The history of DDT and pesticides in America is overshadowed by four broad myths. The first myth suggests that DDT was the first insecticide deployed widely by American farmers. The second indicates that DDT was the most toxic pesticide to wildlife and humans alike. The third myth assumes that Rachel Carson’s Silent Spring (1962) was an exposé of the problems of DDT rather than a broad indictment of American dependency on chemical insecticides. The fourth and final myth reassures Americans that the ban on DDT late in 1972 resolved the pesticide paradox in America. Over the course of the 20th century, agricultural chemists have developed insecticides from plants with phytotoxic properties (“botanical” insecticides) and a range of chemicals including heavy metals such as lead and arsenic, chlorinated hydrocarbons like DDT, and organophosphates like parathion. All of the synthetic insecticides carried profound unintended consequences for landscapes and wildlife alike. More recently, chemists have returned to nature and developed chemical analogs of the botanical insecticides, first with the synthetic pyrethroids and now with the neonicotinoids. Despite recent introduction, neonics have become widely used in agriculture and there are suspicions that these chemicals contribute to declines in bees and grassland birds.

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.
