Our Plastics are Hunting Us Again--They're Now Invading Our Dear Fishes' Brains!

I just can't stress enough how fvcked we are.

Well, let me go straight to the point: the tiny plastic particles called “nanoplastics” may have been building up in fish brains, altering their behaviors.

"Our study is the first to show that nanosized plastic particles can accumulate in fish brains," said study author Tommy Cedervall, from Lund University in Sweden, in a statement.

But how did this happen?

Well, such particles spread through the marine life by being eaten by plankton first (not cool, Sheldon J.). Such are then consumed by fish just as how the good 'ol food chain goes. That's when these minuscule particles cross the blood-brain barrier and make their way to the brain. And their effect to these little fellas is disturbing. They disrupt fishes' survival by making them explore their surroundings less and slowing down their eating.

Researchers even found how size matters when it comes to plastic particles as smaller nanoplastics managed to kill plankton while the larger ones didn't. "It is important to study how plastics affect ecosystems and that nanoplastic particles likely have a more dangerous impact on aquatic ecosystems than larger pieces of plastics," said Cedervall.

And more importantly, what happens to humans, then? Will the nanoplastics travel to our bloodstreams/tissues the same way? Are we doomed to killing ourselves slowly?

Sounds like a literal taste of our own medicine, isn't it?
