Narrator
- Narrator: It is the human earthling who tends to dominate the earth, oftentimes treating other fellow earthlings and living beings as mere objects. This is what is meant by 'speciesism'. By analogy with racism and sexism, speciesism is a prejudice or attitude or bias in favor of the interests of the members of one's own species and against those of members of other species.

- Narrator: Since we all inhabit the earth, we are all considered earthlings. There is no sexism, racism, or speciesism in the term 'earthling'. It encompasses each and every one of us: warm- or cold-blooded, mammal, vertebrate or invertebrate, bird, reptile, amphibian, fish and human alike.
