How One Company Secretly Poisoned The Planet

Veritasium

Summary

Este vídeo investiga la historia y el impacto ambiental de los PFAS, conocidos como 'productos químicos eternos'. Comienza con el descubrimiento accidental del Teflón por DuPont en 1936, una sustancia revolucionaria por su resistencia, pero cuya fabricación requería PFOA (C8), un químico tóxico, persistente y bioacumulativo. A través de la historia de una demanda judicial en West Virginia, el vídeo detalla cómo DuPont y otras compañías ocultaron durante décadas la contaminación del agua y los riesgos para la salud humana (como cáncer y enfermedades tiroideas). A pesar de las regulaciones recientes, el problema persiste debido a que las empresas reemplazan un químico peligroso por otro similar, y estos compuestos están presentes en todo el mundo, desde envases de comida hasta nuestra propia sangre.

Transcript excerpt

In 1929 in Chicago, people kept mysteriously dying inside their homes. It took 15 deaths for the authorities to realize that these people were getting killed by their fridges. Because fridges back then were no longer just boxes of ice. Instead, they relied on a chemical looping through the back to stay cold. And the best chemical for this job was methyl chloride, a toxic and virtually odorless gas. So, if it somehow leaked from the fridge, it could kill you without warning. Other fridges used flammable gases instead, so a leak combined with a spark from the stove and your house could suddenly go up in flames. So, one company tried to solve this problem. But in the process, they accidentally created a seemingly magical substance. Soon, it made its way into a huge range of products, which were so popular they ended up in nearly every home in America. But what people didn't know was that th…
