Question

When talking about enviormental science what is the concept of Ethics by Extension?

Answer 1

Ecologic extension

Marshall's ecologic extension places emphasis not on human rights but on the recognition of the fundamental interdependence of all biological and abiological entities and their essential diversity. Where as Libertarian Extension can be thought of as flowing from a political reflection of the natural world, Ecologic Extension is best thought of as a scientific reflection of the natural world. Ecological Extension is roughly the same classification of Smith’s eco-holism, and it argues for the intrinsic value inherent in collective ecological entities like ecosystems or the global environment as a whole entity.

This category includes James Lovelock's Gaia hypothesis; the theory that the planet earth alters its geo-physiological structure over time in order to ensure the continuation of an equilibrium of evolving organic and inorganic matter. The planet is characterized as a unified, holistic entity with ethical worth of which the human race is of no particular significance in the long run.
