In the 1985 CBC series "A Planet For the Taking", Dr. David Suzuki explored the Old Testament roots of anthropocentrism and how it shaped our view of non-human animals.
Christianity has a strong tendency toward anthropocentrism, as emphasized in the early environmentalist critique of Lynn Townsend White, Jr..
Martyn J. Fogg rebutted these ideas by delineating four potential rationales on which to evaluate the ethics of terraforming—anthropocentrism, zoocentrism, ecocentrism, and preservationism—roughly forming a spectrum from placing the most value on human utility to placing the most value on preserving nature.
