Monarch Butterflies: A Tiny Global Traveler Fights for Survival

Monarch creatures may be small creatures, but they go on an epic adventure every year across much of the globe. Now, the federal government is stepping in. In December, the Fish and Wildlife Service proposed to list monarch butterflies as "threatened" under the Endangered Species Act. But since then, the new Trump administration has begun discussing rescinding the definition of "harm" in the act. That could remove certain protections for all listed species and their habitats.
