Spanning countries across the globe, the antinuclear movement was the combined effort of millions of people to challenge the superpowers’ reliance on nuclear weapons during the Cold War. Encompassing an array of tactics, from radical dissent to public protest to opposition within the government, this movement succeeded in constraining the arms race and helping to make the use of nuclear weapons politically unacceptable. Antinuclear activists were critical to the establishment of arms control treaties, although they failed to achieve the abolition of nuclear weapons, as anticommunists, national security officials, and proponents of nuclear deterrence within the United States and Soviet Union actively opposed the movement. Opposition to nuclear weapons evolved in tandem with the Cold War and the arms race, leading to a rapid decline in antinuclear activism after the Cold War ended.

Between 1964 and 2017, the United States adopted the concept of environmental policy as a new focus for a broad range of previously disparate policy issues affecting human interactions with the natural environment. These policies ranged from environmental health, pollution, and toxic exposure to management of ecosystems, resources, and use of the public lands, environmental aspects of urbanization, agricultural practices, and energy use, and negotiation of international agreements to address global environmental problems. In doing so, it nationalized many responsibilities that had previously been considered primarily state or local matters. It changed the United States’ approach to federalism by authorizing new powers for the federal government to set national minimum environmental standards and regulatory frameworks with the states mandated to participate in their implementation and compliance. Finally, it explicitly formalized administrative procedures for federal environmental decision-making with stricter requirements for scientific and economic justification rather than merely administrative discretion. In addition, it greatly increased public access to information and opportunities for input, as well as for judicial review, thus allowing citizen advocates for environmental protection and appreciative uses equal legitimacy with commodity producers to voice their preferences for use of public environmental resources.
These policies initially reflected widespread public demand and broad bipartisan support. Over several decades, however, they became flashpoints, first, between business interests and environmental advocacy groups and, subsequently, between increasingly ideological and partisan agendas concerning the role of the federal government. Beginning in the 1980s, the long-standing Progressive ideal of the “public interest” was increasingly supplanted by a narrative of “government overreach,” and the 1990s witnessed campaigns to delegitimize the underlying evidence justifying environmental policies by labeling it “junk science” or a “hoax.”
From the 1980s forward, the stated priorities of environmental policy vacillated repeatedly between presidential administrations and Congresses supporting continuation and expansion of environmental protection and preservation policies versus those seeking to weaken or even reverse protections in favor of private-property rights and more damaging uses of resources. Yet despite these apparent shifts, the basic environmental laws and policies enacted during the 1970s remained largely in place: political gridlock, in effect, maintained the status quo, with the addition of a very few innovations such as “cap and trade” policies. One reason was that environmental policies retained considerable latent public support: in electoral campaigns, they were often overshadowed by economic and other issues, but they still aroused widespread support in their defense when threatened. Another reason was that decisions by the courts also continued to reaffirm many existing policies and to reject attempts to dismantle them.
With the election of Donald Trump in 2016, along with conservative majorities in both houses of Congress, US environmental policy came under the most hostile and wide-ranging attack since its origins. More than almost any other issue, the incoming president targeted environmental policy for rhetorical attacks and budget cuts, and sought to eradicate the executive policies of his predecessor, weaken or rescind protective regulations, and undermine the regulatory and even the scientific capacity of the federal environmental agencies. In the early 21st century, it is as yet unclear how much of his agenda will actually be accomplished, or whether, as in past attempts, much of it will ultimately be blocked by Congress, the courts, public backlash, and business and state government interests seeking stable policy expectations rather than disruptive deregulation.
In September 1962, the National Farm Workers Association (NFWA) held its first convention in Fresno, California, initiating a multiracial movement that would result in the creation of United Farm Workers (UFW) and the first contracts for farm workers in the state of California. Led by Cesar Chavez, the union contributed a number of innovations to the art of social protest, including the most successful consumer boycott in the history of the United States. Chavez welcomed contributions from numerous ethnic and racial groups, men and women, young and old. For a time, the UFW was the realization of Martin Luther King Jr.’s beloved community—people from different backgrounds coming together to create a socially just world. During the 1970s, Chavez struggled to maintain the momentum created by the boycott as the state of California became more involved in adjudicating labor disputes under the California Agricultural Labor Relations Act (ALRA). Although Chavez and the UFW ultimately failed to establish a permanent, national union, their successes and strategies continue to influence movements for farm worker justice today.

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.
The development of nuclear technology had a profound influence on the global environment following the Second World War, with ramifications for scientific research, the modern environmental movement, and conceptualizations of pollution more broadly. Government sponsorship of studies on nuclear fallout and waste dramatically reconfigured the field of ecology, leading to the widespread adoption of the ecosystem concept and new understandings of food webs as well as biogeochemical cycles. These scientific endeavors of the atomic age came to play a key role in the formation of environmental research to address a variety of pollution problems in industrialized countries. Concern about invisible radiation served as a foundation for new ways of thinking about chemical risks for activists like Rachel Carson and Barry Commoner as well as many scientists, government officials, and the broader public. Their reservations were not unwarranted, as nuclear weapons and waste resulted in radioactive contamination of the environment around nuclear-testing sites and especially fuel-production facilities. Scholars date the start of the “Anthropocene” period, during which human activity began to have substantial effects on the environment, variously from the beginning of human farming roughly 8,000 years ago to the emergence of industrialism in the 19th century. But all agree that the advent of nuclear weapons and power has dramatically changed the potential for environmental alterations. Our ongoing attempts to harness the benefits of the atomic age while lessening its negative impacts will need to confront the substantial environmental and public-health issues that have plagued nuclear technology since its inception.

