As you probably know, we have done quite a number on this spectacular species, through deforestation in Mexico, reducing its food crops further north in the U.S., and poisoning its habitat everywhere; such blows make them even more susceptible to external pressures, like severe weather, in particular the drought in Texas (“external” if you don’t count our carbon-dirty hands in disrupting traditional weather patterns through global warming).
Here are some graphs of the shocking declines and here’s an interview with a biologist whose entire professional career has been about them disappearing. There’s nothing personal, of course, in this drive to extinguish one more species; we’ve done it to the whole planet, and even ourselves.
Can you do anything to keep this remarkable animal, which has a multi-generational, continent-spanning migration, around for your grandchildren? You can plant milkweed, stop the wide-spread poisoning of the environment through herbicides and pesticides, and drive less.. say what? The field-to-field cropping of corn to meet the ethanol demand means that “weedy” edges have been plowed under. We must all change our lives.
