Earth Talk: Monarch butterflies in sharp decline

Roddy Scheer

The monarch butterfly, royally adorned in black, white and reddish-orange and able to migrate as far as 2,800 miles, is a true wonder of nature. Each year monarchs travel from Canada and the U.S. to hibernate in the forests of central Mexico. But in recent years the monarchs have been in sharp population decline due to habitat loss, eradication of the plants it depends upon and other environmental factors.
