This essay situates animal advocacy as the vital bridge connecting the struggle to protect the rights of human beings with the struggle to protect all living beings. Freeman theorizes why animal advocacy is marginalized among social movements, and explains why the movement should be considered central to a sustainable society that maintains justice for all sentient beings. Focusing on common ground between animal advocacy, human rights, and environmental advocacy an ideological basis is proposed on which these movements can coalesce to resist the ever-increasing corporate exploitation of life. The essay ends by utilizing exploitation of farmed animals as an example of how a justice ethic—a shift away from raising and eating animals—would support the work of environmentalists, animal advocates, and other social justice advocates.
