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.

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.

For more than a century after the republic’s founding in the 1780s, American law reflected the ideal that the commons—the public domain—should be turned into private property. As Americans became concerned about resource scarcity, waste, and monopolies at the end of the 19th century, reform-minded bureaucrats and scientists convinced Congress to maintain in perpetuity some of the nation’s land as public. This shift offered a measure of protection and an alternative to private property regimes. The federal agencies that primarily manage these lands today—U.S. Forest Service (USFS), National Park Service (NPS), U.S. Fish and Wildlife Service (USFWS), and Bureau of Land Management (BLM)—have worked since their origins in the early decades of the 20th century to fulfill their diverse, competing, evolving missions. Meanwhile, the public and Congress have continually demanded new and different goals as the land itself has functioned and responded in interdependent ways. In the mid-20th century, the agencies intensified their management, hoping they could satisfy the rising—and often conflicting—demands American citizens placed on the public lands. This intensification often worsened public lands’ ecology and increased political conflict, resulting in a series of new laws in the 1960s and 1970s. Those laws strengthened the role of science and the public in influencing agency practices while providing more opportunities for litigation. Predictably, since the late 1970s, these developments have polarized public lands’ politics. The economies, but also the identities, of many Americans remain entwined with the public lands, making political standoffs—over endangered species, oil production, privatizing land, and more—common and increasingly intractable. Because the public lands are national in scope but used by local people for all manner of economic and recreational activities, they have been and remain microcosms of the federal democratic system and all its conflicted nature.
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.

During the American Civil War, Union and Confederate commanders made the capture and destruction of enemy cities a central feature of their military campaigns. They did so for two reasons. First, most mid-19th-century cities had factories, foundries, and warehouses within their borders, churning out and storing war materiel; military officials believed that if they interrupted or incapacitated the enemy’s ability to arm or clothe themselves, the war would end. Second, it was believed that the widespread destruction of property—especially in major or capital cities—would also damage civilians’ morale, undermining their political convictions and decreasing their support for the war effort.
Both Union and Confederate armies bombarded and burned cities with these goals in mind. Sometimes they fought battles on city streets but more often, Union troops initiated long-term sieges in order to capture Confederate cities and demoralize their inhabitants. Soldiers on both sides were motivated by vengeance when they set fire to city businesses and homes; these acts were controversial, as was defensive burning—the deliberate destruction of one’s own urban center in order to keep its war materiel out of the hands of the enemy.
Urban destruction, particularly long-term sieges, took a psychological toll on (mostly southern) city residents. Many were wounded, lost property, or were forced to become refugees. Because of this, the destruction of cities during the American Civil War provoked widespread discussions about the nature of “civilized warfare” and the role that civilians played in military strategy. Both soldiers and civilians tried to make sense of the destruction of cities in writing, and also in illustrations and photographs; images in particular shaped both northern and southern memories of the war and its costs.
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.
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.

Urban water supply and sewage disposal facilities are critical parts of the urban infrastructure. They have enabled cities and their metropolitan areas to function as centers of commerce, industry, entertainment, and human habitation. The evolution of water supply and sewage disposal systems in American cities from 1800 to 2015 is examined, with a focus on major turning points especially in regard to technological decisions, public policy, and environmental and public health issues.
From its inception as a nation in 1789, the United States has engaged in an environmental diplomacy that has included attempts to gain control of resources, as well as formal diplomatic efforts to regulate the use of resources shared with other nations and peoples. American environmental diplomacy has sought to gain control of natural resources, to conserve those resources for the future, and to protect environmental amenities from destruction. As an acquirer of natural resources, the United States has focused on arable land as well as on ocean fisheries, although around 1900, the focus on ocean fisheries turned into a desire to conserve marine resources from unregulated harvesting.
The main 20th-century U.S. goal was to extend beyond its borders its Progressive-era desire to utilize resources efficiently, meaning the greatest good for the greatest number for the longest time. For most of the 20th century, the United States was the leader in promoting global environmental protection through the best science, especially emphasizing wildlife. Near the end of the century, U.S. government science policy was increasingly out of step with global environmental thinking, and the United States often found itself on the outside. Most notably, the attempts to address climate change moved ahead with almost every country in the world except the United States.
While a few monographs focus squarely on environmental diplomacy, it is safe to say that historians have not come close to tapping the potential of the intersection of the environmental and diplomatic history of the United States.
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.