American food in the twentieth and twenty-first centuries is characterized by abundance. Unlike the hardscrabble existence of many earlier Americans, the “Golden Age of Agriculture” brought the bounty produced in fields across the United States to both consumers and producers. While the “Golden Age” technically ended as World War I began, larger quantities of relatively inexpensive food became the norm for most Americans as more fresh foods, rather than staple crops, made their way to urban centers and rising real wages made it easier to purchase these comestibles.
The application of science and technology to food production from the field to the kitchen cabinet, or even more crucially the refrigerator by the mid-1930s, reflects the changing demographics and affluence of American society as much as it does the inventiveness of scientists and entrepreneurs. Perhaps the single most important symbol of overabundance in the United States is the postwar Green Revolution. The vast increase in agricultural production based on improved agronomics, provoked both praise and criticism as exemplified by Time magazine’s critique of Rachel Carson’s Silent Spring in September 1962 or more recently the politics of genetically modified foods.
Reflecting that which occurred at the turn of the twentieth century, food production, politics, and policy at the turn of the twenty-first century has become a proxy for larger ideological agendas and the fractured nature of class in the United States. Battles over the following issues speak to which Americans have access to affordable, nutritious food: organic versus conventional farming, antibiotic use in meat production, dissemination of food stamps, contraction of farm subsidies, the rapid growth of “dollar stores,” alternative diets (organic, vegetarian, vegan, paleo, etc.), and, perhaps most ubiquitous of all, the “obesity epidemic.” These arguments carry moral and ethical values as each side deems some foods and diets virtuous, and others corrupting. While Americans have long held a variety of food ideologies that meld health, politics, and morality, exemplified by Sylvester Graham and John Harvey Kellogg in the nineteenth and early twentieth centuries, among others, newer constructions of these ideologies reflect concerns over the environment, rural Americans, climate change, self-determination, and the role of government in individual lives. In other words, food can be used as a lens to understand larger issues in American society while at the same time allowing historians to explore the intimate details of everyday life.
Humans have utilized American forests for a wide variety of uses from the pre-Columbian period to the present. Native Americans heavily shaped forests to serve their needs, helping to create fire ecologies in many forests. English settlers harvested these forests for trade, to clear land, and for domestic purposes. The arrival of the Industrial Revolution in the early 19th century rapidly expanded the rate of logging. By the Civil War, many areas of the Northeast were logged out. Post–Civil War forests in the Great Lakes states, the South, and then the Pacific Northwest fell with increasing speed to feed the insatiable demands of the American economy, facilitated by rapid technological innovation that allowed for growing cuts. By the late 19th century, growing concerns about the future of American timber supplies spurred the conservation movement, personified by forester Gifford Pinchot and the creation of the U.S. Forest Service with Pinchot as its head in 1905. After World War II, the Forest Service worked closely with the timber industry to cut wide swaths of the nation’s last virgin forests. These gargantuan harvests led to the growth of the environmental movement. Beginning in the 1970s, environmentalists began to use legal means to halt logging in the ancient forests, and the listing of the northern spotted owl under the Endangered Species Act was the final blow to most logging on Forest Service lands in the Northwest. Yet not only does the timber industry remain a major employer in forested parts of the nation today, but alternative forest economies have also developed around more sustainable industries such as tourism.
The national parks of the United States have been one of the country’s most popular federal initiatives, and popular not only within the nation but across the globe. The first park was Yellowstone, established in 1872, and since then almost sixty national parks have been added, along with hundreds of monuments, protected rivers and seashores, and important historical sites as well as natural preserves. In 1916 the parks were put under the National Park Service, which has managed them primarily as scenic treasures for growing numbers of tourists. Ecologically minded scientists, however, have challenged that stewardship and called for restoration of parks to their natural conditions, defined as their ecological integrity before white Europeans intervened. The most influential voice in the history of park philosophy remains John Muir, the California naturalist and Yosemite enthusiast and himself a proto-ecologist, who saw the parks as sacred places for a modern nation, where reverence for nature and respect for science might coexist and where tourists could be educated in environmental values. As other nations have created their own park systems, similar debates have occurred. While parks may seem like a great modern idea, this idea has always been embedded in cultural and social change—and subject to struggles over what that “idea” should be.

Technology and environmental history are both relatively young disciplines among Americanists, and during their early years they developed as distinctly different and even antithetical fields, at least in topical terms. Historians of technology initially focused on human-made and presumably “unnatural” technologies, whereas environmental historians focused on nonhuman and presumably “natural” environments. However, in more recent decades, both disciplines have moved beyond this oppositional framing. Historians of technology increasingly came to view anthropogenic artifacts such as cities, domesticated animals, and machines as extensions of the natural world rather than its antithesis. Even the British and American Industrial Revolutions constituted not a distancing of humans from nature, as some scholars have suggested, but rather a deepening entanglement with the material environment. At the same time, many environmental historians were moving beyond the field’s initial emphasis on the ideal of an American and often Western “wilderness” to embrace a concept of the environment as including humans and productive work. Nonetheless, many environmental historians continued to emphasize the independent agency of the nonhuman environment of organisms and things. This insistence that not everything could be reduced to human culture remained the field’s most distinctive feature.
Since the turn of millennium, the two fields have increasingly come together in a variety of synthetic approaches, including Actor Network Theory, envirotechnical analysis, and neomaterialist theory. As the influence of the cultural turn has waned, the environmental historians’ emphasis on the independent agency of the nonhuman has come to the fore, gaining wider influence as it is applied to the dynamic “nature” or “wildness” that some scholars argue exists within both the technological and natural environment. The foundational distinctions between the history of technology and environmental history may now be giving way to more materially rooted attempts to understand how a dynamic hybrid environment helps to create human history in all of its dimensions—cultural, social, and biological.
