Scientists Found Plastic Inside Human Brains -- And It's Getting Worse

[00:00:00]Scientists just found plastic inside human brains.

[00:00:04]Not traces.

[00:00:06]Not residue.

[00:00:08]Actual microplastic particles embedded in brain tissue.

[00:00:13]A 2024 study examined 52 human brains.

[00:00:18]Every single one contained microplastics.

[00:00:22]But here's the part that should terrify you. The brains of people who died in 2024 had 50% more plastic than brains from 2016.

[00:00:32]In just 8 years.

[00:00:34]These aren't pieces you can see.

[00:00:37]They're fragments smaller than a human cell, invisible, odorless, inescapable.

[00:00:43]They cross the blood-brain barrier, a wall your body spent millions of years evolving to protect its most vital organ.

[00:00:51]Researchers found the highest concentrations in the prefrontal cortex.

[00:00:56]The part of your brain that controls decision-making, personality, and what makes you human.

[00:01:02]We've been warned about microplastics in water, in food, in the air.

[00:01:09]But we assumed the brain was safe.

[00:01:12]It wasn't.

[00:01:14]The average person now ingests a credit card's worth of plastic every week.

[00:01:20]And nobody [music] knows what it's doing to us.
