Glyphosate and GMOs Are Damaging Our Health. It’s Time to Ban Them

The Scientific Evidence That Justifies Banning GMOs and Glyphosate
There are an enormous number of published scientific studies showing that GMOs and their associated pesticides are responsible for multiple serious health problems for people, animals, and the wider environment.
The widespread adoption of GMO crops in the U.S. has resulted in a massive increase in the application of glyphosate, the active ingredient in Roundup, as the primary method of weed control. [1]
A landmark study on glyphosate by Panzacchi et al. was published on June 10, 2025, examining total lifetime exposure to the so-called ‘safe’ levels to which most people are subjected [2].
The study found that the lowest dose of 0.5 mg/kg, which is four times lower than the US Environmental Protection Agency’s (EPA) proposed ‘safe’ level, led to increased rates of both benign and malignant tumors at various anatomical sites compared to the controls. These tumors included leukemia, skin, liver, thyroid, nervous system, ovary, mammary gland, adrenal glands, kidney, urinary bladder, bone, endocrine system, pancreas, uterus, and spleen. [2,3]
This study confirms evidence from earlier research, including that by the IARC and Seralini et al., among many others[4,5]. It also validates the accuracy of “Genetically engineered crops, glyphosate and the deterioration of health in the United States of America,” where Dr. Nancy Swanson, our co-authors, and I demonstrated how glyphosate and GMOs are linked to over 20 chronic diseases in the U.S [1].
The First Credible Peer-reviewed Lifetime Study of GMOs and Roundup
Until Panzacchi et al. was published, there was only one credible, independent, non- industry funded, peer-reviewed lifetime feeding study of GMOs and Roundup. It found that mammary and other tumors, liver and kidney damage result from regular exposure to minute amounts of Roundup and/or a diet containing GMO corn, similar to the typical exposures people get from food.
