When the U.S. Environmental Protection Agency (EPA) recently released and then abruptly withdrew a draft document on the cancer risks posed by the pesticide glyphosate, Monsanto jumped at the chance to say that its signature chemical had been exonerated.
The EPA says it has more work to do. In the meantime, the Environmental Working Group took a closer look at the science underpinning the World Health Organization’s decision last year to classify glyphosate as a “probable carcinogen.”
Here’s what we found: A growing body of research is finding a link between glyphosate exposure and non-Hodgkin lymphoma, especially with some specific subtypes of the cancer.
In the now-retracted document, the EPA initially found insufficient evidence to classify glyphosate as a probable carcinogen, citing some studies that haven’t been able to associate glyphosate exposure with higher risks of non-Hodgkin lymphoma.
The trouble is, there are many kinds of non-Hodgkin lymphoma and by trying to link a whole group of different cancers to glyphosate exposure, the EPA draft may have missed associations with specific kinds of non-Hodgkin lymphoma.
One such study, published in 2008 by Swedish researchers, found that exposure to glyphosate tripled the risk of a subtype of non-Hodgkin called small lymphocytic lymphoma.
This alarming link may be masked when the data is lumped in with other kinds of non-Hodgkin lymphoma that have different causes.
Moreover, there is often a lag time between exposure to a carcinogen and when people find out they have cancer. The same Swedish study found that a person’s risk of being diagnosed with non-Hodgkin lymphoma began to rise more than 10 years after exposure.
This is disturbing, given that the use of glyphosate in the U.S. exploded 20-fold over the past two decades and most of the herbicide has been sprayed in just the past 10 years. We may be just beginning to see the public health consequences of this herbicide.
Studies that take a closer look at specific types of cancer show alarming evidence of the potential for glyphosate to increase cancer risk. They should not be ignored.

Here are three new films to watch this Earth Week that will transport you from pole to pole and introduce you to the scientists and activists working to save our shared home.
1. The Year Earth Changed
Where to Watch: Apple TV+
When to Watch: From April 16
The coronavirus pandemic has brought home the stakes of humanity's impact on the environment. But the lockdowns also proved how quickly nature can recover when humans give it the space. Birds sang in empty cities, whales surfaced in Glacier Bay and capybara roamed the South American suburbs.
The Year Earth Changed captures this unique year with footage from more than 30 lockdowned cities between May 2020 to January 2021. Narrated by renowned wildlife broadcaster David Attenborough, the film explores what positive lessons we can take from the experience of a quieter, less trafficked world.
"What the film shows is that the natural world can bounce back remarkably quickly when we take a step back and reduce our impact as we did during lockdown," executive producer Alice Keens-Soper of BBC Studios Natural History Unit told EcoWatch. "If we are willing to make even small changes to our habits, the natural world can flourish. We need to learn how to co-exist with nature and understand that we are not separate from it- for example if we closed some of our beaches at for a few weeks during the turtle breeding we see that it can make a huge difference to their success. There are many ways that we can adapt our behavior to allow the natural world to thrive as it did in lockdown."
2. After Antarctica
Where to Watch: San Francisco International Film Festival
When to Watch: 12 a.m. PST April 9 to 11:59 p.m. April 18
In 1989, Will Steger led an international team of six scientists and explorers to be the first humans to cross Antarctica by dogsled. Steger and his team weren't just in it for the adventure. They also wanted to draw attention to the ways in which the climate crisis was already transforming the icy continent and to rally support for the renewal of the Antarctic Treaty, which would keep the continent safe from extractive industries.
In After Antarctica, award-winning filmmaker Tasha Van Zandt follows Steger 30 years later as he travels the Arctic this time, reflecting on his original journey and once again bringing awareness to changes in a polar landscape. The film intersperses this contemporary journey with footage from the original expedition, some of which has never been seen before.
"Will's life journey as an explorer and climate activist has led him not only to see more of the polar world than anyone else alive today, but to being an eyewitness to the changes occurring across both poles," Van Zandt told EcoWatch. "But now, these changes are happening in all of our own backyards and we have all become eyewitnesses. Through my journey with Will, I have learned that although we cannot always control change, we can change our response. I feel strongly that this is a message that resonates when we look at the current state of the world, as we each have power and control over how we choose to respond to hardships, and we all have the power to unite with others through collective action around a common goal."
After Antarctica is available to stream once you purchase a ticket to the San Francisco International Film Festival. If you miss it this weekend, it will screen again at the Minneapolis St. Paul International Film Festival from May 13 to May 23.

3. The Race to Save the World
Where to Watch: Virtual Cinema
When to Watch: From Earth Day, April 22
While many films about the climate crisis seek to raise awareness about the extent of the problem, The Race to Save the World focuses on the people who are trying to stop it. The film tells the story of climate activists ranging from 15-year-old Aji to 72-year-old Miriam who are working to create a sustainable future. It follows them from the streets to the courtroom to their homes, and explores the impact of their advocacy on their personal lives and relationships.
Emmy award-winning documentary filmmaker Joe Gantz told EcoWatch that he wanted to make a film about climate change, but did not want to depress viewers with overwhelming statistics. Instead, he chose to inspire them by sharing the stories of people trying to make a difference.
"Unless millions of people take to the streets and make their voices heard for a livable future, the politicians are not going to get on board to help make the changes needed for a sustainable future," Gantz told Ecowatch. "I think that The Race To Save The World will energize and inspire people to take action so that future generations, as well as the plants, animals and ecosystems, can survive and thrive on this planet."
Check back with EcoWatch on the morning of Earth Day for a special preview of this inspiring film!
