Why the need for a new animal-liberation philosophy? We are owning up to our role in the disruption of our climate. Now, we need to do better than react to serial emergencies. It's time to redefine our role within Earth's great biological community. On Their Own Terms: Animal Liberation for the 21st Century uncovers our personal connections with the current emissions and extinction crises. It explores the human potential to fit our own habitat, while allowing nonhuman communities to thrive in theirs. Explore the hits and misses of animal and environmental advocacy. Learn the ethic underlying the burgeoning vegan movement. And consider some personal goal-setting exercises. This book is a call to community action, and your workshop for social change.
