Glyphosate Is Anything But Safe


Under our industrial agricultural methods, virtually all of our major crops are being grown with GMO seeds designed to withstand glyphosate, more commonly known by its trade name Roundup®. Seeds are planted. After they sprout, the fields are poisoned, up to three different times, to kill all weeds. This poison is broad-based, non-selective, and lethal to plants, animals, soil life, bacteria and marine organisms.

Heedless of its danger, glyphosate is increasingly used by wildlife “managers” as if it were safe as aspirin.

We’ve known for some time that glyphosate (Roundup) has been linked to cancer, attention deficit disorder, and damage to microorganisms in the soil.

It’s also harmful to the digestive tracks of wildlife, livestock, pets and people – as well as having strong ties to the increasing presence of autism in children. Here is the latest research confirming the link to cancer.

Glyphosate Classified Carcinogenic by International Cancer Agency

The International Agency for Research on Cancer (IARC) released its finding on March 20, 2015 concluding that there is sufficient evidence of carcinogenicity based on laboratory studies. Here is a link to the Study Summary.

Glyphosate is touted as a “low toxicity” chemical and “safer” than other chemicals by EPA and industry and is widely used in food production and on lawns, gardens, parks, and children’s playing fields. However, IARC’s new classification of glyphosate as a Group 2A “probable” carcinogen finds that glyphosate is anything but safe. According to IARC, Group 2A means that the chemical is probably carcinogenic to humans based on sufficient evidence of carcinogenicity in experimental animals. The agency considered the findings from an EPA Scientific Advisory Panel report, along with several recent studies in making its conclusion. The agency also notes that glyphosate caused DNA and chromosomal damage in human cells. Further, epidemiologic studies have found that exposure to glyphosate is significantly associated with an increased risk of non-Hodgkin’s Lymphoma (NHL).

“With the cancer classification on top of the documented weed resistance to glyphosate and water contamination resulting from its use, continued reliance on glyphosate is irresponsible from a public health and environmental perspective,” said Jay Feldman, executive director of Beyond Pesticides. “We have effective sustainable organic management systems that do not utilize glyphosate and it’s time that EPA and USDA recognized its responsibility to move away from hazardous and unnecessary pesticides,” he continued.

Ironically, EPA in 1985 originally classified glyphosate as ‘possibly carcinogenic to humans’ based on tumors in laboratory animals, but changed its classification to evidence of non-carcinogenicity in human years later, most likely due to industry influence, allowing the chemical to be the most widely used pesticides in the U.S. USDA has contributed to its growth by deregulating crops, including the vast majority of corn and soybeans, that are genetically engineered to be tolerant to the chemical. In recent years, weeds have exhibited resistance to glyphosate and its efficacy has been called into question. Additionally, the U.S. Geological Survey (USGS) routinely finds glyphosate in U.S. waterways especially in the Midwestern states and the Mississippi River valley. Ecological data also reports that glyphosate and glyphosate formulated products are toxic to aquatic organisms, and is extremely lethal to amphibians.

But the U.S. regulatory agencies have ignored questions about its hazards and its necessity in crop production. Last year, cotton growers applied for an emergency exemption for the use of propazine on three million acres of cotton because glyphosate was no longer effective. Now that IARC has classified the world’s most widely used herbicide as a probable human carcinogen, EPA must quickly reevaluate its widespread use and registration status.

This discussion is mainly about what glyphosate does to people. But it is just as bad for plants, animals and soil life.

A factor in the mysterious decline of quail and pronghorn is intestinal infections and parasites. As with humans, animal health issues are probably symptoms of the damage glysophate does to micro-organic life. Because microorganisms control immune systems, they are as important to the health of animals and plants as they are to human health.

Here is a science-based discussion of what glyphosate does to all living organisms.

  • Thank you for sending out this email. For years I have worried about Round-Up ready GMO crops. They are terrible for pollinators and terrible for farmers who no longer are allowed to keep their seeds. Theirry Vrain’s video tells us about the effect Round Up is having on our health and the health of soil, plants and other animals. How can Monsanto be stopped from issuing reports about studies that show that Round Up is benign? Why can’t the EPA do more to reign in the chemical industry? Now we have a Congress that wants to weaken the EPA further. Over 84,000 chemical compounds are now registered with the Environmental Protection Agency, but “only a fraction have ever been fully tested for health effects on humans.” The Toxic Substances Control Act was passed almost 40 years ago, and no changes have been made to this legislation.

  • Dear Ruth,

    Many thanks for this comment.

    Although the Act remains on the books and so in theory remains the law, in practice it has been continuously eroded, as have most of our ordinances and practices intended to maintain food purity and environmental health.
