Biotic ethics (also called life-centered ethics) is a branch of ethics that values not only species and biospheres, but life itself. On this basis, biotic ethics defines a human purpose to secure and propagate life. These principles are related to bioethics, and to environmental ethics that seek to conserve existing species. However, biotic ethics value more generally organic gene/protein life itself, the structures and processes shared by all the biota. These processes result in self-propagation, an effective purpose that humans share with all life. Belonging to life then implies a human purpose to safeguard and propagate life. This purpose defines basic moral values: Acts that sustain life are good, and acts that destroy life are evil. Panbiotic ethics extends these principles to space,
