Humanity Has Killed 83% of All Wild Mammals and Half of All Plants: Study

Posted by collectivist

"When it comes to planet Earth, humans are very tiny.
The weight of all 7.6 billion humans makes up just 0.01% of all biomass on Earth, according to a report published in the Proceedings of the National Academy of Sciences on Monday.
Bacteria, by comparison, make up 13% of all biomass, plants account for 83%, and all other forms of life make up 5% of the total weight, according to the report.

Despite being such a small part of the planet, humans have been steadily destroying everything else for the past few millennia, the Guardian reports.
In fact, humans have caused the annihilation of 83% of all wild mammals and half of all plants, the authors of the report found.
And it’s not just that humans are wiping out wildlife — they’re also determining the animals and plants that remain.
Of the birds left in the world, 70% are poultry chickens and other farmed birds. And of the mammals left in the world, 60% are livestock, 36% are pigs, and a mere 4% are wild.

Marine mammals, meanwhile, have plunged by 80% over the past century, the report found.
“It is definitely striking, our disproportionate place on Earth,” Ron Milo, a professor at the Weizmann Institute of Science in Israel who led the report, told the Guardian. “When I do a puzzle with my daughters, there is usually an elephant next to a giraffe next to a rhino. But if I was trying to give them a more realistic sense of the world, it would be a cow next to a cow next to a cow and then a chicken.”
This staggering imbalance between domestic and wild animals is being driven by industrial farming, extraction of resources, and the expansion of human civilizations, all of which destroy ecosystems, according to the report."

That Uplifting Tweet You Just Shared? A Russian Troll Sent It

Here’s what Russia’s 2020 disinformation operations look like, according to two experts on social media and propaganda. By   DARREN LINVILL   &   PATRICK WARREN Internet trolls don’t troll. Not the professionals at least. Professional trolls don’t go on social media to antagonize liberals or belittle conservatives. They are not narrow minded, drunk or angry. They don’t lack basic English language skills. They certainly aren’t  “somebody sitting on their bed that weighs 400 pounds,”  as the president once put it. Your stereotypical trolls do exist on social media, but the amateurs aren’t a threat to Western democracy. Professional trolls, on the other hand, are the tip of the spear in the new digital, ideological battleground. To combat the threat they pose, we must first understand them — and take them seriously.

The Nightmare Scenario That Keeps Election Lawyers Up At Night -- And Could Hand Trump A Second Term

The Nightmare Scenario That Keeps Election Lawyers Up At Night -- And Could Hand Trump A Second Term   (Photo: Photos: Getty Images) Americans will almost certainly go to bed on Nov. 3 without knowing who won the presidential election. Since millions of people will vote by mail, constraints on time and resources will slow ballot counting into potentially a weeks-long process. Voting patterns suggest it’s likely that President  Donald Trump  could end Election Day in the lead in certain key states, only to be overtaken by Democratic opponent  Joe Biden  when more votes are tallied.  This could create a nightmare scenario during the three months stretching from Election Day to the Jan. 20 inauguration: a battle on the state and congressional level over who is the legitimate winner. This could include Congress reconvening on Jan. 6, presided over by Vice President  Mike Pence , with no consensus over its potential role in choosing the next president. This...

When Life Hands You Lemons

 It's like this folks: sometimes your mind goes blank. Happens more than usual with me of course. Take this forum for instance. I wanted to post something today and couldn't think of a topic. At least not a non-sexual one and we know sexual ones lately have been frowned upon.  Then along comes one of our regulars and complains about something. Well, they might not say it was a complaint, just an observation, but it was a complaint. A minor one. It has something to do about being able to make something out of nothing. Sort of like me this morning, how to make a thread out of an empty head? But they (notice I am using the correct pronoun, not saying he or she), by what they said got me thinking. What I thought was: Not sure if that is the actual saying, if I remember correctly, I remember the saying going something like this: Umm, no, I don't think the saying I am thinking of goes that way either, maybe ONE of you good folks can remind me how the saying goes. Either way, when...
