The Invisible Killer: Gaia’s Plastic Test

from Matter of Fact: A play on "matter" (physics) and "facts" (news). · host Larry White

Microplastics have permeated virtually every environment on Earth, from the depths of the Mariana Trench to the food we eat, originating from the breakdown of larger waste and everyday items like microwaved plastic containers. Research confirms that these tiny particles are entering the human body through ingestion and inhalation, having been detected in organs such as the lungs, blood, and heart. While the full extent of their toxicity is still being studied, estimates suggest humans ingest approximately a credit card's weight in plastic every week, marking this as a significant ecological and potential health crisis.
