How did environmental revolution start?

The environmental revolution began in the mid-20th century as awareness grew about the detrimental effects of industrialization and human activity on the planet. Key events, such as the publication of Rachel Carson's "Silent Spring" in 1962, highlighted issues like pesticide use and pollution. This period saw the rise of environmental movements, the establishment of Earth Day in 1970, and the formation of various environmental organizations, all advocating for sustainable practices and greater ecological awareness. These efforts laid the groundwork for modern environmental policy and activism.
