One of the most important elements of the hippie movement, as proven in the last post, was the ability to envision a world of what can be, as opposed to what is. Part of what made the 1960s so powerful a decade is that it envisioned this notion of change on multiple levels, of which the environment was one such level. "Silent Spring" by Rachel Carson was a work that really galvanized the belief that things need to be done differently and better in terms of the environment. A reexamination of this theme in American thought was also evident. Thoreau's writings on nature and understanding of the natural world was also embraced. As American Culture expanded its own sense of self by looking to other cultures for methods on living, discovery of Native American, Indian, and Eastern cultures, in general, helped to develop an environmental ethos or awareness about how our practices need to be reflective of what can be and away from what is. The previous posts reference to capitalism and its impacts on the environment were also brought out in the time period, suggesting that in moving to a new social order, environmental understanding will be a critical component of this new vision for it was not deemed as important under the capitalist status quo.
