Indonesia Bans the Burning
Of Peatland; Will Help Reduce CO2 Emissions
Indonesian President Joko Widodo announced a moratorium
earlier this week on the conversion of carbon-rich peatlands into agricultural land — a move that could prevent hundreds of millions of tons of CO2 from being emitted annually. In recent years, landowners and companies have been draining, drying, and often burning the country’s abundant peat-filled wetlands to make way for palm oil plantations and other farmland. Fires in 2015 caused more than a half-million people to be treated for respiratory problems and $16.1 billion in economic damage, according to the United Nations Environment Program
. Widodo’s moratorium protects peatlands of any depth and orders companies to restore any peatlands they have converted. "This regulation will be a major contribution to the Paris climate agreement and a relief to millions of Indonesians who suffer the effects of toxic haze from peat fires," said Nirarta Samadhi
, Indonesia country director for the World Resources Institute.

To Fight Air Pollution, Four
Cities Announce Ban on Diesel Cars By 2025
Four of the world’s largest cities announced Friday that they will ban diesel cars by 2025
in an effort to cut air pollution.
Traffic and smog in the outskirts of Paris.
Leaders from Paris, Madrid, Athens, and Mexico City made the declaration at the C40 Mayors Summit, a biennial meeting of civic leaders concerned about climate change. Toxic air is responsible for an estimated 3 million premature deaths
each year, according to recent research by the World Health Organization. While diesel engines burn fuel more efficiently and therefore release less carbon dioxide, they do produce nitrogen dioxide and particulates that can inflame and damage people’s lungs. “Mayors have already stood up to say that climate change is one of the greatest challenges we face,” said Anne Hidalgo, the mayor of Paris. “Today, we also stand up to say we no longer tolerate air pollution and the health problems and deaths it causes.”
Interview: At Standing Rock Protest,
A Battle Over Fossil Fuels and Land
For more than eight months, the Standing Rock Sioux Tribe in North Dakota has been leading a protest to stop an oil pipeline from
Kyle Powys Whyte
potentially threatening its drinking water and sacred sites. In many ways, the battle over the Dakota Access Pipeline is a traditional fight over Native American land rights. But as indigenous rights expert Kyle Powys Whyte sees it, the demonstration also points to the important role tribes have played in opposing fossil fuel energy projects in recent years. “Almost everywhere you go, tribes have taken direct action to protect their health and their cultures and their economies from the threats, as well as the false promises of, extractive industries,” he says. In an interview with Yale Environment 360
, Powys Whyte talks about the long history of coal and oil and gas development on native lands and why Standing Rock has become a lightning rod for opposition to fossil fuels.

as high as 30 times above World Health Organization guidelines, several news outlets reported
. Construction sites have been closed, operations at a coal-fired power station halted, diesel generators stopped, and officials are preparing to reinstate traffic restrictions, all to reduce smog levels across the city, which have reached their highest levels in 20 years. Officials say field burning on nearby farmland and fireworks from the recent Diwali festival helped worsen the smog conditions. Arvind Kejriwal, chief minister of Delhi, advised people to “stay home as much as they can [and] work from home,” The Guardian reported
. Indian business groups said 5 to 10 percent of the workforce in the city and surrounding areas had called in sick over the past week.

300 Million Children Breath
Pollution Six Times Worse Than Limit
Approximately 2 billion children live in communities where outdoor air pollution exceeds World Health Organization limits,
Global air pollution levels.
according to a new report by UNICEF
, the United Nations children’s aid group. That number includes 300 million children in areas with pollution levels six times higher than international guidelines. The pollution — caused by vehicle emissions, fossil fuels, dust, and burning waste — is a major contributing factor to the deaths of around 600,000 children under the age of five each year, the report warned. In South Asia, 620 million children live in areas with unsafe air pollution levels, followed by Africa with 520 million children, and East Asia and the Pacific region with 450 million children. The report comes just one week before world leaders converge in Marrakesh, Morocco for a United Nations meeting to discuss climate change and other related environmental issues, including air quality.

At Least 74,000 Americans Live
Near Oil and Gas Wells on Public Lands
A new online tool
mapping active oil and gas wells on U.S. public lands shows that at least 74,000 people in six states

live within a half-mile of drilling sites. That close proximity puts these people at increased risk of cancer, heart disease, and respiratory problems from natural gas leaking from the wells, said the Wilderness Society, which together with Earthworks helped create the tool. In Wyoming, for example, 15,869 oil and gas facilities
operate on public land, and some 4,000 people live within a half-mile of them — the range that airborne pollutants from wells, such as benzene, can easily travel. The mapping tool is being released at a time when scientists, environmental groups, and policymakers are ramping up calls to reduce and regulate natural gas leaks
from drilling and storage sites.

