The omnicidal regimes of 'civilization' and global capitalism have reached their zenith and will end - whether through an ascendent global resistance stronger than this dying world system, or through the cataclysmic adjustments the planet already has initiated, such as those that will ensure its evolution for billions of years to come.
A politics of total liberation could forge alliances more positive and powerful than anything yet created. It could emancipate not just one class, interest group, or even the entire human species from the grip of a nihilistic power elite (that value nothing but power and profit), but also animal communities everywhere, ecosystems worldwide, and the dynamic energies of evolution and speciation currently blocked by human "progress."
If physical force is needed to save an animal from attack, then that force is a legitimate form of what I call "extensional self defense." This principle mirrors US penal code statutes known as the "necessity defense," which can be invoked when a defendant believed that an illegal act was necessary to avoid great and imminent harm. One only needs to expand this concept slightly to cover actions that are increasingly desperate and necessary to protect animals from the total war against them.
There can be no full or even adequate understanding of the systemic problems of capitalist society, of the origins and dynamics of hierarchy, and of a future rational, autonomous, ethical, and ecological society until we address the 10,000-year legacy of speciesism and the barbaric exploitation of other animals.
We now face the grim choice posed by revolutionaries over the last two centuries, which involved "revolution or barbarism." Our situation has deteriorated so dramatically that we must choose between revolution or ecological collapse, mass extinction, and possibly our own demise. The twenty-first century is a time of reckoning.
