Advertisement The past few weeks I have been researching landscape designs to build a native plant butterfly garden. In my process of educating myself I found, to my surprise, that the monarch butterfly populations are crashing. There's been much speculation and debate by many as to why this is happening, be it GMO crops, pesticides and even milkweed being 'not as common' as it used to be etc. I just read this article and it seems like a valid hypothesis. https://www.msn.com/en-us/news/tech...te-road-salt-as-culprit-—-and-cure/ar-AAGKrx2. What are ya'lls thoughts on this topic?
