The pattern of disproportionate dumping of toxic waste and other forms of pollution in neighborhoods where the poor and people of color live is called Environmental Racism.
This involves the placement of low-income or minority communities in the proximity of environmentally hazardous or degraded environments, such as toxic waste, pollution and urban decay. The socially marginalized racial minority communities are subjected to disproportionate exposure of pollutants and/or the denial of access to sources of ecological benefits such as clean water, air, and natural resources.
