It was “supposed” to be harmless to humans and animals—the perfect weed killer. Now a groundbreaking article just published in the journal Entropy points to Monsanto’s Roundup herbicide, and more specifically its active ingredient glyphosate, as devastating—possibly “the most important factor in the development of multiple chronic diseases and conditions that have become prevalent in Westernized societies.”

That’s right. The herbicide sprayed on most of the world’s genetically engineered crops—and which gets soaked into the food portion—is now linked to “autism … gastrointestinal issues such as inflammatory bowel disease, chronic diarrhea, colitis and Crohn’s disease, obesity, cardiovascular disease, depression, cancer, cachexia, Alzheimer’s disease, Parkinson’s disease, multiple sclerosis, and ALS, among others.”
