Monsanto Demands World Health Organization Retract Report That Says Roundup Is Linked to Cancer

Last week, the UN's World Health Organization (WHO) released a report, compiled by a team of scientists, that said glyphosate—sold by Monsanto in the herbicide Roundup—was probably linked to cancer.

This week, Monsanto is demanding the WHO retract the report, essentially repudiating years of research by multiple scientists. Monsanto is claiming the report was biased and that glyphosate products like Roundup are safe when the directions are followed. The company says that the WHO report contradicts regulatory findings, which can, of course, be influenced by politics and lobbying. So far, WHO has not responded.

"We question the quality of the assessment," Philip Miller, Monsanto vice president of global regulatory affairs, told Reuters. "The WHO has something to explain."

Miller claimed that the WHO's International Agency for Research on Cancer (IARC) was provided by Monsanto with information on glyphosate's safety, and that it ignored Monsanto's input.

That response indicates a level of panic on Monsanto's part because the report could hit it where it hurts—its profits. Its Roundup, formulated to be used on GMO or "Roundup Ready" crops engineered to be resistant to it, is the most widely used herbicide in the world. Originally introduced in the early ’70s to control weeds, it took off when the planting of GMO crops skyrocketed in the last 15 years. The U.S. Geological Survey (USGS) estimated that glyphosate use in the U.S. increased from about 20 million pounds in 1992 to 110 million pounds in 2002 to more than 280 million pounds in 2012.

What Monsanto is demanding is the equivalent of declaring a person innocent because there is insufficient evidence to prove his guilt. The WHO report did not claim definitely the glyphosate causes cancer, but rather that multiple scientific studies have suggested a link.

"For the herbicide glyphosate, there was limited evidence of carcinogenicity in humans for non-Hodgkin lymphoma," the study said. "The evidence in humans is from studies of exposures, mostly agricultural, in the U.S., Canada and Sweden published since 2001. In addition, there is convincing evidence that glyphosate also can cause cancer in laboratory animals. Glyphosate also caused DNA and chromosomal damage in human cells. One study in community residents reported increases in blood markers of chromosomal damage after glyphosate formulations were sprayed nearby."

It points out that "limited" does not mean "nonexistent" as Monsanto wants it to declare. When a substance is categorized as "probably" carcinogenic to humans, it says "there is limited evidence of carcinogenicity in humans and sufficient evidence of carcinogenicity in experimental animals. Limited evidence means that a positive association has been observed between exposure to the agent and cancer but that other explanations for the observations could not be ruled out. This category is also used when there is limited evidence of carcinogenicity in humans and strong data on how the agent causes cancer."

And, as the Reuters article points out, Monsanto says such studies are invalid, but critics say they merit attention. According to Dave Schubert, head of the cellular neurobiology laboratory at the Salk Institute for Biological Studies in La Jolla, California, "There are a number of independent, published manuscripts that clearly indicate that glyphosate ... can promote cancer and tumor growth. It should be banned."

Several leading public interest organizations agree with Schubert and today urged the Obama administration to “weigh heavily” the WHO's recent conclusion that glyphosate is a “probable human carcinogen.” The groups believes that “As a result of WHO’s rigorous and independent review, the link between glyphosate and cancer has now been greatly strengthened."

In a letter to Gina McCarthy, administrator of the U.S. Environmental Protection Agency, JLI, Consumers Union, Center for Food Safety, Environmental Working Group and Natural Resources Defense Council, among others, called the WHO announcement “extremely timely, as EPA is preparing to issue its preliminary risk assessment of the widely used herbicide under the Federal Insecticide, Fungicide and Rodenticide Act.”

“Consumers deserve to know which foods are made with GMOs considering it’s their dollars that are largely driving the use of this dangerous herbicide,” said Gary Hirshberg, the chairman of the board for the Just Label It campaign. “This new evidence that the main pesticide used on GMO crops is a 'probable human carcinogen' is even more reason consumers should have the right to know what’s in their food."

