Right now, the Trump Administration is pushing hard to drill for oil and gas in places that were previously off-limits. One of those places is the Arctic National Wildlife Refuge, and in June, the administration took another step forward in the process of opening this enormous protected area for drilling. Season 3 of Threshold is actually all about this controversy: it’s called The Refuge, and…
We’ve been telling the story of the petrochemical industry in Louisiana, but this isn’t just a Louisiana issue, or even just an American one - petrochemicals are a global industry with a global impact. In this episode, we think about our collective future, and how we might begin to navigate living with all this plastic. Threshold is nonprofit, listener-supported, and independently produced. You…
For decades, the residents of St. John the Baptist Parish breathed in toxic chemicals from a massive complex that makes neoprene - a synthetic rubber. But while residents suspected something was wrong, they were still shocked when the EPA told them they had the highest risk of cancer in the nation. Why were they just now being warned? And what was the government going to do about it? In this…
People have objected to the toxic side effects of industry in Louisiana and across the country for a long time. A swell of activism in the 70s and 80s connected civil rights with environmental issues and public health, so that by the 1990s, it seemed like the nation was entering an environmental justice renaissance. And yet, low income and minority communities have remained at risk. In this…
We know that many of the chemicals being released by plants in the corridor can cause cancer. We also know that the cancer risk along this stretch of the Mississippi is unusually high. But how do we know for sure that these things are connected? In this episode, we explore what we know about pollution and disease. Threshold is nonprofit, listener-supported, and independently produced. You can…
At the beginning of the 20th century, the corridor began a transition from one deadly industry to another—from sugar to petrochemicals. This transition wasn’t a coincidence. The history of industry intersects with the history of race in Louisiana all the way up to the present day. In this episode, we look at how and why petrochemicals came to the corridor. Threshold is nonprofit,…
Before gas, oil, and benzene, there was sugar. This is the story of the first industry that exploited people in the Corridor, an industry that brought the ancestors of today’s residents to the area and laid the foundations for the modern petrochemical industry.

One of the largest concentrations of petrochemical plants in the country lies along the Mississippi River between Baton Rouge and New Orleans. Petrochemicals are made from fossil fuels. We use them to make a huge range of synthetic materials that are found in almost every part of our daily lives — but petrochemicals are made where people live. Here, amidst houses, schools, and churches, more than…
Coming Tuesday, June 2nd: A podcast about history, pollution, and resistance on the frontlines of America’s petrochemical industry. Over seven episodes, The Corridor examines how Louisiana became a center of industry and an epicenter of disease, with some communities facing cancer risks among the highest in the nation. Everything that’s happening in the industrial corridor today has been shaped by…
Like many countries, Iran has struggled with major water scarcity in recent years. Last summer its capital, Tehran, came very close to “day zero,” the day when the whole city runs out of drinking water. Now, with the United States at war with Iran, President Donald Trump has further threatened the country’s civilian water infrastructure, including dams, water treatment plants, and the electrical…
