Environmental Working Group publishes its “Dirty Dozen” list for 2020

Zee Krstic, GOOD HOUSEKEEPING

Each spring, the Environmental Working Group (also known as the EWG) publishes a list of fruits and vegetables that experts at the nonprofit say contain elevated levels of pesticides that may be concerning. Now known as the Dirty Dozen list to health experts and in-the-know shoppers, the list has long called conventional farming methods into question, especially as the EWG also publishes a competing list called the Clean Fifteen that highlights produce containing little to no pesticides when grown conventionally.

Monarch butterfly population critically low on California coast – again

Associated Press, THE GUARDIAN

Study finds 29,000 butterflies, compared with 4.5 million during the 1980s, as experts point to habitat destruction

The western monarch butterfly population wintering along California’s coast remains critically low for the second year in a row, a count by an environmental group released Thursday showed.

The count of the orange-and-black insects by the Xerces Society, a not-for-profit environmental organization that focuses on the conservation of invertebrates, recorded about 29,000 butterflies in its annual survey. That’s not much different than last year’s tally, when an all-time low 27,000 monarchs were counted.

“We had hoped that the western monarch population would have rebounded at least modestly, but unfortunately it has not,” said Emma Pelton, a monarch conservation expert with the Xerces Society.

By comparison, about 4.5 million monarch butterflies wintered in forested groves along the California coast in the 1980s. Scientists say the butterflies are at critically low levels in the Western US due to the destruction of their milkweed habitat along their migratory route as housing expands into their territory and use of pesticides and herbicides increases.

Researchers also have noted the effect of climate change. Along with farming, climate change is one of the main drivers of the monarch’s threatened extinction, disrupting an annual 3,000-mile migration synced to springtime and the blossoming of wildflowers.

‘Like sending bees to war’: the deadly truth behind your almond-milk obsession

Annette McGivney, THE GUARDIAN

Bees are essential to the functioning of America’s titanic almond industry – and billions are dying in the process

Dennis Arp was feeling optimistic last summer, which is unusual for a beekeeper these days.

Thanks to a record wet spring, his hundreds of hives, scattered across the central Arizona desert, produced a bounty of honey. Arp would have plenty to sell in stores, but more importantly, the bumper harvest would strengthen his bees for their biggest task of the coming year.

Like most commercial beekeepers in the US, at least half of Arp’s revenue now comes from pollinating almonds. Selling honey is far less lucrative then renting out his colonies to mega-farms in California’s fertile Central Valley, home to 80% of the world’s almond supply.

But as winter approached, with Arp just months away from taking his hives to California, his bees started getting sick. By October, 150 of Arp’s hives had been wiped out by mites, 12% of his inventory in just a few months. “My yard is currently filled with stacks of empty bee boxes that used to contain healthy hives,” he says.

This shouldn’t be happening to someone like Arp, a beekeeper with decades of experience. But his story is not unique. Commercial beekeepers who send their hives to the almond farms are seeing their bees die in record numbers, and nothing they do seems to stop the decline.

A recent survey of commercial beekeepers showed that 50 billion bees – more than seven times the world’s human population – were wiped out in a few months during winter 2018-19. This is more than one-third of commercial US bee colonies, the highest number since the annual survey started in the mid-2000s.

Beekeepers attributed the high mortality rate to pesticide exposure, diseases from parasites and habitat loss. However, environmentalists and organic beekeepers maintain that the real culprit is something more systemic: America’s reliance on industrial agriculture methods, especially those used by the almond industry, which demands a large-scale mechanization of one of nature’s most delicate natural processes.

Urgent new ‘roadmap to recovery’ could reverse insect apocalypse

Patrick Greenfield, THE GUARDIAN

Phasing out synthetic pesticides and fertilisers and aggressive emission reductions among series of solutions outlined by scientists

The world must eradicate pesticide use, prioritise nature-based farming methods and urgently reduce water, light and noise pollution to save plummeting insect populations, according to a new “roadmap to insect recovery” compiled by experts.

The call to action by more than 70 scientists from across the planet advocates immediate action on human stress factors to insects which include habitat loss and fragmentation, the climate crisis, pollution, over-harvesting and invasive species.

