From the founding of the American republic through the 19th century, the nation’s environmental policy mostly centered on promoting American settlers’ conquest of the frontier. Early federal interventions, whether railroad and canal subsidies or land grant acts, led to rapid transformations of the natural environment that inspired a conservation movement by the end of the 19th century. Led by activists and policymakers, this movement sought to protect America’s resources now jeopardized by expansive industrial infrastructure. During the Gilded Age, the federal government established the world’s first national parks, and in the Progressive Era, politicians such as President Theodore Roosevelt called for the federal government to play a central role in ensuring the efficient utilization of the nation’s ecological bounty. By the early 1900s, conservationists established new government agencies, such as the U.S. Forest Service and the Bureau of Reclamation, to regulate the consumption of trees, water, and other valuable natural assets. Wise-use was the watchword of the day, with environmental managers in DC’s bureaucracy focused mainly on protecting the economic value latent in America’s ecosystems. However, other groups, such as the Wilderness Society, proved successful at redirecting policy prescriptions toward preserving beautiful and wild spaces, not just conserving resources central to capitalist enterprise. In the 1960s and 1970s, suburban and urban environmental activists attracted federal regulators’ attention to contaminated soil and water under their feet. The era of ecology had arrived, and the federal government now had broad powers through the Environmental Protection Agency (EPA) to manage ecosystems that stretched across the continent. But from the 1980s to the 2010s, the federal government’s authority to regulate the environment waxed and waned as economic crises, often exacerbated by oil shortages, brought environmental agencies under fire. The Rooseveltian logic of the Progressive Era, which said that America’s economic growth depended on federal oversight of the environment, came under assault from neoliberal disciples of Ronald Reagan, who argued that environmental regulations were in fact the root cause of economic stagnation in America, not a powerful prescription against it. What the country needed, according to the reformers of the New Right, was unregulated expansion into new frontiers. By the 2010s, the contours of these new frontiers were clear: deep-water oil drilling, Bakken shale exploration, and tar-sand excavation in Alberta, Canada. In many ways, the frontier conquest doctrine of colonial Americans found new life in deregulatory U.S. environmental policy pitched by conservatives in the wake of the Reagan Revolution. Never wholly dominant, this ethos carried on into the era of Donald Trump’s presidency.
President Abraham Lincoln signed the law that established the Department of Agriculture in 1862 and in 1889, President Grover Cleveland signed the law that raised the Department to Cabinet status. Thus, by 1900 the US Department of Agriculture had been established for nearly four decades, had been a Cabinet-level department for one, and was recognized as a rising star among agricultural science institutions. Over the first half of the next century, the USDA would grow beyond its scientific research roots to assume a role in supporting rural and farm life more broadly, with a presence that reached across the nation. The Department acquired regulatory responsibilities in plant and animal health and food safety and quality, added research in farm management and agricultural economics, provided extension services to reach farms and rural communities in all regions, and created conservation and forestry programs to protect natural resources and prevent soil erosion and flooding across the geographical diversity of rural America. The Department gained additional responsibility for delivering credit, price supports, supply management, and rural rehabilitation programs during the severe economic depression that disrupted the agricultural economy and rural life from 1920 to 1940, while building efficient systems for encouraging production and facilitating distribution of food during the crises of World War I and World War II that bounded those decades. In the process, the Department became a pioneer in developing the regulatory state as well as in piloting programs and bureaucratic systems that empowered cooperative leadership at the federal, state, and local levels and democratic participation in implementing programs in local communities.
