DuPont is one of the longest-operating companies in the United States. They are also one of the most dangerous. For decades, maybe even longer, the company has been dumping poisonous toxins into the environment, and these toxins then make their way into the bodies of humans and animals, causing life-threatening conditions that may never go away. And when they phase out one toxic chemical, they replace it with something just as deadly, and that’s exactly what’s happening right now with the company.
