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.

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.

I'm such an advocate for animal rights and environmental rights.

Know that the same spark of life that is within you, is within all of our animal friends, the desire to live is the same within all of us...

If possessing a higher degree of intelligence does not entitle one human to use another for his or her own ends, how can it entitle humans to exploit non-humans?

The time will come when men such as I will look upon the murder of animals as they now look on the murder of men.
