What's killing Mexico's Monarchs?
What's killing Mexico's Monarchs? Millions of Monarch butterflies are dying in two
sanctuaries in Mexico. Environmentalists are charging that loggers
have been spraying pesticides in the sanctuaries to kill the
butterflies. Witnesses have reported seeing a strange luster on the
wings of the butterflies and smelling gasoline in the area. Mexican
authorities are investigating whether the butterflies died of
natural causes or were deliberately killed. The sanctuaries are the
wintering grounds of large numbers of Monarchs that fly south from
eastern Canada, and were built with help from the Canadian
government. MARCH 9, 2001
