Jan Wieringa

biologist, entomologist, botanist, with a passion for fieldwork

[Thomas Reis @peakaustria]

Chemical companies called her "hysterical" and an "unmarried spinster." She was dying of cancer while they attacked her. Her book started the environmental movement. They tried to destroy her. She won.

Rachel Carson was 54 years old, already one of America's most celebrated nature writers. Her book The Sea Around Us had spent 86 weeks on the New York Times bestseller list. With great Sketches! She was respected, successful, financially secure.
She could have retired comfortably, written more lyrical books about the ocean, enjoyed her success.
Instead, she wrote a book that would make her the most hated woman in corporate America.
Silent Spring hit bookstores in September 1962. Within months, it changed everything.
But the chemical industry—worth billions of dollars—decided to destroy her.
And Rachel Carson was dying. They just didn't know it yet.

Rachel had grown up loving nature. As a child in rural Pennsylvania, she'd explored forests and streams, collected specimens, dreamed of becoming a writer.
She'd become a marine biologist at a time when women in science faced constant discrimination. She'd worked for the U.S. Fish and Wildlife Service, writing bulletins about conservation, studying ocean ecosystems.
In 1951, she published The Sea Around Us—a poetic exploration of ocean science that became a surprise bestseller. Suddenly, Rachel Carson was famous. She could write full-time.
She was happy. Her life was good.
Then, in 1958, she received a letter from a friend, Olga Huckins. Olga described how state officials had sprayed DDT pesticide over her private bird sanctuary. Afterward, birds died by the hundreds. The sanctuary was silent.
Rachel had been hearing similar stories. DDT—dichlorodiphenyltrichloroethane—was being sprayed everywhere. On crops. On forests. On suburban neighborhoods to kill mosquitoes. Children played in yards where DDT had just been sprayed.
And birds were dying. Eagles. Falcons. Songbirds.
Their eggshells were thinning. Chicks couldn't survive. Entire species were declining.
Rachel started researching. What she found horrified her.

DDT and other synthetic pesticides were poison. Not just to insects—to everything.
They accumulated in soil, in water, in the bodies of animals and humans. They moved up the food chain, concentrating at higher levels. Birds of prey were especially vulnerable.
And nobody was regulating them. Chemical companies were making billions selling pesticides, claiming they were perfectly safe. Government agencies accepted the companies' safety claims without independent testing.
Rachel decided to write about it.
She knew it would be controversial. The chemical industry was powerful. But the truth needed to be told.
She spent four years researching. Reading scientific papers. Interviewing researchers. Documenting case after case of pesticide damage.
And then, in early 1960, she found a lump in her breast.
Cancer.

Rachel's doctors recommended aggressive treatment: surgery, radiation. The prognosis wasn't good. Breast cancer in 1960 was often fatal.
She could have stopped writing. Focused on her health. Told her publisher the book would be delayed indefinitely.
She didn't.
She had surgeries. She endured radiation treatments that left her weak and nauseated. She lost her hair.
And she kept writing.
She wrote in hospital beds. She wrote between treatments. She wrote through pain and exhaustion.
Because she knew: if she didn't finish this book, nobody would. And people needed to know the truth.
Silent Spring was completed in early 1962. It was published in September, first serialized in The New Yorker, then as a book.
The response was explosive.

Silent Spring opened with a haunting passage: a description of a town where spring came, but no birds sang. The orchards bloomed, but no bees pollinated. Children played in yards dusted with white powder, and then got sick.
It wasn't fiction. Rachel was describing what was already happening in towns across America.

Of heeft in ieder geval weinig zin dat in te voeren.

Deze mevrouw is #BBB statenlid. Ze beschermt eendennesten. Vervolgens bindt ze die eenden levend aan een stuk touw als lokeend om mee te jagen.

Wolven wil ze ook het liefst kapot schieten. Want die eten graag hert. Daardoor kan mevrouw minder herten afknallen. Om te BBBraken.

[Jan Wieringa @JanWieringa]

@MerijnKnibbe Maar in Yellowstone heeft de wolf juist voor een enorme verrijking van verschillende ecosystemen gezorgd. Wolven houden zich niet aan grenzen van de Hoge Veluwe, heel Nederland is hun terrein. En reken maar dat het ook op de Veluwe voor een positieve verandering gaat zorgen

Het ijzeren gordijn dat de ⁦@HogeVeluwe⁩ plaatste op het ecoduct Oud Reemst bij Otterlo heeft al genoeg slachtoffers gemaakt.En miljoenen Euro’s publiek geld over de balk gegooid. Hoogste tijd om de krachten te bundelen tegen dergelijk wanbeleid https://t.co/QE1zn1X10j 🐺📯

De schade die de landbouw veroorzaakt, is misschien wel groter dan de bijdrage van deze bedrijfstak aan de economie. Daarmee is de landbouw per saldo een welvaartsvernietigende activiteit, stelt @FrankKalshoven. Nederland heeft géén ruimteprobleem. Wel: irrationeel ruimtegebruik.

@faunabeschermin Oh, komt daar de term wappies vandaan.

NEW BEE JUST DROPPED! The sparkly blue Andrena androfovea might be the first of roughly 1700 Andrena species to be a specialist of the Solanaceae (tomato family), and has a sternal hairbrush for pollen collection! https://t.co/P79joC9gTu

Hij is er eindelijk! Het extra dikke themanummer van Entomologische Berichten: Wespen!
Een mooie afsluiter van het Jaar van de Wesp.

Bij onze leden is het themanummer inmiddels al op de mat gevallen, of anders gebeurt dat binnenkort 😄
Ook EB ontvangen? Word dan lid!
