Insecticide Can Cut Bee Sperm by Nearly 40 Percent, Study Finds
nytimes, By JONAH ENGEL BROMWICH, JULY 28, 2016

A new study of male honeybees shows that two insecticides, banned in some European nations but still used in the United States, can significantly reduce the bees’ ability to reproduce.

The study, published in Proceedings of the Royal Society B, the leading biological research journal of the Royal Society, found that thiamethoxam and clothianidin, two chemicals from the neonicotinoid family of insecticides, reduce living sperm in male honeybees, called drones, by almost 40 percent.

“We’ve been able to show for the first time that neonicotinoid pesticides are capable of having an effect on the male reproductive system,” said Lars Straub, a doctoral student at the University of Bern in Switzerland and the lead author of the study. The effects of pesticides on honeybee populations are considered one culprit among several factors causing periodic declines.

The two neonicotinoids used in the study were banned in the European Union in 2013, but are used on an industrial scale in the United States.

The EPA needs to stop dragging its feet and ban these harmful practices and pesticides yesterday, already.

Like all species, nurture of the young is a driving force so 40% less baby bees is not good for the planet
or our food supply. They eed to protect humans as much as they protect the grey spotted jumping mouse.

In the head?? :VeryScared: That's gotta hurt.

Fireflies are struggling also.

Light pollution, a well-known disruptor for many nocturnal animals, poses a singular threat for fireflies. Because their courtship rituals rely on detecting luminous signals, fireflies are especially sensitive to background illumination.

. . . commercial harvesting from wild firefly populations. Most people are surprised to learn that, for decades, U.S. fireflies were harvested en masse to extract their light-producing chemicals, and that this practice is still going on.

Monarchs in western U.S. risk extinction, scientists say
by Laura Zuckerman, Reuters, September 7, 2017

(Reuters) - Monarch butterflies west of the Rocky Mountains are teetering on the edge of extinction, with the number wintering in California down more than 90 percent from the 1980s, researchers said in a study published on Thursday.

While much is known about the black-and-orange winged insects’ decades long population decline in the eastern United States, scientists have been unable to track the western variety accurately until the recent development of new statistical models.

Monarchs, which depend on a diminishing supply of milkweed plants for reproduction and food, are arguably the most popular of North America’s butterflies and have a huge international following among students and scientists. However, the western population has fallen to about 300,000 from 10 million less than four decades ago.

“If the population continues to decline at that rate, we will lose migratory monarchs in the western United States over the next several decades,” Washington State University biologist Cheryl Schultz, the study’s lead author, said in a telephone interview.

The migratory monarchs of the western United States have a 63 percent chance of extinction in 20 years and an 84 percent chance in 50 years if current trends continue, according to the study.

Because we truly are a nation of dangerous life-hating psychopaths, nothing sufficient will be done even though it was well within our means to live sustainably. You see, we "ain't care" about the world. This is a part of why we will be correctly remembered by history as a lost and wicked people.

What's that Einstein quote? The third world war will be fought with weapons and the forth with sticks and stones?
Except those future generations won't have bees shipped in trucks around the country to pollinate and Monsanto has
made sure their seeds can't be saved for next years planting. Sad.
