If you've ever wondered why so many people seem so nutty, there's a pretty simple explanation: our brains rewire as they're continually bombarded with media and government pronouncements of doom and gloom. This noise firms up connections in the brain centers that receive and sort input in order to determine whether or not a threat exists; the primary function of the brain, after all, is to keep its bearer alive. With connections constantly exposed to the noise thrown at us, they strengthen.
Entire industries rely upon this: "We're all gonna die because of Man-made Global Warming/Cooling/Change and it's All Your Fault!" "Black Lives Matter! (yours doesn't, if your skin's the wrong color)". "Save the penguins!" "Shave The Polar Bears!" "Fossil fuels!" "Donald Trump!" "Gun violence!"
All designed to scare the crap out of people because that's how they make money and retain control.
The newest thing comes from the "World Wildlife Fund", an organization that makes its money by making dire presentations in order to garner donations from the gullible. They're claiming that two-thirds of all wildlife on the planet - from insects to marine life to birds and reptiles and mammals - will be gone in the next four years! Auugh! Run around in circles, waving your hands, and don't forget to open your wallet because this is going to be All Your Fault. But if you send money, some of the damage might be remediated. Or not.
Never mind that "new species" are being "discovered" almost weekly, and never mind the fact that we don't know nearly as much about our planet as we like to think we do.
There's fear and anxiety to be spread, and money to be made in so doing.
