A watershed, or turning point, refers to a critical moment in a process or situation that leads to significant change. It often marks a decisive shift in direction, influencing future events or outcomes. In various contexts, such as history, personal development, or environmental science, a watershed can signify a moment when things can no longer return to the way they were. In environmental terms, a watershed is also a land area that channels rainfall and snowmelt to creeks, streams, and rivers. This geographical feature plays a crucial role in managing water resources and ecosystems. Understanding both meanings of "watershed" helps clarify its importance in different fields, from climate change to personal growth.
