Tell the Mexican Government to Reject Mining in the Monarch Butterfly Biosphere Reserve
Mexico's largest mining company is attempting to use a legal loophole to secure one of the final permits it needs to begin potentially catastrophic copper, zinc, and lead ore mining in the protected Monarch Butterfly Biosphere Reserve. This UNESCO World Heritage site contains overwintering habitat for most of the Eastern population of the monarch butterfly. Loss of habitat and destruction of milkweed, a plant required for the survival of monarchs, has led to a nearly two-thirds decline in the overwintering population in just 12 years. The Eastern population of North America's monarchs migrates every year to mountainous oyamel fir forests in Mexico, where the butterfliesroost from October to late March before returning to the U.S. and southern Canada. This is unique, as the monarch is the only butterfly known to make a two-way migration.