Phasing out synthetic pesticides and fertilisers used in industrial farming and aggressive greenhouse gas emission reductions are among a series of urgent “no-regret” solutions to reverse what conservationists have called the “unnoticed insect apocalypse”.

Alongside these measures, scientists must urgently establish which herbivores, detritivores, parasitoids, predators and pollinators are priority species for conservation, according to a new paper published in Nature Ecology & Evolution. The animals are crucial to the healthy functioning of ecosystems by recycling nutrients, serving as pollinators and acting as food for other wildlife.

The paper comes amid repeated warnings about the threat of human-driven insect extinction causing a “catastrophic collapse of nature’s ecosystems”, with more than 40% of insect species declining and a third endangered, according to the first worldwide scientific review, published in February 2019.

Cotton on: the staggering potential of switching to organic clothes

Rebecca Smithers, THE GUARDIAN

ost Britons underestimate the full environmental impact of cotton, thinking it takes only 314 litres of water to make a cotton T-shirt – which is only 12% of the true figure of 2,700 litres, according to a new report out today.

Yet buying a certified organic cotton T-shirt rather than an ordinary one would save a staggering 2,457 litres of water – enough for one person to drink eight glasses of water a day for three and a half years.

Consumers are being urged to save water in the supply chain by buying organic cotton T-shirts in a new study from the Soil Association – the trade body that licenses organic products and promotes organic farming, as well as the environmental charity Hubbub.

Two in five Britons also said that while they care about the environment, it has not occurred to them that the manufacture of their clothing might have a negative impact on the planet, according to the new research.

Within the fashion industry, more than half of garments sold in the UK are made from cotton, meaning that switching conventional cotton to more sustainable cotton alternatives continues to present one of the biggest opportunities for retailers to reduce their environmental impact.

Cotton is a notoriously thirsty crop as detailed in the report. Growing cotton accounts for 69% of the water footprint of textile fibre production; just one kilogram of cotton takes as much as 10,000-20,000 litres of water to produce.

The World Economic Forum has identified water scarcity as one of the top 10 global risks to society over the next 10 years, yet the bulk of cotton is grown in countries that are already facing severe water stress.

However, growing cotton organically uses significantly less (up to 91%) water than conventional cotton, the report says. In addition, conventional cotton uses approximately 16% of the world’s insecticides and 7% of pesticides.

Sonoma County restricts use of Roundup, other synthetic pesticides

Guy Kovner, THE PRESS DEMOCRAT

Sonoma County this week became the fourth local government agency in the country to restrict use of synthetic pesticides on public land, joining a wave of cities and counties across the nation that are banning a chemical deemed by some to cause cancer.

Santa Rosa, Windsor and Sonoma have previously precluded application of synthetic weedkillers on public property, with Sonoma specifically targeting glyphosate, the main ingredient in Roundup, the widely used herbicide manufactured by Monsanto.

At least 38 California cities and counties in California have now adopted bans on synthetic pesticides, along with jurisdictions in 22 other states from coast to coast, according to Baum, Hedlund, Aristei & Goldman, a Los Angeles-based law firm that has won three cases against Monsanto with $2.4 billion in damages.

The pesticide rebellion gained momentum in 2017, when glyphosate was added to California’s Proposition 65 list of cancer-causing chemicals.

Megan Kaun, a Sebastopol resident who developed the county measure in collaboration with Supervisor Lynda Hopkins, began her campaign in 2015 when she found out glyphosate was being sprayed on a playground near her former home in Santa Rosa. Last August, the city prohibited use of synthetic weedkillers at dozens of parks, buildings and medians.

Windsor banned synthetic pesticides from public property last year, and the town of Sonoma barred use of glyphosate in April.

The newest regulation applies to lands maintained by county agencies, including water, parks, roads and the open space district, requiring them to eliminate use of synthetic herbicides, insecticides and fungicides to the “maximum extent practicable.”

Our love of almonds is seriously jeopardizing honeybees

Paige Embrey, HUFF POST

In January, with the almond bloom in California’s orchards a month away, beekeepers across the country were fretting over their hives. A lot of their bees were dead or sick. Beekeepers reported losing as much as half their hives over the winter.

Jack Brumley, a California beekeeper, said he’d heard of people losing 80% of their bees. Denise Qualls, a bee broker who connects keepers with growers, said she was seeing “a lot more panic occurring earlier.”

