Haven't had an open thread in a while, but there's lots of random news worth sharing, including this scary bit about the decimation of Monarch butterflies.
Monarchs lay their eggs only on milkweed, and patches of the plant have rapidly disappeared from the Great Plains over the last decade. As corn prices have risen — spurred in part by a government mandate to add ethanol to gasoline — farmers have planted tens of millions of acres of idle land along the monarchs’ path that once provided both milkweed and nectar.
At the same time, growers have switched en masse to crops that are genetically engineered to tolerate herbicides. The increased use of herbicides has all but wiped out milkweed that once sprouted between rows of corn and soybean.
As a result, Dr. Taylor said, the monarchs must travel farther and use more energy to find places to lay their eggs. With their body fat depleted, the butterflies lay fewer eggs, or die before they have a chance to reproduce.
