Since the 1960s, Latinxs have played prominent roles in the environmental justice movement and in organizations that have defined their members as Hispanic or Latinx environmentalists. Organizers created their own groups in response to their alienation from predominantly white mainstream environmental movements that focused on wilderness preservation and government conservation policies. Latinx community activists, on the other hand, related social justice and grassroots democracy to struggles over public parks and beaches, clean air, clean water, pesticide exposure, and high environmental risks. In the late 1960s and 1970s, organizations like the United Farm Workers (UFW) consciously connected worker safety to environmentalist and consumer concerns about unregulated pesticides, but the majority of environmental groups ignored issues that affected Latinx communities. Eventually, mainstream environmentalists and federal government agencies responded to calls for diversity with increased attention to environmental justice for communities of color in the late 20th century. In recent years, the National Park Service and the US Forest Service have attempted to engage Latinxs through American Hispanic heritage projects and Spanish-language advertising. Previous calls for environmental justice and the youth of the US Latinx population have made many mainstream environmental organizations aware of the need to engage with people of color, although persistent stereotypes about Latinx disinterest in access to public lands and conservation still linger. Newer organizations have worked to engage community members, young people, and departments in the federal government. Latinxs have been and will continue to be critical actors in conversations about local and global environmental issues. Recognition of an existing environmental ethic among Latinx and Spanish-speaking people in the United States would expand the understanding of conservation and environmentalism in American history.
