By the late twentieth century, some decisions about development and environmental protection became embedded in government bodies, but not all Bay Area communities experienced equal protection. Across the nation, communities of color had long confronted environmental racism—the disproportionate burden of environmental hazard and harm placed on underrepresented communities from toxic waste and industrial pollution in their neighborhoods. In the Bay Area, the city of Richmond proved a case in point. Home to the Chevron oil refinery and a host of other industries, neighborhoods in Richmond experienced higher levels of pollution and toxins, habitat destruction, lower qualities of natural resources and environmental amenities, and exploitative dumping. Yet again, residents organized to demand change for their communities, this time for environmental justice—the equal treatment and meaningful involvement of all people in environmental decision-making. By the close of the twentieth century, citizen activists from Richmond and other Bay Area communities played an important role in placing people—not just landscapes—within the environmental agenda. Their ongoing efforts, from shutting down toxic incinerators to ensuring a community voice in decision-making, have reshaped public policies to include the principles of environmental justice at all levels of government.
Environmental Justice arose in the late-1900s and represented an important evolution of environmentalism in California and the United States. In many respects, environmental justice infused the long struggle for Civil Rights into the Environmental Movement. While preservation protected rare landscapes from human development, and conservation balanced that development with environmental protection through regulation, environmental justice placed people and public health at the center of those discussions. In earlier decades, the environmental impact of industrial pollution was measured in habitat destruction and water quality. Environmental justice advocates emphasized how pollution created higher rates of cancer and asthma for residents in the low-income communities–often communities of color–who lived adjacent to those factories. For these marginalized residents, the solution was not just more government regulation, but a greater voice and equal participation in the development and implementation of economic and environmental policy. That process embodied the principles of environmental justice.
