An environmental worldview is an individual's beliefs about their role in the world, what constitutes right and wrong environmental behavior, and how the world works. These worldviews can differ between individuals based on their assumptions and values. There are several types of environmental worldviews including egocentric, anthropocentric, and life-centered/earth-centered views. Life-centered and earth-centered views see intrinsic value in all life forms and nature, not just their usefulness to humans. These viewpoints believe humans have a responsibility not to cause species extinction and that we are part of the larger Earth community.