Scientists Find Clothing Sheds
Thousands of Plastic Fibers When Washed
A single load of laundry can shed more than 700,000 microscopic plastic fibers into water systems, according to a recent study
in the journal Marine Pollution Bulletin
. Many of these tiny plastic particles make it through sewage treatment plants and enter aquatic ecosystems such as rivers, lakes, wetlands, and oceans. The study looked at the breakdown of polyester, acrylic, and polyester-cotton fabrics washed in 86-104 degree Fahrenheit water with various detergents. It found that a 13-pound load of polyester-cotton laundry shed an estimated 137,951 plastic fibers, a load of polyester clothing 496,030 fibers, and acrylic fabric 728,789 fibers. Microplastic particles in waterways are often mistaken for food and eaten by marine life, with various health impacts. The research was conducted by scientists at Plymouth University in England.

and palm oil. In 2015, the fires — large enough to be visible from space — caused tens of billions of dollars in damage
, grounding hundreds of flights, closing schools, and creating respiratory problems for an estimated 500,000 Indonesians. This week, Indonesia’s highest Islamic council issued a fatwa, a legal religious ruling or decree, discouraging companies and individuals from using slash-and-burn agriculture. The council said any burning that “causes environmental damage… is illegitimate," Reuters reported
. Indonesia has the world’s largest Muslim community — 205 million people — making up 87.2 percent of its population.

Popular Insecticide Reduces
Queen Bees’ Ability To Lay Eggs, Study Finds
A new study has found neonicotinoids, the world’s most commonly used insecticide, cause queen honeybees to lay as much as two-thirds fewer eggs,

jeopardizing the health and stability of entire bee colonies. The research, conducted by scientists at the University of Nebraska-Lincoln and the University of Minnesota, was recently published in the journal Scientific Reports
. "The queens are… the only reproductive individual laying eggs in the colony," said lead author Judy Wu-Smart
. "If her ability to lay eggs is reduced, that is a subtle effect that isn't (immediately) noticeable, but translates to really dramatic consequences for the colony." The scientists also found colonies exposed to imidacloprid, a type of neonicotinoids, collected and stored less pollen than insecticide-free colonies, and removed just 74 percent of mite-infested or diseased pupae that can infect the entire hive, compared to 95 percent removal by unexposed bees.

Ragweed Allergies Could Double
In Europe as Global Temperatures Rise
The number of people suffering from ragweed allergies in Europe could more than double by mid-century due to climate change, according to a new study published in the journal
Environmental Health Prospectives
Ragweed (Ambrosia artemisiifolia)
. Warming global temperatures, the research found, will help increase the distribution of ragweed (Ambrosia artemisiifolia
) by making more areas of the continent suitable for its growth. Higher temperatures will also make growing seasons longer and increase pollen concentration in the air. Ragweed allergies, popularly known as hay fever, could impact 77 million people in Europe by 2041 to 2060, up from 33 million today, said the new study, led by scientists at the University of East Anglia. Allergies cost Europe $62 billion a year in lost productivity and are responsible for four million sick days worldwide, according to the news site Quartz

Shipping Noise Causes Whales
To Dive More Slowly and Forage Less
Ocean noise caused by shipping can cause humpback whales to dive more slowly and forage less frequently, according to new research
in the journal Biology Letters
A humpback whale diving.
A team of U.S. and U.K. researchers tagged 10 humpbacks in Stellwagen Bank National Marine Sanctuary, off the coast of Massachusetts, with devices that simultaneously tracked the whales’ movements and underwater noise. They found that as ship noise increased
, the whales dove 15 percent more slowly and did one-third fewer side-roll feedings, a foraging technique humpbacks use to catch fish near the seafloor. The findings are the latest addition to a growing list of negative impacts
from ocean noise on marine mammals, including disrupted communication, higher stress levels, and increased vulnerability as acoustic pollution masks predator movement. “Chronic impacts of even small reductions in foraging efficiency could affect individual fitness and translate to population-level effects on humpback whales,” the scientists wrote.

