What happened in environmental science in the 1900?

In the 1900s, environmental science began to emerge as a distinct field, influenced by growing awareness of environmental issues. Key events included the establishment of the first national parks, like Yellowstone in the U.S. in 1872, which set a precedent for conservation efforts. The publication of significant works such as Rachel Carson's "Silent Spring" in the early 1960s later highlighted the dangers of pesticides and spurred the modern environmental movement. Overall, this period laid the groundwork for contemporary environmental awareness and policy development.
