Which event in the 1970s influenced the rise of environmentalism in the United States?

The publication of "Silent Spring" by Rachel Carson in 1962 is often credited with inspiring the modern environmental movement and raising public awareness about environmental issues, particularly the dangers of pesticides. While the book is actually from the early 1960s and set the stage for environmentalism, its influence continued to resonate strongly into the 1970s. By addressing the harmful impact of chemicals on the environment and human health, Carson's work prompted a shift in public consciousness and contributed to the growing environmental awareness that defined the 1970s. This heightened awareness ultimately led to significant events and legislative actions during that decade, including the establishment of Earth Day and the creation of the EPA.

While the establishment of Earth Day and the creation of the EPA were crucial milestones that helped institutionalize the movement, they largely stemmed from the groundwork laid by Carson's work and public response to environmental degradation. The first Earth Summit in Rio occurred later, in 1992, and while it was significant for global environmental policy, it is not directly tied to the events of the 1970s. Therefore, Carson's "Silent Spring" serves as a foundational text that influenced the rise of environmentalism in that decade.