Melting Ice Sheet Could Expose
Abandoned U.S. Arctic Military Base

explore whether the U.S. could covertly deploy ballistic missiles from within the ice sheet, a mission known as Project Iceworm
. By 1967, the military had abandoned the base with little clean up, expecting it would be naturally entombed as snow and ice continued to accumulate on the Greenland ice cap. But warming global temperatures mean that ice loss in this frigid area of northwestern Greenland could exceed gains from new snowfall within 75 years, the study found. The hidden base could be exposed just a few decades later, along with all of the “physical, chemical, biological, and radiological wastes abandoned at the site,” the authors wrote.

Anthrax Outbreak in Northern
Russia Linked to Rising Global Temperatures
Soaring Arctic temperatures have released anthrax long frozen in the Russian tundra, sickening scores of nomadic herders, including 50 children, and killing one 12-year-old boy, according to news reports
. More than 2,300 reindeer have also died from the disease, known locally as the “Siberian plague.” Anthrax spores can lie dormant in frozen permafrost, animals, and human remains for hundreds of years, and eventually seep into groundwater during a thaw. The last anthrax outbreak in northern Russian happened 75 years ago, in 1941. Temperatures in the Yamal Peninsula, located 1,200 northeast of Moscow, reached 95 degrees F this past month. “Such anomalous heat is rare for Yamal, and that’s probably a manifestation of climate change,” Alexei Kokorin, head of WWF Russia’s climate and energy program, told The Guardian

Bacteria in Sea Ice Could Play
Role in Mercury Pollution in Oceans
Scientists have discovered bacteria living in Antarctic sea ice that could play a role in mercury contamination of fish, birds, and other marine species.
Antarctic sea ice.
The bacteria, Nitrospina
, can transform mercury found in sea ice — originating from sources such as coal-fired power plants — into the more toxic methylmercury. The heavy metal pollutant—which impacts brain development and can cause mental and physical ailments—accumulates in higher concentrations in marine life as it moves up through the food chain. The findings were published Monday in the journal Nature Microbiology
by scientists at the University of Melborne, the U.S. Geological Survey, and Lawrence Livermore National Lab. John Moreau, a geomicrobiologist at the University of Melbourne who helped lead the study, said in a statement
that the findings beg further study into the sources and behavior of mercury in the oceans, "particularly in a warming climate and when depleted fish stocks means more seafood companies are looking south."

Six Years After BP Spill,
Remaining Oil More Toxic Than Ever To Fish
Six years after the Deepwater Horizon drilling rig spilled nearly three million barrels of crude oil into the Gulf of Mexico, scientists have found that ultraviolet light
is transforming the remaining oil
into a more toxic substance that hinders the development of heart, eye, and brain function in fish. The research, led by scientists at the University of California, Riverside and the University of Miami, exposed embryos and larvae of mahi-mahi from the Gulf of Mexico to what they called weathered (exposed to years of sunlight) and un-weathered oil (taken from the drilling site) from the Deepwater Horizon spill in 2010. Compared to fish exposed to un-weathered oil, the fish exposed to the weathered oil experienced impaired eye and neurological function, reduced heart rates, and a buildup of excess fluid in the heart.

Hundreds of Deaths in 2003
Heat Wave Linked to Climate Change
A new study suggests that human-caused climate change could be responsible for a significant portion of the 70,000 deaths that occurred during the record-breaking 2003 European heat wave. The research, published in the journal Environmental Research Letters
, combined climate modeling with health data for hundreds of fatalities that summer. Climate change, the study found, increased the likelihood of heat-related losses by nearly 70 percent in Paris and 20 percent in London. Out of 735 heat-related deaths in Paris, 506 were attributable to global warming, as were 64 out of 315 deaths in London. "Until recently, whenever we talked about climate change we talked about the globally averaged increase in temperature of 1 degree and people just don't really know or frankly care about that," lead study author and Oxford University scientist Daniel Mitchell told InsideClimate News
. "But now… people can really start to understand that these are impacts we're seeing now, not in the future."

Paris Bans All Pre-1997
Cars During Weekdays to Fight Pollution
Starting this month, Paris is banning all cars built before 1997 from driving within city limits Monday through Friday in an effort to lower air pollution levels.
Commuter traffic in Paris.
Paris has been struggling with smog for years and its pollution levels have briefly topped those in Beijing. Similar to Mexico City and New Delhi
, Paris banned even- and odd-numbered license plates on alternating days to fight smog earlier this year. It has also championed cleaner transit options, such as bike- and electric car-sharing programs. Not everyone is enthused, however: The French consumer group 40 Million Drivers said the ban could impact up to 500,000 vehicle owners in and around Paris, particularly low-income families. "When you have an old car in France, it's because you don't have the money to buy a new one," Pierre Chasseray, the executive director of 40 Million Drivers, told NPR
. "Public transport is a solution, but it's not the solution for everybody."

