Believe someone here was defending glycophosphates aka Roundup™ (..something like, "Oh that's been exaggerated.. cha.")
Per FOE (Friends of the Earth) recently:

Monarch butterflies are in trouble. They’ve declined by 90% in the last 20 years. And a key culprit is the massive increase in the use of glyphosate -- a.k.a. Monsanto’s Roundup®.

It’s a simple formula: More Roundup® = less milkweed = fewer monarchs.

At Friends of the Earth, we’re working to get this toxic pesticide out of our food system and shift to organic agriculture --

Sure is difficult proving-those-negatives whilst eliding side-effects when a substance is "used as intended".
Interconnectedness.. Don't fuck with a planet with megatons of new $wares$ ..without Checking-In every decade or so?
Which is I suppose, another major, recurrent reason we've gotten where we are Today. (Especially when trusting a mega-bizness like Monsanto, right behind the Tobacco folk in voire dire.)

So it (continues to) --> Go because Good-is-stupid.
