They Chose Our Neighborhoods: Environmental Racism, Pollution, and the Communities Bearing the Cost

PUBLIC HEALTH

The Maps Came First: How Environmental Racism Was Zoned

In the 1930s, federal surveyors drew colored lines around American neighborhoods to tell lenders where money was safe. Green for the desirable. Red for the ones where Black families lived. The maps were retired decades ago. The air above them was not. This is the mechanism environmental racism and pollution actually run on: not malice in the moment, but a decision made once and then honored by every institution that came after.

A 2022 study in Environmental Science & Technology Letters mapped present-day pollution against those original grades across 202 U.S. cities. Neighborhoods that had been graded D — redlined — carried nitrogen dioxide levels more than 50% higher than the neighborhoods graded A. The researchers were careful about what this means: redlining and air pollution are linked not because a line on a map poisons anyone, but because that line determined where highways were routed, where industrial zoning was permitted, and whose objections a planning board had to take seriously.

And the disparity did not stop at the map’s edge. Within every single grade — including the green ones — racial gaps in exposure persisted. Redlining was one instrument among many. The song it was playing was older.

It Is Not Income. It Is Race.

The most common deflection in this conversation is that poverty, not race, explains the pattern — that poor people live near industry, and Black Americans are disproportionately poor, and so the disparity is economic rather than racial. It is a tidy argument, and it would let everyone off the hook, because a market has no author. The data does not support it. Environmental racism and pollution do not sort themselves by wallet.

Researchers examined more than 5,000 emission source types across the United States and found that people of color face above-average exposure from sources responsible for roughly 75% of total fine-particulate pollution, while white Americans face below-average exposure from sources responsible for about 60%. Nearly every major category — industry, construction, agriculture, light and heavy vehicles — showed the same tilt. The lead author put it plainly: the racial disparities hold at every income level. A Black family earning a comfortable income still breathes worse air than a white family earning the same.

That is the finding that closes the escape hatch. If the burden tracked income alone, we would be talking about class. It tracks race independently of income, which means we are talking about something that was decided about Black people specifically — and is still being decided. The communities living at the fence line of a chemical plant are not there because of a market. They are there because of a choice.

What It Costs, Measured in Children

Abstractions are easy to argue with. Children are not. Between 2012 and 2020, Black children in the United States were hospitalized for asthma at rates roughly four to five times higher than white children — at the widest, 36.7 per 10,000 against 9.4. Hospitalization rates fell for both groups over the decade. The gap between them did not close.

Along the eighty-five-mile stretch of the Mississippi between Baton Rouge and New Orleans — roughly a quarter of the entire American petrochemical industry, packed against communities that are majority Black — Johns Hopkins researchers found chloroprene to be the single largest contributor to cancer risk in two census tracts of St. John the Baptist Parish. Residents there live behind chain-link fence from the plants. They have been asking for monitoring, for buyouts, for the plants to meet their own permits, for decades.

These are the numbers behind the phrase sacrifice zones — and it is worth saying clearly that nobody in them volunteered. The sacrifice was assigned. The health consequences of this exposure do not stop with the generation that breathes it, either; they are written into the body and carried forward, which is the ground covered in the epigenetic inheritance of toxic exposure across five centuries.

The Same Logic, Crossing an Ocean

Ogoniland sits in the Niger Delta. In 2011, after fourteen months of fieldwork — over 200 locations, more than 4,000 samples, 142 groundwater wells — the United Nations Environment Programme published what it found. At Nisisioken Ogale, families were drinking water containing benzene at levels more than 900 times the World Health Organization guideline. An eight-centimetre layer of refined oil floated on the groundwater feeding community wells. Hydrocarbons had reached five meters into the soil at 49 sites. UNEP estimated the cleanup at 25 to 30 years and called for a one-billion-dollar restoration fund as a starting point.

The distance between St. John the Baptist Parish and Ogoniland is about six thousand miles. Environmental racism and pollution do not respect that distance, because the logic is the same one. Extraction is sited where the people affected have the least power to refuse it, and the profit travels somewhere else. Ken Saro-Wiwa was executed in 1995 for organizing the Ogoni against exactly this. What he was defending was not a grievance about cleanliness. It was a relationship between a people and their land that no company had the right to end.

And the logic keeps finding new industries to wear. The water-hungry, power-hungry infrastructure of the AI boom is being sited by the same calculus — a pattern traced in how data centers are repeating environmental racism. The technology changes. The question of who bears the cost of pollution does not.

Warren County, and What Communities Did Next

In 1978, a trucking company drove North Carolina’s back roads at night, opening a valve and letting PCB-laced liquid run out along some 240 miles of roadside across fourteen counties. The state had to put the contaminated soil somewhere. It chose Warren County — the county with the highest proportion of Black residents in North Carolina, and among its poorest.

In September 1982, residents lay down in the road in front of the trucks. Roughly 500 people were arrested. They did not stop the landfill. What they did instead was give the country a name for what had been happening to it, and the EPA later called those protests the watershed event that produced the environmental justice movement. Every federal environmental justice office that exists traces back to people in a rural county deciding that being chosen was not the same as consenting.

What Our People Have Always Known About Land

There is a reason this particular harm cuts as deep as it does. In African and Afro-diasporic traditions, land is not inventory. It is kin. It holds the buried, it holds the shrine, it holds the knowledge of which plant grows where and what it is for. To poison a people’s water is not only to injure their bodies. It is to sever a relationship that carried their memory.

Ubuntu — I am because we are — asks a question that permit hearings are structured to avoid: good for whom? Not good on balance, not good for the tax base, not good for the region. Good for whom, specifically, and at whose expense. A framework that begins there cannot treat a fence-line community as an acceptable rounding error, because there is no such thing as a body whose harm does not travel through the whole. It is the same insistence that runs through Black feminist public health and its work toward liberation, which refuses to measure any one of our bodies apart from the whole.

This is also why the grief that accompanies environmental harm is not a side effect to be managed with counseling while the plant keeps running — a distinction drawn out in environmental grief as a community health condition. Fenceline communities health outcomes and fenceline community mourning are the same wound, measured in different instruments.

Where the Leverage Actually Is

Siting decisions are made in rooms that are legally open and practically empty. Zoning boards, permit hearings, environmental review comment periods — these are the moments when a facility is stoppable, and they pass quietly. Communities that track them early, that arrive with their own air monitoring data, and that arrive together have stopped projects that looked inevitable. Knowing the calendar is a form of power.

Community-held data matters as much as community presence. When residents gather their own measurements, they stop being people with complaints and become people with evidence — and the burden of explanation shifts across the table. The same is true of remedy: cleanup timelines, monitoring, and buyouts that are defined by the people living there hold up far better than programs designed for them elsewhere.

Environmental racism and pollution were built through decisions. That is the hard truth in this, and it is also the hopeful one. What was decided can be decided differently — but only by communities with the standing, the data, and the collective weight to make refusal cost something.

If you grew up near the plant, the highway, the transfer station — and were told your whole life it was just where you lived — send this to someone who grew up there with you. It was never just where you lived.
