I wish there was more discussion about the impact of these herbicides on insect populations. For instance the Monarch butterfly population has dropped 90% due to herbicides such as Roundup. No public discussion.
Part of the reason there might not have been much public discussion is that the underlying story is not that Roundup directly affects butterflies, but, according to the study, it is simply very effective at eliminating weeds that the butterflies were relying on --- making this less a story about Monsanto and more about the impact of industrial-scale farming on local fauna.
