A Marx's Thought - Animal Liberation

i'm going to read a quote here that i like from christian whitkin. He says, since capitalism is the object of our critique, marxu should address all that capital ism destroys. If you do that consistently, you will soon realize that capitalism does not merely exploit and oppress the class of wage laborers. Indeed, you will find references in the works of marx, from his earliest writings through to his late works on economy, to the fact that nature, and therefore, explicitly, animals, are subjugated and exploded by capital.
