Photo by @FransLanting As frail as they are, Monarch butterflies are powerful symbols for the vibrant connections between Mexico, the US and Canada. They spend their summers in the US where they reproduce, but they need Mexico’s mountains to overwinter and as global warming progresses, they will need Canada as an extension of their range. At a time when some think borders need walls to become barriers, Monarchs flutter back and forth at will and unite a continent. Monarchs cannot be claimed by a single country, but we all have a stake in their future. Unsustainable logging in Mexico’s mountains deprives Monarchs of critical habitat. The industrial use of pesticides in the US has dramatically reduced their numbers and that deprives people in Mexico—and everywhere else—of a natural wonder that has no equal on earth. Monarchs can only thrive when people unite to protect them. Check @FransLanting for more images of their astonishing gatherings in Mexico and see what happens when a snowstorm brings millions down to the ground. @ChristineEckstrom @thephotosociety @XercesSociety #Butterfly #Monarch #Endangered #CenterforBiodiv #Monarch_Watch #Migration
