Count finds a sharp drop in monkeys' butterflies in California


SAN FRANCISCO (AP) – A group of environmental scientists have labeled the number of western monarch butterflies migrating from California to the coast as "disturbing".

A recent account of Xerces Society registered with less than 30,000 butterflies, falling from 2017 to 86.

In 1981, in 1981, in 1981, more than 1 million western monarchs were counted in California, the San Francisco Chronicle reported.

The Company Xerces makes annual Thanksgiving and New Year counting, and there is no impact on the numbers. He said that there is no delayed migration and butterflies are not reported in other countries.

A 2017 study conducted by researchers at Washington State University found that species will disappear in the next decades to save anything.

Scientists say butterflies threaten pesticides, herbicides and devastation on the migratory route. They also have an impact on climate change.

University of Michigan and Stanford University researchers found carbon dioxide in the car and factory spills, natural toxin, dairy herds, to feed caterpillars against parasites.

Western monarch butterflies are usually from November to March, along the California coast.
