Meanwhile…

Like Nero fiddling while Rome burned, most of America is transfixed and distracted by the daily Gong Show in Washington.

It’s bad enough that–while the news focuses on the President’s most recent bizarre and misspelled tweet storm– cabinet members are busily rolling back regulations protecting citizens from contaminated air and water, protecting students from predatory “educators,” or protecting irreplaceable national lands from being ravaged and looted by fossil fuel interests.

Worse, we are also being distracted from emerging reports about changes to our planet that should terrify us.

The world’s insects are hurtling down the path to extinction, threatening a “catastrophic collapse of nature’s ecosystems”, according to the first global scientific review.

More than 40% of insect species are declining and a third are endangered, the analysis found. The rate of extinction is eight times faster than that of mammals, birds and reptiles. The total mass of insects is falling by a precipitous 2.5% a year, according to the best data available, suggesting they could vanish within a century.

The planet is at the start of a sixth mass extinctionin its history, with huge losses already reported in larger animalsthat are easier to study. But insects are by far the most varied and abundant animals, outweighing humanity by 17 times. They are “essential” for the proper functioning of all ecosystems, the researchers say, as food for other creatures, pollinators and recyclers of nutrients.

We are beginning to see reports of the collapse of insect populations, and the researchers who authored the report say that the phenomenon extends globally–far beyond the specific collapses that have been documented. As the article in the Guardian put it,

The researchers set out their conclusions in unusually forceful terms for a peer-reviewed scientific paper: “The [insect] trends confirm that the sixth major extinction event is profoundly impacting [on] life forms on our planet.

“Unless we change our ways of producing food, insects as a whole will go down the path of extinction in a few decades,” they write. “The repercussions this will have for the planet’s ecosystems are catastrophic to say the least.”

The article, published in the academic journal Biological Conservation, attributes the dramatic decline of insect populations to intensive agriculture, especially the heavy use of pesticides, although it also found that urbanization and climate change are significant contributors to the problem.

There have been a number of stories about the mysterious loss of bee colonies-indications are that western states like Oklahoma lost half of their bumblebees between 1949 and 2013. But the problem extends far beyond bees, and the consequences of the predicted insect loss would be staggering.

One of the biggest impacts of insect loss is on the many birds, reptiles, amphibians and fish that eat insects. “If this food source is taken away, all these animals starve to death,” he said. Such cascading effects have already been seen in Puerto Rico, where a recent study revealed a 98% fall in ground insects over 35 years.

The new analysis selected the 73 best studies done to date to assess the insect decline. Butterflies and moths are among the worst hit. For example, the number of widespread butterfly species fell by 58% on farmed landin England between 2000 and 2009. The UK has suffered the biggest recorded insect falls overall, though that is probably a result of being more intensely studied than most places.

I strongly advise clicking through and reading the entire, depressing article. At the very least, it will give you something to be depressed about other than the disaster in the White House.
