Environmental justice refers to equitable distribution of environmental benefits and burdens, ensuring environmentally safe and healthy communities. The environmental justice movement works to protect neighborhoods and other human-populated environments that have been polluted or are at risk of pollution by both public and private industrial policies and practices. Goals of activists in this area are the enactment and enforcement of laws and regulations that prevent pollution, promote cleanup, and protect resources. Environmental justice has become an international cause that includes working to counter threats to remaining biodiverse and resource-rich environments and the Indigenous cultures that live there.