Scientists Discover Contagious
Cancer in More Species of Shellfish
Last year, scientists discovered a type of contagious cancer in soft-shell clams in which free-floating cells transmitted the disease from one animal to another.
Now, a team of Columbia University researchers is reporting that contagious cancers in the ocean may be more common than previously thought
and can not only jump from animal to animal, but across species. According to the new study published in Nature, the leukemia-like cancer, known as disseminated neoplasia, has been found in three more species of bivalves: mussels, cockles, and golden carpet shell clams. The cancer cells were genetically distinct from their hosts, indicating they originated elsewhere. Transmissible cancer had previously been found in Tasmanian devils
and dogs, but there’s no indication that humans are at risk. “I would only worry deeply if I was a mollusk,” Stephen P. Goff, a molecular biologist at Columbia University and co-author of the study, told The New York Times

2015 Deadliest Year for
Environmentalists on Record, Finds Report
Last year was the deadliest year on record for environmentalists, according to a new report from Global Witness
, a nonprofit that tracks environmental and human rights abuses worldwide.
Indigenous people protest a dam in the Amazon.
One hundred and eighty-five people were killed trying to stop development of land, forests, and rivers in 16 countries in 2015 — equal to more than three people per week. The tally represents a 59 percent increase over 2014, and is double the number of journalists killed in the same period, according to the report. Environmentalists were most at risk in Brazil, the Philippines, and Columbia, which had 50, 33, and 26 killings last year, respectively. “This report sheds light on the acute vulnerability of indigenous people, whose weak land rights and geographic isolation make them particularly exposed to land grabbing for natural resource exploitation,” the Global Witness authors wrote. “In 2015, almost 40% of victims were indigenous.”
California Condor Population
Reaches New Heights in 2015
Earlier this year, the U.S. Fish and Wildlife Service announced what it called a milestone for the California condor: More chicks had hatched and fledged in the wild during 2015 than the number of condors that died,
bringing the total in the wild to 270. It was perhaps the most promising news about the condor in decades. After their numbers dropped to just 22 in the 1980s, the U.S. government began rounding up the birds for a last-ditch captive breeding program, then gradually released newly bred birds to the wild. The program was highly controversial, and the condors’ return to the wild over the past two and a half decades has been fraught with peril. But biologists have noted encouraging signs in recent years: The birds have expanded their range, are more likely to engage in wild behaviors, and have begun foraging for their own food.

Fish Choose Plastic Over
Zooplankton in Polluted Waters
Fish that grow up in waters full of plastic particles develop a taste for trash, choosing to eat plastic over zooplankton, their natural food source, according to a study published in the journal Science
The research, by ecologists at Uppsala University in Swedish, found larval perch from the Baltic Sea exposed to microplastic pollution (less than 5mm in size) had stunted growth, were less active, ignored the smell of predators, and experienced increased mortality rates. Plastic pollution has become a major problem in the world’s oceans, but scientists are just beginning to understand how these fragments can affect the health of marine species. “If early life-history stages of other species are similarly affected by microplastics, and this translates to increased mortality rates, the effects on aquatic ecosystems could be profound,” said ecologist Oona Lönnstedt
, lead author of the study.

Climate Change Could Be Making
Food Crops More Toxic, UN Report Says
As extreme weather increases in frequency and intensity, food crops are producing more chemical compounds that can be toxic to humans in large doses, according to a recent report by the United Nations Environment Programme
Crops such as wheat, maize, and soybeans generate these compounds as a natural response to environmental stressors, such as drought, floods or heat waves. But when consumed by humans for extended periods of time, they can cause illnesses like neurological diseases or cancer, according to the study. One example, the Thomson Reuters Foundation reports
, is nitrate. Drought slows down plants’ conversion of nitrates into amino acids and proteins, leading to a build up of the compound. When consumed in large quantities, nitrates stop red blood cells from transporting oxygen in the human body. "We are just beginning to recognize the magnitude of toxin- related issues confronting farmers in developing countries of the tropics and sub-tropics," the UNEP report noted.
For the Endangered American Eel,
A Long, Slippery Road to Recovery
The American eel isn’t just a U.S. native. It’s also indigenous to Greenland, Iceland, eastern Canada, and parts of Central and South America. Despite this expansive range, the International Union for Conservation of Nature lists the species as “endangered.”
It would be in even worse shape without the Delaware River, which flows unimpeded 330 miles through New York, Pennsylvania, New Jersey, and Delaware. Few, if any, eel refuges are more important, and management on the Delaware provides a global blueprint for eel recovery. The upper watershed is protected as a Wild and Scenic River corridor and as the water supply for New York City, and last June, New York State banned fracking in its part of the basin. Compare the Delaware with the nearby Susquehanna River, where the Conowingo Dam has wiped out 400 miles of eel habitat on the main river. But here and elsewhere eel recovery is underway.

