CNN —Every winter, millions of monarch butterflies journey thousands of miles across North America to spend winters in the forests and mountains of central Mexico. The US Fish and Wildlife Service proposed listing the monarch butterfly as threatened with extinction under the Endangered Species Act. The butterfly’s eastern migratory population is estimated to have declined by roughly 80%, while the western migratory population plunged by more than 95% since the 1980s, according to US wildlife officials. Eduardo Rendón-Salinas, the lead of the monarch butterfly program for WWF-Mexico, previously told CNN that the climate crisis is a major contributing factor to the decline. Rendón-Salinas said what’s happening to monarch butterflies is representative of what pollinator species such as bees, birds and other butterflies face globally.
