Warn the president: Monarch's near Mexico City are about to invade America!

https://www.cbsnews.com/news/monarch-butterflies-are-at-risk-of-extinction-and-that-could-threaten-humans-too/

****snip****

Later this spring and summer, three generations of monarchs should blanket the entire United States east of the Rockies. Then in mid-August a special super-generation will fly all the way back to Mexico to these very same mountains. That means the butterflies they saw are the great-great-grandchildren of the butterflies that were there last winter.

Just a few years ago, Rendon worried he might be seeing the last generation because between 1994 and 2016, this eastern monarch population plunged more than 80 percent and a federal review found "a substantial probability" of collapse in the next two decades.

Monarch butterflies found in California overwintering sites has decreased by 89 percent from the last year, going from 148,000 to only 30,000 butterflies. This marks an overall a 96 percent drop from the 1980s, where 10 million monarchs made the trip annually. Scientists are debating as to whether the butterflies have passed the point of no return, and if there is anything that can be done to help.

I'm really bummed by this bit of bad news. I have fond memories of visiting a Monarch grove near my childhood home. The numbers started started dropping off through the sixties and seventies, and continues to dwindle for decades until the last few years when the population appeared to stabilize. We even started to seeing small upticks some years then....BAM...the population just collapsed.
