamed the project Poison Road: so steep that a single drop would kill them. Midway up, the ridge they were following gaped open and plunged fifteen hundred feet to the canyon floor. They laid a span across it, and called it Hell’s Backbone Bridge.
Today, the entire route built by those men is known as Hell’s Backbone Road. Still largely unpaved, still treacherous in bad weather, it connects the town of Escalante to the tiny hamlet of Boulder, long reputed to be one of the most remote settlements in the continental United States. As late as 1940, the mail there was delivered via an eight-hour trek by mule team; the first lights did not flicker on until Christmas Eve, 1947. Until the nineteen-seventies, locals had to spend up to forty-eight hours in transit to obtain any number of essential goods and services: a new pair of socks, medical care, anything beyond an eighth-grade education.

Jim Dwyer, a New York Times reporter, and Josh Haner, a Times photographer, traveled to a Scottish archipelago in the North Atlantic to see how people are trying to save thousands of ancient structures.
Off the north coast of Scotland, Orkney’s soft green landscapes hold a trove of things from everyday life before history was written.
More than 3,000 archaeological sites — among them standing stone circles, Norse halls and a Neolithic tomb graffitied by Vikings — have endured for millenniums, scattered across the roughly 70 islands that make up the Orkney archipelago.
By Sarah Almukhtar | Source: Historic Environment Scotland Canmore. Note: Archaeological sites date from prehistoric times through the 20th century.
At Skara Brae, one of Europe’s best-preserved Stone Age villages, kitchens built around 3180 B.C. are fitted with hearths and cupboards, bedsteads and doors that could be bolted shut.
Today, in forays to remote spits of land, people are working to save some of these places for posterity from the climate changes accelerated by human activity.
About half of Orkney’s 3,000 sites, many built before Stonehenge or the pyramids, are under threat from those changes, according to the county archeologist. Some are already being washed away.

Since 1970, Orkney beaches have eroded twice as fast as in the previous century. Others that had been stable are now shrinking. Rains, falling heavier and more often, are dissolving the crusts of soil and sand packs that protect remnants of civilizations.
High in the Andes Mountains in Colombia, a reforestation project led by SavingSpecies works to protect one of the world’s most renowned bio hot spots.
WESTERN ANDES CLOUD FOREST, Colombia — Just before sunrise on a crisp summer morning high in a rain forest in Colombia’s Western Andes, the renowned ecologist Stuart Pimm gathered his research team over breakfast and made final plans for that morning’s journey to install motion-sensor cameras to monitor hummingbirds.
In just a few hours, the installations would be done by Andrea Kolarova, 20, who was here with other students from Duke University, where Dr. Pimm holds the Doris Duke Chair of Conservation. She was getting some advice from him and from Luis Mazariegos, founder of the Hummingbird Conservancy of Colombia.
Andrea Kolarova, a student from Duke, sets up a camera with help from Alexandra McManus, 11. Michael LaPorte
My daughter, Alexandra, 11, a student at Saxe Middle School in New Canaan, Conn., had also been invited to participate in the Colombia project, which is how I found myself for two weeks this summer living in a cabin in this remote mountainous territory. Although not far from the town of Jardin, which is about two and a half hours from Medellin, it takes a slightly harrowing hourlong ride in an ATV along a dirt switchback road to get here.
Ms. Kolarova’s hummingbird research will be used by Dr. Pimm’s organization, SavingSpecies, which he founded in 2007 to combat global warming using money he was awarded as a recipient of the Heineken Prize for Environmental Sciences a year earlier. SavingSpecies works with local organizations around the world to buy land with the goal of restoring forests that have been destroyed, often because of logging, agricultural expansion, mining and oil extraction, and protecting the species that are under threat as a result.

Scientists have finally confirmed that a weird ribbed oval called Dickinsonia is an animal.
A Dickinsonia fossilILYA BOBROVSKIY / AUSTRALIAN NATIONAL UNIVERSITY
While it sits in place, petrifying, waiting, the world around it changes. The Earth’s landmasses merge into a single supercontinent before going their separate ways. In the ocean, animal life explodes; for the first time, the world is home to eyes, shells, and mouths. Living things invade the land, coating it first in thin films of moss and lichens, and then covering it in huge forests. Insects rise, into existence, and then into the skies. A dinosaur empire rises and falls. Mammals finally take over, and one of them—a human by the name of Ilya Bobrovskiy—finally unearths the fossilized ribbed oval from its resting place.

America’s social infrastructure is falling apart, and it’s hurting democracy.
Every four years, the American Society for Civil Engineers issues grades for the nation’s infrastructure. In the most recent evaluation, released in 2017, America’s overall infrastructure score was a D+, the same as in 2013. Although seven systems, including hazardous waste and levees, received modestly better grades than in the previous assessment, transit and solid waste, among others, did worse. Aviation (D), roads (D), drinking water (D), and energy (D+), retained their miserably low scores. Continue reading →
