Activity 4.1 - U.S. Environmental History and Major Regulations
During the twentieth century, there was a significant shift in recognizing the complexity and global nature of environmental issues. The Brundtland Report underscored the interdependence of human well-being, ecological systems, social structures, and economic sustainability. This report was pivotal in framing environmental challenges as multidimensional, requiring a holistic approach to understanding and addressing them. U.S. historians studying environmental policies have identified three distinct periods marked by the emergence of new ideas, scientific discoveries, political institutions, and legal frameworks aimed at managing humanity’s impact on the environment.
For early settlers in North America, the concept of “waste” was almost meaningless. Resources seemed inexhaustible, and when one strategy failed, there was always another option available nearby. This mindset of abundance shaped early interactions with the land and continues to influence how some groups perceive humanity’s relationship with natural resources. However, as the population grew and industrialization spread in the mid-19th century, concerns about resource management began to surface. People questioned how the environment could sustain the growing demands for food, raw materials, and living space. Wasteful agricultural practices, soil erosion, and declining crop yields raised alarms, prompting efforts to identify the root causes and implement conservation strategies.
These concerns extended beyond agriculture to deforestation, mining waste, and the exposure of workers to harmful chemicals in industrial settings. Early conservationists, using the scientific method, discovered that many of these issues stemmed from unsustainable behaviors. They demonstrated that such practices not only harmed the environment but also had long-term consequences for human health and societal well-being. These findings laid the foundation for a growing awareness of the need for resource conservation and environmental responsibility.
The transcendentalist movement, led by figures like Ralph Waldo Emerson, added a philosophical dimension to these discussions. Transcendentalism emphasized the importance of personal connections with nature over societal conformity, advocating for a deep, almost spiritual relationship with the natural world. In his essays, Emerson described how humans could connect with the “Universal Being” through their interactions with nature, framing the natural world as essential to human existence. He argued that this connection was not merely poetic but vital for understanding humanity’s place within a larger ecological system.
Although Emerson’s ideas were difficult to express fully through language, they found a visual counterpart in the works of landscape artists, who captured the beauty and majesty of nature in their paintings. These artworks quickly gained popularity, inspiring many to see the environment not just as a resource but as something worthy of admiration and preservation. Beyond environmental concerns, transcendentalism also intersected with broader social issues, including the abolition of slavery, the fight for racial equality, universal suffrage, and gender equity. Although the movement faded in prominence by the late 19th century, its influence profoundly shaped how society viewed humanity’s relationship with nature.
One of the most notable figures inspired by transcendentalism was John Muir. A naturalist, writer, and activist, Muir was instrumental in advocating for the preservation of wilderness areas. His collaboration with President Theodore Roosevelt, often called the “conservation president,” led to the protection of vast tracts of land. Roosevelt’s administration added 225 million acres to the U.S. Forest Service, established wildlife refuges, and created 150 national forests. Muir’s work also inspired the establishment of national parks, a legacy that continues to influence conservation efforts today.
However, despite these early successes, modern attitudes toward the environment often reflect a troubling disconnect. The industrial revolution, fueled by railroads and steamboats, prioritized economic growth over sustainability. Resource exploitation was seen as a necessary cost for creating jobs and advancing society. Waste was normalized, and environmental degradation was often overlooked in the name of progress. Even today, industries remain highly sensitive to economic pressures, frequently prioritizing short-term profits over long-term environmental stewardship.
The challenges we face now are a stark reminder of the lessons from the past. While significant strides have been made in environmental science and policy, many of the same issues persist. Addressing these challenges requires not only technological solutions but also a shift in mindset—one that recognizes the intrinsic value of nature and our collective responsibility to protect it. As Theis and Tomkin (2018) emphasize, the path forward lies in balancing economic growth with ecological sustainability, ensuring that progress does not come at the expense of the planet’s health.
