Environmental ethics examines the moral relationship between humans and the environment. It believes humans are part of both society and the natural world of plants, animals, and ecosystems. There are three main branches: anthropocentrism views humans as having authority over nature, biocentrism grants moral status to all life, and ecocentrism values nature itself. Environmental ethics helps make people aware of destructive human impacts and teaches respect for diverse life forms. It is concerned with responsible conduct regarding nature and natural resources.
