Animal liberation activists may not be experts in agriculture, restoration ecology, paleo anthropology, etc.; but animal liberation activists tend to have a special compassion for and connection with nonhumanimals from which future Earth could benefit. This in itself qualifies them to assess notions on a post-civ future. Liberation theories have roles in defining culture, challenging authority and taking action liberating oppressed life. Animal liberation and anarcho-primitivism are closely connected ideas, change agents with overlapping activism of and for humans, nonhuman animals and Earth. Even if human nature to avoid conflict is strong and no end to the conflict seems in sight, continuing the process of critique and experimentation between the two camps may some day bring shared understandings helping both actualize a freer thriving world.
