Environmental Threats to the Monarch Butterfly
the South from deforestation
reports on the threat to one of the great wonders of the natural
world, the Monarch butterfly. The species is in serious threat of
extinction due to deforestation. Every year, tens of millions of
monarch butterflies migrate from the United States and Canada to
spend the winter on a few remote forest mountains in central Mexico
where they huddle together for warmth on the branches of the oyumel
trees. In spring they leave, dispersing across North America where
they spend the warm summer months before heading south again as
the weather turns cold. The round trip is 14,000 kilometres (8,700
miles) and an incredible five generations. The parents pass on genetic
maps so the young can navigate their way back to the Mexican oyumel
forests. Mexican authorities only have a single generation to stop
illegal logging from decimating the few remaining islands of oyumel
forest and therefore destroying the Monarch's over-wintering habitats

New and additional
threats faces the monarch butterfly during their migration to North
America. Pollen from gene altered corn appears to be killing the
butterflies. Milkweed grows in abundance amongst and around the
corn. Pollen from the corn lands on the Milkweed, which is a favorite
food of the Monarch. One in five monarch larvae are known to be
dying after being exposed to the toxic corn pollen.
