D. Respect and protect the environment.
The transcendentalist movement was a philosophical and literary movement in the United States in the mid-19th century. It emphasized individualism, intuition, and a connection with nature. Transcendentalists believed that the natural world was a source of spiritual truth and that people should strive to live in harmony with nature. They also believed in the importance of self-reliance and personal growth, rejecting the idea that people should conform to social norms and expectations. The movement was closely associated with writers such as Ralph Waldo Emerson and Henry David Thoreau, who wrote extensively on these themes. Overall, the transcendentalist movement argued that people should live in a way that was respectful and protective of the natural world.
