'High Levels' Of Microplastics Found In Human Brains

Researchers from the University of New Mexico Health Sciences Center found 'alarmingly high levels' of microplastics in human brains. The amount appears to be a higher concentration of plastic than found in other organs, and scientists say the accumulation is growing over time. So, how did plastic get there in the first place? And what, if anything, should people do about this issue? Dr. Marcus Garcia joins Chris and Gabby to explain the methods used in the study, what researchers learned, and the questions they're still working to answer. He also shares what scientists believe to be the catalyst for plastic entering our food chain.