Could This Straddling Bus Help
Solve China’s Air Pollution Problem?
With an estimated 20 million new drivers on the road each year, China has long struggled to control its CO2 emissions, air pollution, and traffic problems.
But a Beijing-based transit company is planning to test a new straddling bus this summer
that could provide some relief, according to Chinese news agency Xinhua. The bus, which can carry up to 1,400 passengers, hovers above the road, letting smaller vehicles pass underneath. Because it operates on existing roadways, the system is much cheaper to build than underground subways, while carrying the same number of people. The idea of a straddling bus has been around since 1969
, but has remained a far-fetched concept until recent years. A model of the system, designed by Transit Explore Bus, was unveiled at the International High-Tech Expo in Beijing this month. The company plans to build and test an actual straddling bus in Changzhou this summer.

Peru Declares Emergency to
Fight Mercury Pollution from Gold Mines
Peru has declared a 60-day emergency in the Amazon due to widespread mercury pollution from the region’s booming gold mining industry, the country's environment minister announced this week
Several studies have confirmed dangerously high levels of the neurotoxin in waterways, fish, and people living in the Madres de Dios region, near Peru’s southeast border. Members of the Harakmbut indigenous group, for example, have mercury levels in their bodies six times higher than what doctors deem safe
. Mercury is used to separate gold from ore, but it can have serious health impacts
, including damaging brain, kidney, and lung function. In illegal mining operations — which make up the majority of mines in the Peruvian Amazon — workers often handle the substance with bare hands, and dump excess mercury into nearby rivers. During the 60-day emergency period, the government will supply uncontaminated fish to local communities and set up mobile health clinics.

Brewing Company Creates
Edible Six-Pack Rings to Save Wildlife
Plastic six-pack rings have long been a nuisance to wildlife and ecosystems, fouling oceans and shorelines, and entangling and choking wildlife.
Now, a brewery in Florida has developed an edible version from the byproducts of making beer
, including wheat and barely. If not eaten by marine creatures, the six-pack ring biodegrades. Saltwater Brewery
3-D printed 500 of the holders in April and plans to scale up production to package all of its 400,000 cans of beer per month in the edible rings. The material is just as strong as traditional plastics, the brewery says, but is more expensive. The price would drop, however, as more companies use the edible rings, the brewery said. “We want to influence the big guys,” Chris Goves, president of Saltwater Brewery, said in a video about the new project. “And hopefully inspire them to get on board.”

Fumes from Farms Are
Top Source of Fine-Particle Pollution
Farms are the number one source of fine-particulate air pollution in the U.S., Europe, Russia, and China, according to new research published in the journal Geophysical Research Letters
Gases from fertilizers and livestock waste cling to emissions from cars, power plants, and factories to create solid particles less than 1/30th the width of human hair. Particles this size have been shown to penetrate deep into lungs, and cause an estimated 3.3 million deaths each year from illnesses like heart and pulmonary disease. Global climate action, however, could reduce this type of air pollution in the coming decades, says the new study, done by three Columbia University scientists. Cutbacks in energy consumption would mean that fumes from farms would have fewer emissions to which they could bond. This reduction in particulates would happen even if fertilizer use increases, the research says.

A Town Made Almost Entirely Out
Of Plastic Bottles is Being Built in Panama
Construction has begun on the world’s first town made almost entirely out of recycled plastic bottles. Located on Isla Colón in Panama, the village will consist of 120 houses and a lodge on 83 acres of tropical jungle.
The first two-bedroom home was built late last year, and is made from 10,000 plastic bottles pulled from Panama trashcans, roadsides, and beaches. The walls of the homes consist of steel cages filled with bottles and then encased in a concrete mix. They are flexible enough to withstand an earthquake, and insulating enough to keep the home up to 17 degrees F cooler than the jungle outside. Because there are so many recycled bottles on the island already, homes can be built quickly and cheaply, said Robert Bezeau, founder of the Plastic Bottle Village. “We are changing the world, without changing the Earth, one home at a time,” he says on the project’s website
