Monarch Butterflies are a remarkable species. Both the California populations and the Eastern populations are at severe risk, even of possible extinction in the not too distant future. In the East, Monarchs migrate from overwintering all together on a few acres in Mexico, to travel by successive generations as far north as Canada. The last generation in fall flies all the way back to overwinter in Mexico.

Yet climate change-related drought, herbicides and pesticides, and destruction of the milkweed that require, along with illegal logging of their winter grounds, imperils their very existence. The iconic butterfly that children study may vanish.
