This is true, but it's significantly less direct than the news stories have indicated. The issue is that Roundup is being used to eliminate milkweed, which are essential for monarch butterflies. It's not Roundup or Roundup Ready crops that are harming monarch butterflies, but what they're being used to eliminate.
- sophacles 12y agoRight, it's like when you don't give a person food. You aren't harming him - his own body is doing that as a secondary effect of simple food denial. These distinctions are important.
- ambler0 12y agoI'm all for correcting oversimplified news stories, but I don't understand why you call this "significantly less direct". As far as I can see, it's exactly one step less direct, i.e. as close as you can get without killing them directly. As you say, milkweed is essential for them. It's literally the only plant this species lays its eggs upon.
- daeken 12y agoIt's significantly less direct because Roundup has no effect on the Monarch butterflies. The issue is the way it's being used by farmers. If it were not being used to eliminate milkweed, there would be no effect whatsoever on the butterfly populations. We would have the same problem with absolutely any other herbicide.

- daeken 12y agoI wonder what kind of scale you would need to make this work? I'd be curious to see numbers on it, and whether or not it's feasible; definitely a great option if so!
- ambler0 12y agoIn any case, it doesn't hurt to try and grow some milkweed in one's own yard, which many of us in my area do.
