What really caused the sudden upsurge in concern for preserving Americas environment at the beginiing of the 20th century?

The sudden upsurge in concern for preserving America's environment at the beginning of the 20th century was largely driven by rapid industrialization and urbanization, which led to significant environmental degradation and depletion of Natural Resources. The publication of influential works, such as John Muir's writings and the establishment of the Sierra Club in 1892, raised public awareness about the need for conservation. Additionally, the devastating effects of deforestation, pollution, and the loss of wildlife prompted a growing movement for environmental protection, culminating in the establishment of national parks and the formation of conservation policies. This period marked a shift in public perception, recognizing the intrinsic value of nature and the necessity for sustainable management of natural resources.
