In AP Human Geography, environmental injustice is the disproportionate exposure of low-income and minority communities to environmental hazards (like landfills, factories, and polluted air or water) caused by discriminatory land-use, zoning, and investment decisions within cities.
Environmental injustice happens when the costs of pollution land unevenly across a city. Hazardous waste facilities, highways, incinerators, and industrial zones get placed near low-income and minority neighborhoods, while wealthier areas keep their parks, clean air, and tree-lined streets. The pattern isn't random. It grows out of decades of discriminatory land-use decisions, like zoning industrial uses next to redlined neighborhoods, because those communities historically had the least political power to push back.
In the CED, environmental injustice shows up in EK SPS-6.A.1 as one of the economic and social challenges created as urban populations move within a city. It sits alongside redlining, blockbusting, housing affordability, and disamenity zones. That grouping is the key insight. Environmental injustice is the environmental face of the same segregation and disinvestment patterns that produced unequal housing. Where a city draws its lines about who lives where also decides who breathes the dirty air.
Environmental injustice lives in Unit 6 (Cities and Urban Land-Use Patterns and Processes), Topic 6.10: Challenges of Urban Changes, and supports learning objective 6.10.A, which asks you to explain causes and effects of geographic change within urban areas. It's named directly in EK SPS-6.A.1 as one of the challenges resulting from intra-urban movement, so it's fair game on both multiple choice and FRQs. It also matters because it ties spatial patterns to power. If you can explain why hazards cluster in certain neighborhoods (discriminatory zoning, disinvestment, low land values from redlining), you're doing exactly the cause-and-effect reasoning 6.10.A demands. Responses like inclusionary zoning and local food movements (EK SPS-6.A.3) are the policy flip side, so know the problem and the fixes together.

De Facto Segregation (Unit 6)
Environmental injustice usually maps almost perfectly onto segregated residential patterns. When redlining and de facto segregation sort people by race and income into specific neighborhoods, hazardous land uses get steered toward those same neighborhoods. Same map, different layer.
Environmental Degradation (Units 5 and 7)
Degradation is the harm itself (polluted water, damaged land); injustice is about who lives next to that harm. Industrial pollution from Unit 7 and agricultural runoff from Unit 5 become environmental injustice the moment their burdens fall unevenly on poor and minority communities.
Gentrification (Unit 6)
Here's the twist worth knowing. When a polluted neighborhood finally gets cleaned up, rising property values can price out the very residents who endured the pollution. Some geographers call this 'green gentrification,' and it shows how fixing one urban challenge can trigger another.
Inclusionary Zoning (Unit 6)
The CED pairs urban challenges with responses, and inclusionary zoning is the response side of 6.10. Zoning created environmental injustice by concentrating hazards near certain residents, so reformed zoning is one of the main tools cities use to undo it.
Multiple-choice questions typically give you a scenario and ask you to name the pattern. A classic stem describes a city placing a hazardous waste facility in a low-income minority neighborhood while keeping industry away from wealthy areas, and the answer is environmental injustice. You may also be asked which factors cause it (discriminatory zoning, redlining-driven disinvestment, weak political power in affected neighborhoods). On FRQs, the term supports questions about urban challenges and quality of life. The 2022 SAQ on urbanization indicators, for example, used data on urban populations' access to safe drinking water, exactly the kind of unequal-access evidence an environmental injustice argument runs on. The move the exam rewards is connecting a spatial pattern (where hazards are) to a process (who decided to put them there and why).
Environmental degradation is damage to the environment itself, like deforestation, polluted rivers, or soil erosion, and it can happen anywhere. Environmental injustice is about distribution. It asks who is forced to live with that damage. A polluted river is degradation; routing every polluting facility toward the poorest neighborhoods in the city is injustice. On the exam, if the question emphasizes which group of people bears the burden, the answer is injustice, not degradation.
Environmental injustice means low-income and minority communities face disproportionate exposure to pollution and hazards while having less access to environmental amenities like parks and clean air.
It appears in EK SPS-6.A.1 under Topic 6.10 as one of the economic and social challenges created by population movement within cities, alongside redlining, blockbusting, and disamenity zones.
The cause is discriminatory land-use and investment patterns, since hazardous facilities get zoned near neighborhoods with low land values and little political power.
Environmental injustice is about who bears environmental harm, while environmental degradation is the harm itself, so always check whether the question focuses on people or on the environment.
Responses in the CED include inclusionary zoning and local food movements, which try to redistribute housing access and environmental amenities more fairly.
Cleaning up a polluted neighborhood can trigger green gentrification, displacing the residents who lived through the pollution, which links environmental injustice directly to housing affordability.
It's the disproportionate exposure of low-income and minority communities to environmental hazards like waste facilities, industrial pollution, and unsafe water, caused by discriminatory land-use and investment patterns. It's listed in EK SPS-6.A.1 as a challenge of urban change in Topic 6.10.
No. Degradation is damage to the environment itself, like a polluted river or eroded soil. Injustice is about distribution, meaning which communities are forced to live closest to that damage. A question asking who bears the burden is asking about injustice.
Discriminatory zoning and investment patterns. Redlining and disinvestment lowered land values in minority neighborhoods, which made them the path of least resistance for siting landfills, highways, and industrial zones, since residents there had the least political power to block them.
Yes. It's named directly in the CED under EK SPS-6.A.1 (Topic 6.10, learning objective 6.10.A), so it can appear in multiple-choice scenarios and support FRQ answers about urban challenges and unequal access to services like safe drinking water.
A city approves a hazardous waste facility in a predominantly low-income minority neighborhood while zoning industry away from wealthy areas. That exact scenario is a common multiple-choice stem, and the correct answer is environmental injustice.
