"Earthlings" chronicles the day-to-day practices of industries that rely on animals for profit, using hidden cameras and never-before-seen footage. Narrated by Joaquin Phoenix, the film exposes animal abuse in factory farms, pet stores, puppy mills, and animal experimentation. Drawing parallels between speciesism and racism, sexism, and other forms of oppression, Earthlings aims to raise awareness about the treatment of non-human animals and promote compassion for all beings.