One proponent of the "glyphosate is absolutely safe" narrative is former environmentalist/current environmental contrarian/sometime Monsanto consultant Dr. Patrick Moore, who was interviewed by filmmaker Paul Moreira for a French TV documentary. He not only insisted "[Roundup] is not dangerous to humans, he also said "You can drink a whole quart of it and it won't hurt you." But when Moreira said, "You want to drink some? We have some here," Moore responded "I'd be happy to ... not really, but I know it would't hurt me," and walked off the set when Moreira repeated his offer, calling the him an "idiot."

This College Could Become the First 100% Renewable Campus in U.S.

As a growing number of U.S. cities make pledges towards 100 percent renewables, it's easy to forget that the entire state of Hawaii set this important benchmark three years ago when it mandated that all of its electricity must come from renewable sources no later than 2045.

To help the Aloha State meet this ambitious commitment, in 2015, the University of Hawaii (UH) and the Hawaiian Legislature set a collective goal for the university system to be "net-zero" by Jan. 1, 2035, which means the total amount of energy consumed is equal to the amount of renewable energy created.

Silver Nanoparticles in Clothing Wash Out, May Be Toxic

By Sukalyan Sengupta and Tabish Nawaz

Humans have known since ancient times that silver kills or stops the growth of many microorganisms. Hippocrates, the father of medicine, is said to have used silver preparations for treating ulcers and healing wounds. Until the introduction of antibiotics in the 1940s, colloidal silver (tiny particles suspended in a liquid) was a mainstay for treating burns, infected wounds and ulcers. Silver is still used today in wound dressings, in creams and as a coating on medical devices.

Study Finds Timely Emissions Reductions Could Prevent 153 Million Air Pollution Deaths This Century

One of the roadblocks to swift action on climate change is the human brain's tendency to focus on threats and stimuli that are an obvious and noticeable part of their everyday lives, rather than an abstract and future problem, as Amit Dhir explained in The Decision Lab.

Now, a study published in Nature Climate Change Monday shows that acting quickly to curb greenhouse gas emissions would also reduce the air pollution that is already a major urban killer, thereby saving millions of lives within the next 40 years.

Katharine Hayhoe Reveals Surprising Ways to Talk About Climate Change

By Katie O'Reilly

Katharine Hayhoe isn't your typical atmospheric scientist. Throughout her career, the evangelical Christian and daughter of missionaries has had to convince many (including her pastor husband) that science and religion need not be at odds when it comes to climate change. Hayhoe, who directs Texas Tech's University's Climate Science Center, is CEO of ATMOS Research, a scientific consulting company, and produces the PBS Kids' web series Global Weirding, rose to national prominence in early 2012 after then-presidential candidate Newt Gingrich dropped her chapter from a book he was editing about the environment. The reason? Hayhoe's arguments affirmed that climate change was no liberal hoax. The Toronto native attracted the fury of Rush Limbaugh, who encouraged his listeners to harass her.

Kinder Morgan Pipeline Protest Grows: Arrests Include a Greenpeace Founder, Juno-Nominated Grandfather

By Andy Rowell

Just because you get older, it doesn't mean you cannot stop taking action for what you believe in. And Monday was a case in point. Two seventy-year-olds, still putting their bodies on the line for environmental justice and indigenous rights.

Early Monday morning, the first seventy-year-old, a grandfather of two, and former nominee for Canada's Juno musical award, slipped into Kinder Morgan's compound at one of its sites for the controversial Trans Mountain pipeline and scaled a tree and then erected a mid-air platform with a hammock up in the air.

German monk and theologian Martin Luther probably said it best: "Beer is made by men, wine by God." It's true—the world loves its wine. Americans, in fact, downed close to a billion gallons of it in 2016. But winemakers create a lot of waste when they produce all that vino, most of it in seeds, stalks and skins.
