Casting a curious gaze down on planet Earth, extra-terrestrial beings could well be forgiven for assuming that we humans are programmed in every move we make, by a palm-sized, oblong, slab of glass. More perplexing than that, who on earth could convince them otherwise ?

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.
