Human societies impose a state of being “as if” parasitical onto nonhuman animals, simply by claiming nature to be a resource “exclusively usable” by humans. Nature is seen as a resource existent to serve human needs and desires, to be exploited. Nature is not regarded as an animal habitat with its animal inhabitants, etc.
By living out this attitude and worldview of: “subject the earth to your will and exploit it to your needs”, nonhuman animals are automatically put either into the position of being degradable and exploitable, subjectable, or they are seen as parasitical, just barely allowed to enter the human garden eden, so one could say.
This is a long subject and it came to my mind quite clearly today … ,so, well I wanted to quickly note it down. I am gonna write more about this angle of homocentrism later, of course.
Homocentrism makes blind to perspectives that don’t serve the “human interest”.
