One of my horticulture teachers suggested that if anyone is to worry about cancer, that she's seen more people than she can count taken from melanoma over the years, in comparison to no one that she's known who's died, or even become sick from glyphosate exposure. Anecdotal, sure. That's not to say that the stuff is as safe as water however. For who knows what domino flow-on affects these chemicals will have on us, our future generations, and all other life on Earth. I mean, as the herbicides are used, the plants themselves adapt and evolve, which they wouldn't have done in such a manner otherwise.
