Environmental History

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.

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.

Energy systems have played a significant role in U.S. history; some scholars claim that they have determined a number of other developments. From the colonial period to the present, Americans have shifted from depending largely on wood and their own bodies, as well as the labor of draft animals; to harnessing water power; to building steam engines; to extracting fossil fuels—first coal and then oil; to distributing electrical power through a grid. Each shift has been accompanied by a number of other striking changes, especially in the modern period associated with fossil fuels. By the late 19th century, in part thanks to new energy systems, Americans were embracing industrialization, urbanization, consumerism, and, in a common contemporary phrase, “the annihilation of space and time.” Today, in the era of climate change, the focus tends to be on the production or supply side of energy systems, but a historical perspective reminds us to consider the consumption or demand side as well. Just as important as the striking of oil in Beaumont, Texas, in 1901, was the development of new assumptions about how much energy people needed to sustain their lives and how much work they could be expected to do. Clearly, Americans are still grappling with the question of whether their society’s heavy investment in coal- and petroleum-based energy systems has been worthwhile.

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.

Few developments in human history match the demographic consequences of the arrival of Europeans in the Americas. Between 1500 and 1900 the human populations of the Americas were traBnsformed. Countless American Indians died as Europeans established themselves, and imported Africans as slaves, in the Americas. Much of the mortality came from epidemics that swept through Indian country. The historical record is full of dramatic stories of smallpox, measles, influenza, and acute contagious diseases striking American Indian communities, causing untold suffering and facilitating European conquest. Some scholars have gone so far as to invoke the irresistible power of natural selection to explain what happened. They argue that the long isolation of Native Americans from other human populations left them uniquely susceptible to the Eurasian pathogens that accompanied European explorers and settlers; nothing could have been done to prevent the inevitable decimation of American Indians. The reality, however, is more complex. Scientists have not found convincing evidence that American Indians had a genetic susceptibility to infectious diseases. Meanwhile, it is clear that the conditions of life before and after colonization could have left Indians vulnerable to a host of diseases. Many American populations had been struggling to subsist, with declining populations, before Europeans arrived; the chaos, warfare, and demoralization that accompanied colonization made things worse. Seen from this perspective, the devastating mortality was not the result of the forces of evolution and natural selection but rather stemmed from social, economic, and political forces at work during encounter and colonization. Getting the story correct is essential. American Indians in the United States, and indigenous populations worldwide, still suffer dire health inequalities. Although smallpox is gone and many of the old infections are well controlled, new diseases have risen to prominence, especially heart disease, diabetes, cancer, substance abuse, and mental illness. The stories we tell about the history of epidemics in Indian country influence the policies we pursue to alleviate them today.
