Humans are contaminating the environment, spraying insecticides without regard to their toxicity because they weren't taught science and killing species that they incorrectly believe are unimportant.
Yup! Let's keep indiscriminately spraying insecticides and wonder about the consequences.
A well-educated friend used 'ant poison' that his dog licked up and was surprised his well loved dog was poisoned.
I watched as a well-educated person sprinkled Diazinon with his BARE HANDS. [Diazinon is an acetylcholinesterase inhibitor, clearly revealed on the label.] Your lack of intellectual curiosity and poor science education doesn't matter until your heart stops working.
Butterfly decline signals trouble in environment
Although the insect looks fragile, like most bugs it clings to existence more ferociously than mammals. If butterflies are going extinct, “it’s a strong indicator that we’re messing up the environment around us,” Robbins said.
Numerous animals such as Carolina parakeets and passenger pigeons have vanished, but butterflies have been known to disappear in one place and show up in another, which is why the Fish and Wildlife Service waited at least a decade to announce the extinction of the skippers.
Eighty percent of food crops are pollinated by insects such as bees, moths and butterflies, according to scientists. Nearly a third of the nation’s honeybees have disappeared, and scientists theorize that pesticide use is a contributing factor in their decline.
