That's two different things. The second point is very interesting.

First, Monsanto's own documents say there is no safe level of glyphosate. The mechanism of action is antibiotic and genotoxicity. It was patented as an antibiotic. Small amounts kill gut bacteria, for example. You're oversimplifying and underestimating the safety of any amount of glyphosate and NNG, a contaminate inherent to all glyphosate.

Second, no doubt the overall benefit to agribusiness is massive, but to humanity as a whole, who can say? What might have been developed if not this? Even with this, people are still starving to death and the planet is overheating. I agree everything requires a balance of risks and benefits. The allies would have lost WWII without asbestos. The manipulations of science and failures to follow the science because of "company product objectives" is inexcusable. No corporations should have such influence over science and medicine.