Rumors swirled of a potential shortage; almond growers scrambled to ensure they had enough bees to pollinate their valuable crop, reaching out to beekeepers as far away as Florida, striking deals with mom-and-pop operations that kept no more than a few hundred bees. NPR’s “All Things Considered” aired a segment on the looming crisis in the almond groves.

By May, it was clear that California’s almond growers — who supply 80% of the world’s almonds — had successfully negotiated the threat of a bee shortage and were expected to produce a record crop of 2.5 billion pounds, up 10% from last year, according to the U.S. Department of Agriculture.

But the panic, it turns out, was justified. The results of this year’s annual Bee Informed Partnership survey, a collaboration by leading research labs released Wednesday, found that winter colony losses were nearly 38%, the highest rate since the survey began 13 years ago and almost 9% higher than the average loss.

The panic underscored a fundamental problem with the relationship between almonds and bees: Every year, the almond industry expands while the population of honeybees, beset by a host of afflictions, struggles to keep pace.

Sonoma County supervisors eye pesticide restrictions on public land

Guy Kovner, THE PRESS DEMOCRAT

Sonoma County supervisors are scheduled to consider a proposal Tuesday to ban synthetic pesticides on county property open to public use and in other “no synthetic spray zones” to be determined this year.

The proposal specifically precludes use of synthetic herbicides, insecticides and fungicides on county agency campuses, sidewalks, plazas, playing fields, playgrounds and county-maintained libraries.

It also would apply to Sonoma Water, the Agricultural and Open Space District, the Community Development Commission and the Transportation and Public Works Department, requiring them to eliminate pesticide use “to the maximum extent practicable.”

The Transportation and Public Works Department is experimenting with organic alternatives to manage roadside vegetation that poses a safety risk or can contribute to flooding, said Dan Virkstis, a department spokesman.

Private land would be exempt from the ban. The county is prohibited from regulating pesticide use on private property, a county staff report said.

California to ban pesticide chlorpyrifos

Brian Melley, ASSOCIATED PRESS

The nation’s most productive agricultural state moved Wednesday to ban a controversial pesticide widely used to control a range of insects but blamed for harming brain development in babies.

The move cheered by environmentalists would outlaw chlorpyrifos after scientists deemed it a toxic air contaminant and discovered it to be more dangerous than previously thought. California Environmental Secretary Jared Blumenfeld said it’s the first time the state has sought to ban a pesticide and the move was overdue.

“This pesticide is a neurotoxin, and it was first put on the market in 1965,” Blumenfeld said. “So it’s been on the shelf a long time, and it’s past its sell-by date.”

The decision comes after regulators in several states have taken steps in recent years to restrict the pesticide used on about 60 different crops in California, including grapes, almonds and oranges. Hawaii banned it last year, and New York lawmakers recently sent a measure to the governor outlawing use of the pesticide.

DowDuPont, which produces the pesticide, said it was disappointed with the decision and that farmers who rely on the pesticide say it will hurt their ability to control insects.

Plummeting insect numbers ‘threaten collapse of nature’

Damian Carrington, THE GUARDIAN

“Unless we change our ways of producing food, insects as a whole will go down the path of extinction in a few decades,” they write. “The repercussions this will have for the planet’s ecosystems are catastrophic to say the least.”

The analysis, published in the journal Biological Conservation, says intensive agriculture is the main driver of the declines, particularly the heavy use of pesticides. Urbanisation and climate change are also significant factors.

The world’s insects are hurtling down the path to extinction, threatening a “catastrophic collapse of nature’s ecosystems”, according to the first global scientific review.

More than 40% of insect species are declining and a third are endangered, the analysis found. The rate of extinction is eight times faster than that of mammals, birds and reptiles. The total mass of insects is falling by a precipitous 2.5% a year, according to the best data available, suggesting they could vanish within a century.

The planet is at the start of a sixth mass extinction in its history, with huge losses already reported in larger animals that are easier to study. But insects are by far the most varied and abundant animals, outweighing humanity by 17 times. They are “essential” for the proper functioning of all ecosystems, the researchers say, as food for other creatures, pollinators and recyclers of nutrients.
